Answer:
12
Step-by-step explanation:
(-15)/(-18) = 10/x cross multiply expressions
-15x = -180 since both sides are negative we can write without the sign
15x = 180 divide both sides by 15
x = 12
Simplify the following expression.
8x+5−11x+ x−3
[tex]8x + 5 - 11x + x - 3 \\ = 8x - 11x + x + 5 - 3 \\ = - 2x + 2[/tex]
Answer:-2x + 2

What is a sales tax decalculator?
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.

x<=119
Step-by-step explanation:
If it's no greater that the mean is 120 seconds, then the sum of the seconds should be 600. 600-118-129-120-114=119
So x should be less or equal to 119.

Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.
Mikey knows that the inequality representing this situation is 112 + x ≤ 260.
Select from the drop-down menu to correctly interpret the solution of this inequality.
Mikey's family can drive_____more miles before they need to refill the gas tank.
A. at most 148
B. at least 148
C. more than 372
D. more than 372
Answer:
A
Step by step:
you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.
Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the given situation, the required inequality would be as
⇒ 112 + x ≤ 260
To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.
⇒ 112 + x - 112 ≤ 260 - 112
⇒ x ≤ 148
This indicates that the maximum distance that may be traveled before filling up is 148 miles.
Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.

While eating lunch, Vivian ate 65% of the carrots she had in her bag. There were 20 carrots in her bag before she ate any. How many carrots did Vivian have left in her bag after she ate?
Answer:
Vivian would have 7 carrots left to spare if she ate 65% of the carrots in the bag.
Step-by-step explanation: Since 65% of 20 carrots equals 13 carrots, we would do 20 - 13. In which equals 7 so she has 7 carrots left in fer bag
Equation: 20-x=?
Solution: 20 - 13=7

Jazmyn uses 2 gallons of paint to paint 5 walls. He uses 4 gallons of paint to paint 10 walls. How many gallons of paint does he use per wall?
Answer:
2/5 gallons
Step-by-step explanation:
If it takes 2 gallons of paint to paint 5 walls, then the amount of gallons used per wall can be calculated by comparison
[tex]5 walls = 2 gallons \\ 1 \: wall = x \: gallons \\ by \: cross \: multiplication \\ 5 \times x = 2 \times 1 \\ 5x = 2 \\ x = \frac{2}{5} [/tex]
Hence, 2/5 gallons of paint is used per wall.
Brandon buys a radio for $48.81 in a state where the sales tax is 7%.
can someone pls help?
Answer:
$48.81 x 0.07 = 3.4167
$48.81 + $3.4167 = $52.2267
$52.23
Step-by-step explanation:
The shirt cost $48.81, and the sales tax is 7%. First convert the 7% into a decimal and you get 0.07, and then multiply that to the $48.81. You get left with $3.4167 and then add that to the $48.81 to get $52.2267. But, you have to shorten the numbers to make it look like money by simplifing. So the total is $52.23.

Answer:
length= 35 feet and width= 10 feet
Step-by-step explanation:
You are given the perimeter of the rectangular deck is
90 feet.
2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5
Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.
2x (4 x width - 5) + 2 x width =90
Distribute the 2 though
8 x width - 10 + 2 x width = 90
Combine like terms with width.
10 x width - 10 = 90
Add 10 to both sides.
10 x width = 100
Divide both sides by 10 width = 100
Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5
Length = 4 x 10 - 5
Length = 40 - 5
Length = 35

How do you write (4)(25)-300 as an addition equation
(4)(25) - 300 can be written as an addition equation: 100 + (-300).
What is an equation?An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.
Given:
An equation is (4)(25)-300.
To write (4)(25)-300 as an addition equation,
we can break it down into two separate addition equations as follows:
(4)(25) - 300 = (4)(25) + (-300)
To solve this further,
substitute the value 25 x 4 = 100 to the above equation, we get,
= 100 + (-300)
Therefore, the equation in the required form is 100 + (-300).

The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?
₋₋₋₋₋₋₋₋ °F per hour
Answer:
-3.5
Step-by-step explanation:
As there was a total change of -21, that would be the first part of your equation:
-21
As 6 hours had passed and you are trying to find the mean, your equation would now be:
-21 ÷ 6 = ?
Now you can solve the equation, and the answer is -3.5°F per hour.
The mean change in temperature per hour is -3.5 °F.
what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total change in the outdoor temperature over 6 hours was -21°F
So, in one hour the mean change in temperature
= -21/6
= -3.5 °F
Hence, the mean change in temperature per hour is -3.5 °F.

An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.
Answer:
The balance in the bank after 5 years of 6.5% interest is $5,300.
Step-by-step explanation:
*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*
So every 5 years the balance earns 0.065 of 4,000 dollars.
This would make our equation:
4000 + (4000 x .065 x 5 )
= 4000 + (1300)
= 5300
The balance in the bank after 5 years of 6.5% interest is $5,300.
