Write an English phrase that would translate into the following mathematical expression.
kenny6666 [7]

Answer:

B. 8 times the difference of a number <em>z</em> and 6

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Translate (z - 6)

<em>z </em>= a number <em>z</em>

- = difference

6 = six

(z - 6) = The difference between a number <em>z</em> and 6

Step 2: Translate 8(z - 6)

(z - 6) = The difference between a number <em>z</em> and 6

Since we are distributing the 8, we are multiplying.

8 times the difference of a number <em>z</em> and 6
