Answer:
$1.89
Step-by-step explanation:
This is a simple unit-rate proportion. We're trying to find the rate of 1 gallon to unknown money. To get 1 gallon, we have to divide it by 13, because that's the total gallons we start with.
13 = 24.57
/13
_________
1=24.57
Whatever we do to one side of the equation, we have to do to the other, so we divide 24.57 by 13, too.
1 = 24.57
/13
_________
1=1.89
For every gallon of gas, you pay 1.89 dollars.
Hope this helps!

Step-by-step explanation:
Goal: Find x and solve the equation
1) Since they are parallel angles, you can move QXY up to SQR.
Note: I don't really know how to explain this... Hope this is enough.
2) Set up the equation and solve
4x+40+2x-10 = 180
6x+30=180
6x = 150
x = 25
3) Solve the PQS equation
4x+40
4(25)+40 (Substitute x here.)
100+40

Ben earns $940 for working 80 hours on his job
a. Write an equation to represent the amount of pay Ben will earn for any number of hours worked.
b. Use your equation to determine how many hours Ben worked if he earned a total of $411.25
Answer:
5.1 or 5.140625 (The equation would be 411.25/80=5.140625)
Step-by-step explanation:
80x=940
x=11.75
80x=411.25
x=5.140625
The equation would be
411.25/80=hours
hours =5.140625
And if you're supposed to round your answer it'd be
5.1

What characteristics are needed to determine that two polygons are similar?
The quadrilateral PQRS in the diagram is a parallelogram. Which of the following statements would be true if P′Q′R′S′ is the image of PQRS after applying a dilation centered at a point O with scale factor 3?
P′Q′=PQ
P′Q′=3PQ
PQ=3P′Q′
Cannot be determined from the information given
A. Because changing the size of a polygon doesn't change its angles, it would stay at 82°.
B. The characteristics needed to prove they are similar are just their angles.
C. The scale factor is 3, so P'Q'=3PQ.
Determine whether each equation has one solution, no solution, or infinitely many solutions
3/2(2x+6)=3x+9
3x+5=3(x+5)
x+4x+4=3(2x-1)
6x+4x+1=2(5x+1)
Answer: Let's solve each equation step by step to determine the number of solutions:
3/2(2x+6)=3x+9
First, we distribute the 3/2 on the left side:
3x + 9 = 3x + 9
Subtracting 3x from both sides, we get:
9 = 9
This means that the equation is an identity and is true for all values of x. Therefore, it has infinitely many solutions.
3x+5=3(x+5)
Expanding the right side:
3x + 5 = 3x + 15
Subtracting 3x from both sides, we get:
5 = 15
This is a contradiction, so the equation has no solution.
x+4x+4=3(2x-1)
Simplifying the left side:
5x + 4 = 6x - 3
Adding 3 to both sides and subtracting 5x from both sides, we get:
7 = x
Therefore, the equation has one solution, x = 7.
6x+4x+1=2(5x+1)
Simplifying both sides:
10x + 1 = 10x + 2
Subtracting 10x from both sides, we get:
1 = 2
This is a contradiction, so the equation has no solution.

4x-18 = x/2 + 6
Step-by-step explanation:
so on the lhs we have 18 less than 4 times a number which u can write as 4x-18. On the rhs we have 6 more than half of x which will give you x/2 + 6.

Emilio has a gift card with $250 on it. He uses the gift card to buy 5 DVD's.
Adam has a gift card with $150 and uses it to purchase 4 DVD's.
If they both now have the same amount left on their gift cards, how much did each DVD cost?
Answer: Each DVD cost $100
Step-by-step explanation:
So it's a system of equations, where x = DVD price and y = remainder...
250 - 5x = y
150 - 4x = y
Now let's find x by making the y's cancel out.
In order to do this, multiply one equation by -1!
-250 + 5x = -y
150 - 4x = y
Which equals to...
-100 + x = 0
Add 100 to both sides...
x = 100
MEANING that each DVD cost $100. Quite pricey if you ask me!

The following angles are supplementary to each other.
m∠A = (3x + 21)° and m∠B = (6x − 21)°
Determine x.
10
20
36
60
Answer: X=20
Step-by-step explanation: Supplementary angles, by definition, add up to 180.
(3x + 21) + (6x - 21) = 180
3x + 6x + 21 - 21 = 180
9x = 180
9x/9 = 180/9
x = 20
x = 20 . Option B is correct.
What are supplementary angles?Two angles are supplementary to each other if their sum is equal to 180°.
Given,
∠A = (3x + 21)°
And ∠B = (6x − 21)°
Also, ∠A and ∠B are supplementary angles.
Therefore, ∠A + ∠B = 180°
(3x + 21)° + (6x − 21)° = 180°
(9x + 0)° = 180°
Hence, x = 20.
