Answer:
1) x = 2
2) x = 7
3) x = 12
4) x = 4
5) x = 8
6) x = 3
Step-by-step explanation:
1) 7x + 9 = 23
(7x + 9) + (-9) = 23 + (-9)
7x + 9 - 9 = 23 - 9
7x = 14
7x/7 = 14/7
x = 2
2) 5x + 7 = 42
(5x + 7) + (-7) = 42 + (-7)
x = 7
3) 4x+3=51
(4x + 3) + (-3) = 51 + (-3)
4x + 3 - 3 = 51 - 3
x = 12
4) 9x+5=41
(9x + 5) + (-5) = 41 + (-5)
x = 4
5) 4x+2=34
(4x + 2) + (-2) = 34 + (-2)
x = 8
6) 11x+3=36
(11x + 3) + (-3) = 36 + (-3)
11x + 3 - 3 = 36 - 3
x = 3

Bob's car can go
111 miles on tank
of gas. How far can it
go on a full tank?
PLEASE HURRY
Answer:
296 miles
Step-by-step explanation:
Use a proportion:
111/( 3/8) = x/ 1
Cross Multiply
(3/8)x = 111
Multiply both sides by 8/3 ; reciprocal
x = (8/3) (111)
x = 296 miles
One banana contains 1.3 grams of
protein. How much protein is in 0.5
of a banana?
Answer:
0.65 grams
Step-by-step explanation:
0.5 of a banana is 1/2 of a banana. A full banana has 1.3g which means we can divide this by 2 to find the amount of protein in half a banana. 1.3 ÷ 2 = 0.65. There is 0.65g of protein in 0.5 of a banana.
Hope this helps!
Protein is 0.65 gram in 0.5 of a banana.
How much protein is in 0.5 of a banana?
By Unitary method,we can solve this problem.
But now question is what is the use of Unitary method ?
By some examples we can understand this concept.
Let cost of 5 pens is 50 rupees.
By Unitary method, cost of 1 pen is
[tex]\frac{50}{5} \\ = 10 \: rupees[/tex]
Cost of 100 pens is [tex](100 \times 10) = 1000 \: rupees[/tex]
Again length of 1 rope is 5 m
Then by Unitary method length of 5 rope is [tex](5 \times 5) = 25 \: m[/tex]
Here given,One banana contains 1.3 grams of protein.
According to question we can say one banana has 1.3 grams of protein.
We want to find quantity of protein in 0.5 banana.
We know,
[tex]0.5 \: of \: banana = \frac{1}{2} \: of \: banana[/tex]
Here quantity of protein in 1 banana is 1.3 grams
So,by Unitary method quantity of protein in [tex] \frac{1}{2} [/tex] banana is
[tex](1.3 \times \frac{1}{2} ) \: grams \\ = \frac{13}{10} \times \frac{1}{2} \\ = 0.65 \: grams[/tex]
Therefore 0.5 banana contain 0.65 grams protein.

Answer:
B) <
Step-by-step explanation:
Since both numbers are being multiplied by 10^-5, we can completely cut that part out of the inequality and instead just compare the values 3.2 and 4.6. It is obvious when looking at the problem that 3.2 is smaller than 4.6, so we will use the less than symbol <.

How do you find the percentage off of a price
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Step-by-step explanation:
Example:
Find the original price (for example $90)Get the the discount percentage (for example 20%)Calculate the savings: 20% of $90 = $18Subtract the savings from the original price to get the sale price: $90 - $18 = $72You're all set!Discount formula:
(original_price * discount / 100)
_____________________________________________________
Percentage discount is a discount that is given to a product or service that is given as an amount per hundred. For example, a percentage discount of 20% would mean that an item that originally cost $100 would now cost $80. This is common with promotional and seasonal sales, as a way of encouraging consumers to buy an item at a reduced cost.
___________________________________________________
$279 - $55.80 = $223.20
You would therefore be saving $55.80 on the purchase for a final price of $223.20.
For this calculator, a "stackable additional discount" means getting a further percent off of a product after a discount is applied. Using the same example, assume that the 20% discount is a discount applied by the store to the product. If you have a coupon for another 15% off, the 15% off would then be applied to the discounted price of $223.20. It is not a total of 35% off of the original price. It is less:
15% of $223.20 = $33.48
$223.20 - $33.48 = $189.72
Thus, with a 20% discount off of $279, and an additional 15% off of that discounted price, you would end up saving a total of:
$55.80 + $33.48 = $89.28
This equates to a 32% discount, rather than a 35% discount, and this calculation is how the calculator is intended to be used. As an example, to more efficiently compute the discount described above:
Final price = (0.80 × 279) × 0.85 = $189.72
This is because 80% of the original price is the same as subtracting 20% of the original price from the original price. The same is true for 85% and 15% case applied to the discounted price.

