Answer:

The answer would be d(c(x)) = .60x - 5

Step-by-step explanation:

In order to write an equation for d(c(x)), start with the d(y) equation.

d(y) = .80y - 5

Now input the c(x) equation in for y and then solve.

d(c(x)) = .80(.75x) - 5

d(c(x)) = .60x - 5

Step-by-step explanation:

1) -4x + 9x = 5x\\\\2) 6y -8y = -2y\\\\3) -7x+x = -6x\\\\4) 9y-y = 8y\\\\5) -5x-5x = -10x\\\\6) 3y-7y = -4y\\\\7) -x-8x+7 = -9x +7\\\\8) y-2y -3 = -y -3\\\\9) 5+5x-4x = 5 + x\\\\10) 3y-6 +7y-4y = 6y -6\\\\11) -9x-5-8+x = -13 -8x\\\\12) 6-y+5y-6y = 6 -2y\\\\13) 3x-8y+2x-5-5y = 5x -13y -5\\\\14)-9x +3 +2x-9y-8 = -7x -9y -5\\\\15) 5 +6x -3y +x +8y = 7x +5y+5\\\\16) -4x -4 +x -2y +7x = 4x -2y -4\\\\17) -8x +7y-x-6y+4x = -5x +y\\\\18) x+5-2x+3y-y=2y-x+5\\\\19) 9x-3y+7-4x+y-3 = 5x-2y+4\\\\

20) -x-3+5x+6y+8x-9\\\\21) 4x-4-8y+8-5x+1 = -x-8y+5\\\\22) 3x-x+6y-4x-y = -2x+5y\\\\23) 2x+2y-x-y-7+5y = x+6y-7\\\\24) 6x-8x-4y -x+5y-2y = -3x-y\\\\

miskamm [114]
Lets look at the info we have:-

6 friends
Pay $90 and receive $42 in change.

Question:-

How much does each friend pay?

To answer this first we nee to find out how much they paed in total. lets do that 1st:-

90 - 42 = 48
They paid $48 for the gift.

CHECK OUR WORK:-

48 + 42 = 90
We were RIGHT!!

Now lets divide to find out how much each person paid:- 

48 ÷ 6 = 8
Each friend pays $8.

CHECK OUR WORK:-

8 × 6 =  48
We were RIGHT!!

So, each friend pays $8 for the gift.

Hope I helped ya!! xD
