Answer:
a = 19
Step-by-step explanation:
-2(a + 3) = -4a + 32
-2a - 6 = -4a +32
<u> +2a +2a </u>
-6 = -2a + 32
<u>-32 -32</u>
-38 = -2a
divide by -2
<u><em>a = 19</em></u>
Answer:
1.07 hours
Step-by-step explanation:
14 miles = 1 hour
15 miles = x hours
Equal these two together
14 mi/1hr = 15 mi/xhr
Cross multiply
14 mi × x hr = 1 hr × 15 mi
I will stop using the units for now so it won't be as confusing
14x = 15
Divide both sides by 14 to isolate the variable
14x ÷ 14 = 15 ÷ 14
x = 1.07... hours
