Sally was riding her bike and figured out her speed was 12ft/sec how fast was that in miles/ hour

There are 5280 feet in a mile, and 3600 seconds in an hour. Multiply 12 by 3600 to cancel out the seconds and get it into ft/hour, then divide by 5280 to get it into mph. The answer would be 8.18 mph.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
