Answer:

C. −12

Step-by-step explanation:

9 − 4x = 57

Subtract 9 from each side

9-9-4x= 57-9

-4x = 48

Divide by -4 on each side

-4x/-4 = 48/-4

x = -12

Please help will give 20 points to right answers (will give brainliest to very first correct answer) Tom walks 3.2 km every morn

nignag [31]

For this case we have the following conversions:
$1 mile = 1,609 km

1 mile = 5,280 feet$
We must apply the conversions to move from kilometers to feet.
We have then:
$(3.2) * (1 / 1,609) * (5280) = 10500.93226
$
Rounding off we have:
10501 feet
Answer:
there are 10501 feet in 3.2 km
