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

Please help me solve this please
Tems11 [23]

Answer:

x = 8

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to the exterior angle that's supplementary to the third interior angle:

7x + 6 + 22 = 9x + 12 add like terms

7x + 28 = 9x + 12 export like terms to the same side of the equation

28 - 12 = 9x - 7x

16 = 2x divide both sides by 2

8 = x

Which transformation occurred?
nikdorinn [45]
The x coordinate remains the same.
 The Y coordinate changes from a positive number to a negative number.

This means that the figure is reflected across the X axis because positive Y values are above the X axis and negative Y values are below the X axis.

The answer is D.
