Answer:
7
Step-by-step explanation:
you subtract 84 on both sides and then you end up with -6x>-42 divide -6 on both sides and you have 7
Answer: x < 7
Step-by-step explanation:
84 - 6x > 42 First subtract 84 from both sides
-84 -84
-6x > -42
x < 7 Remember when dividing both sides of an inequality by a negative number, the sign flips and becomes its opposite.
In this case > will become <.

which graph represents y=3x+2
Step-by-step explanation:
The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.
For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).
We are between Options B and C.
In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.
In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.
Since we want 3 as the slope,
The answer is Option C.
The graph C represents y=3x+2

How many cubic meters of water are required to fill a rectangular swimming pool 15m long and 10 m wide which is 2m deep throughout.How many liters is that?
Answer:
300,000 liters
Step-by-step explanation:
Let us have the measurements in cm
100 cm = 1 m
so the measurements are multiplied by 100
we have this as;
1500 by 1000 by 200
The volume is the product of the 3
This is :
1500 * 1000 * 200 = 300,000,000 cm^3
Mathematically, 1 liter = 1000 cm^3
300,000,000 cm^3 will be ;
300,000,000/1000 = 300,000 liters
can someone please help me graph y=2/3x-4
Answer:
Look at the picture attached.
Step-by-step explanation:
Your x-intercept is 6 and your y-intercept is 4, that is where your 2 points will go. According to the slope, you should go up 2 and over 3, if you don't want to find the x-intercept. Then you would just plot the y-intercept which is 4, and then go up 2, over three and plot the next.

A tax of 7% was added on to the cost of a meal. If the tax paid was $1.40, what was the cost of the meal?
Answer:
The cost of meal is: $20
Step-by-step explanation:
Given
Percentage of tax = 7%
Also given that the amount of tax is $1.40
Let x be the price of meal
Then the tax will be 7% of x
It can be written mathematically as:
[tex]1.40 = 7\%\ of\ x[/tex]
We will simply solve this equation to get the price of meal
So,
[tex]1.40 = 0.07*x\\x = \frac{1.40}{0.07}\\x = 20[/tex]
Hence,
The cost of meal is: $20
The cost of a game g with 7% sales tax can be represented by the expression g + 0.07g. Simplify the expression. Then determine the total cost of the game after sales tax if the original price is $52. (Remember that the coefficient of g is 1).
Answer:
$58.64
Step-by-step explanation:
The total cost of a game g with 7% sales tax can be represented by the expression
g + 0.07g
From the above question,
g = Original price of the game = $52.
The total cost of game g =
$52 + 0.07 × $52
$52 + $3.64
= $58.64

All of the following are equivalent except____.
4y
(4)(y)
4•y
4+y
Answer:
All the options are equivalent except;
4 + y
Step-by-step explanation:
The question relates to the number of ways the operation of a multiplication operation can be represented algebra
1) The coefficient of a variable is a multiplier of the variable
Therefore;
4y = 4 × y
2) When given two numbers or variables in a mathematical expression that are separated by parenthesis, then it is an indication that the two numbers are meant to be multiplied
Therefore;
(4)(y) = 4 × y
3) The dot symbol, '·', placed between two numbers, a number and a variable or two variables, is a representation of multiplication of the two quantities
Therefore;
4·y = 4 × y
However, multiplication, and addition are different mathematical operations that produce different results when applied;
Therefore;
4 + y ≠ 4 × y.
A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?
Answer:
The jet will cover 2585 miles in 11 hours.
Step-by-step explanation:
Given that:
Distance travelled by jet in 2 hours = 470 miles
Speed of jet = [tex]\frac{Distance}{Time}[/tex]
Speed of jet = 470/2
Speed of jet = 235 miles per hour
Time = 11 hours
Distance travelled in 11 hours = Speed * Time
Distance = 235 * 11
Distance = 2585 miles
Hence,
The jet will cover 2585 miles in 11 hours.

Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?
A.
5 miles
B.
158 miles
C.
300 miles
D.
453 miles
Answer: D. 453 miles .
Step-by-step explanation:
Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.
At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour [1 hour = 60 minutes],
Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]
[tex]=458-5=453\ miles[/tex]
Jessica is 453 miles from her home after 5 minutes she began returning home.
Hence, the correct option is D. 453 miles .

Answer: The answer is 0.20
Step-by-step explanation: To find a scale factor all you need to do is find the ratio of a side on the scaled shape to its corresponding side on the original figure. We know the bottom of the scaled figure is 0.5 and the same side on the original rectangle was 2.5 so we can just divide like so...
0.5/2.5 = 0.2 which is our correct answer. I hope this has been of use to you :) If you have any other questions please do not hesitate to ask!

Which answers would be possible first steps?
Answer:
e i think or find out what x =
solve using substitution
-5x+7y=-5
y=-5
x=?
So if you solve for x using the first equation, you get: x = 5y - 5.
From there you can plug that into the second equation which would give you:
7y-5y+5=-23
Simplifying from that point, you get y = -9.
Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.