Answer:
We’re are the choices
Step-by-step explanation:
Selina had been renting for 18 months when there was a flood. The total cost to replace her damaged belongings was $2,160. 0. Then 20.833 percent would Selina have saved if she had a renters' insurance policy at a monthly cost of $25. 00
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that
Selina had been renting for 18 months when there was a flood.

$450
Now let us remove the amount which got in insurance from total rent.
$2,160. 0-$450
=1710
Now we have to find 450 is what percentage of 2160.
450/2160×100

{4z=8}
{3x-2z=11}
{x-4y+z=11}
Step-by-step explanation:
4z = 8
z = 8/4

F(n)=4n
g(n)=n2+2n
find f(g(-6))
Answer:
When f(n) = 4n and g(n) = n² + 2n, f(g(-6)) = 96.
Step-by-step explanation:
To evaluate f(g(-6)), first find g(-6).
g(n) = n² + 2n
Substitute value.
g(-6) = (-6)² + 2(-6)
Square -6. Remember that (-x)² = x²
g(-6) = 36 + 2(-6)
Multiply 2 and -6.
g(-6) = 36 - 12
Subtract 12 from 36.
g(-6) = 24.
Now knowing this, substitute that value into f(n).
f(g(-6)) = f(24)
f(n) = 4n
Substitute value.
f(24) = 4(24)
Multiply 4 and 24.
f(24) = 96.
This is a graphing problem and I am trying to find the x-intercepts and the y-intercepts. Please show me the full steps. I really appreciate it thank you.
Answer:
Step-by-step explanation:
the x intercept occurs when y=0
[tex]0=\frac{2x+6}{x-1}\\0=2x+6\\x=-3\\(-3,0)[/tex]
The y intercept occurs when x=0
[tex]y=\frac{2(0)+6}{0-1}=-6\\(0,-6)[/tex]
Answer:
Below in bold.
Step-by-step explanation:
To find the x -intercept put f(x) = 0:
(2x - 6)/(x - 1) = 0
2x - 6 = 0
2x = 6
x = 3
So the x-intercept is at the point(3, 0).
To find the y-intercept put x = 0:
y = (2(0) - 6)/(0 - 1)
= -6/-1
= 6
So the x-intercept is at the point(0, 6).

Each minute, a faucet allows 4/9 gallons of water to enter a large tub, and the drain allows 8/9 gallons to leave the tub.
What is the change in the amount of liquid in the tub after 1/3 minute?
Enter your answer as a fraction in lowest terms in the box
Answer:
Step-by-step explanation:
The amount of water in the bathtub per minute:4/9-8/9=-4/9;
liquid after:1/3* (-4/9)=-4/27
If the change in the amount of liquid in the tub for 1 minute is 4/9, The change in the amount of liquid in the tub after 1/3 minute will be 4/27.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that, Each minute, a faucet allows 4/9 gallons of water to enter a large tub, and the drain allows 8/9 gallons to leave the tub.
The rate of net flow of the water = Water outgoing - Water ingoing
The rate of net flow of the water = 8/9 - 4/9
The rate of net flow of the water =4/9
The change in the amount of liquid in the tub after 1/3 minute is,
=4/9 × 1/3
=4/27
Thus, if the change in the amount of liquid in the tub for 1 minute is 4/9, The change in the amount of liquid in the tub after 1/3 minute will be 4/27.

Answer:
20 out of 120 times
Step-by-step explanation:
As others have said, the general formula is:
expected successes = probability*number of trials
Perhaps an easier question: If you roll a die 6 times, how many 4s would you expect to get?
1, right? 1 out of every 6. That’s what 1/6 means.
If you roll a die 12 times, you expect 2. 2/12 = 1/6
Steps for 4-6h-8h=60
Answer:
To solve for h, isolate the “h” on one side of the equation.
Combine like terms on the left sides (h). When combing like terms add and subtract as normal and attach the variable.
4-14h=60
Subtract 4 from both sides.
-14h=56
Divide both sides by -14.
h=-4
Hope this helps! :)
Answer:
h = -4.
Step-by-step explanation:
4-6h-8h=60
4-4-6h-8h = 60-4
-14h = 56
h = 56/-14

Pete saw that he was 200 yards from shore when he dove out of the boat. It took him 49 seconds to swim the first 50 yards. At that rate, how much longer will it take to reach the shore?
tysm<3
Answer:
147 seconds to get to the shore(after the 49 seconds)
Step-by-step explanation:
If Pete swam at a constant speed of 50 yards/49 seconds, you just have to multiply that by four, to get 200 yards. If you want the total time from his boat to shore, that is 196. If you want how much longer it would be, it would be 147 seconds
