1- start with the original equation

x=2y+70

Let y =3x

x=2x 3x+70

simplify

x=6x+70

2-solve for x.

x=6x+70

Subtract 6x from both sides

x-6x=70

simplify x-6x to -5x

-5x=70

divide both sides by -5

x=- 70/5

simplify 70/5 to 14

x=-14

3- start with an original equation .

y=3x

Let x =-14

y=3x -14

simplify

y=-42

therefore

x=-14

y=-42

Each pepperoni slice is 78 of an inch long and costs $0.03. Exactly enough pepperoni slices are laid end to end to have a total
Leokris [45]

The total cost of these pepperoni slices is $1.92

<h3>What is the total cost of these pepperoni slices?</h3>

Each slice measures 7/8 of an inch. Here we have N slices, such that the measure of the N slices is 56 inches, then we have:

N*(7/8 in) = 56 in

Now we can find the value of N, the number of slices used:

N = (8/7)*56 = 64

And each slice costs $0.03, then the cost of the 64 slices is:

C = $0.03*64  = $1.92

The total cost of these pepperoni slices is $1.92
