8x + 2 - 6x (Subtract the numbers)

2x + 2 (Combine like terms)

2 (x + 1)  (Common factor - Factor by grouping twice)

6) <em>2y-6+5y+9</em>

2y + 3 + 5y (Add the numbers)

7y + 3 (Combine like terms)

7) <em>3x+8+4x-9</em>

3x - 1 + 4x (Subtract the numbers)

7x - 1      (Combine like terms)

8) <em>9y+16-12y+24</em>

16c - 16 (Combine like terms)

16 (c - 1)   (Common factor - Factor by grouping twice)

11) <em>5(2x + 3) (This one was a bit blurry, I am assuming that's a addition sign.)</em>

10x + 15 (Distribute)

12) <em>5(-2x+3)</em>

-10x + 15 (Distribute)

Hope this helps!

A rectangular prism has a top face with an area of 20 ft2 and a height of 5 ft. What is the volume of this rectangular prism? Th
kkurt [141]

Answer:

the volume of the rectangular prism is 100 ft³  

Step-by-step explanation:

Given;

area of top face of a rectangular prism, A = 20 ft²

height of the rectangular prism, h = 5 ft

Volume of the rectangular prism =  Area of top face x height of the rectangular prism

Volume of the rectangular prism = A x h

Volume of the rectangular prism = 20 ft² x  5 ft

                                                       = 100 ft³

Therefore, the volume of the rectangular prism is 100 ft³

A pile of coins, consisting of quarters and half dollars, it worth $11.75. If there are 2 more quarters than half dollars, how m
lord [1]
Let the number of half dollars be x,

number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17

There are 17 quarters and 15 half dollars.
