Answer:

Step-by-step explanation:

Like your other question, let's break it down systematically

6x + 9y - 9(6x - 3y + 8z)

Use the distributive property

6x + 9y - <u>9(6x - 3y + 8z)</u>

6x + 9y - 54x - 27y + 72z

Match like terms

6x - 54x = -48x

9y - 27y = -18y

72z - 48x - 18y

Klio2033 [76]

Answer:

22 miles

Step-by-step explanation:

time must be in hours, hence

15 minutes = $\frac{15}{60}$ = $\frac{1}{4}$ hour

distance = 88 × $\frac{1}{4}$ = $\frac{88}{4}$ = 22 miles
