Answer: a = -3
Step-by-step explanation: First we distribute the -2 to a and -3 to get -2a+6=12, then subtract 6 on both sides, -2a=6, finally divide by -2 on each side to get a = -3.

Amy wants to enlarge a rectangle with sides 9 and 12 inches. If
the shorter side of the new rectangle is 135 inches, how long will
the longer side be?
Answer: the longer side will be 180 inches.
Step-by-step explanation:
We are given that the rectangle has the sides, 9 inches and 12 inches . This means that the shorter side is 9 inches.
It has to been enlarge, meaning that it has gotten bigger to 135 inches.
This also means that it was multiplied by a number to get 135.
So divide 135 by 9 to find the number it was multiplied by, and multiply that number by 12 to find the length of the longer side.
135 / 9 = 15
12 * 15 = 180
This means the larger side is 180 inches.

12. Water is being pumped into a pool at a constant rate of 8.25 gallons per minute. If the pool contained 1250
gallons of water initially, write a function for the number of gallons of water, g(t),in the pool after t minutes
of pumping water into the pool.
Answer:
[tex]g(t)=8.25t+1250[/tex]
Step-by-step explanation:
You can input any value for t, and that would give you the amount of water pumped in. Then, the +1250 represents the initial 1250 gallons that are in the pool.

A fraction represents a part of a whole.40/70, 21/70 are the same fractions like 4/7 and 3/10 with same denominator.
What is a fraction?A fraction represents a part of a whole
We need to write 4/7 and 3/10 with the same denominator
The given fractions are 4/7 and 3/10
in 4/7
If numerator and denominator is multiplied with 10
4/7*10/10
we get
40/70
i.e 4/7=40/70
Now
in 3/10
If numerator and denominator is multiplied with 10
3/10*7/7
we get
21/70
i.e 3/10=21/70
Therefore 4/7=40/70 and 3/10=21/70 are two fractions with same denominator.

What is the slope for (-1,2) and (1,16)
Answer:
The slope is 7.
Step-by-step explanation:
(-1, 2) and (1, 16)
Slope is found using the following formula:
(y₂ - y₁) / (x₂ - x₁)
First, let's label the coordinates (these can be in any order, as long as the second numbers in each coordinate are in the y slots and the first numbers are in the x slots:
y₂: 16
y₁: 2
x₂: 1
x₁: -1
Now, substitute into the original formula:
(y₂ - y₁) / (x₂ - x₁)
(16 - 2) / (1 - (-1))
Simplify
(14)/(2)
7
The slope is 7.

Vanessa and Zack are playing a game where the player with the lower score wins. At the end of the game, Vanessa has a score of Negative 3 and Start Fraction 5 over 8 EndFraction and Zack has a score of Negative 3 and two-thirds. Which statement explains who won?
Answer:
Zach won
Step-by-step explanation:
For UA to be able to know the lowest score, we can express their score as percentage.
Vanessa score = -3 5/8 = -29/8
Express in percentage
= -29/8 × 100
= -2900/8
= - 362.5%
Zack score = -3 2/3 = -11/3
Express as percentage
= -11/3 ×100
= -1100/3
= -366.7%
Since the person with lowest score wins, hence Zack won. Note that the highest negative value serves as the lowest score.
