Answer: m=-4
Step-by-step explanation:
-4(m+6)=-8
-4m-24=-8 (distribute)
-4m=16 (add 12 to both sides)
m=-4 (divide by -4 to both sides)

Answer:
0.7 seconds
Step-by-step explanation:
You have to subtract both lap times, but before doing so you need to know what 2/5 is in decimal form. To do so, you must do 2 divided by 5, getting 0.4 seconds as it's a fraction converting to decimal. This means Fam swam 29.4 seconds, which instead of 2/5, you have 0.4 as your converted answer, so you would substitute it after 29. Then, you would do 29.40 subtracted by 28.7 and get 0.7 seconds as your answer to find out the difference of their swim times.
Carl needs 1/2 pair of jeans per day and 1 shirt per day. If he does no laundry, he will require
(1/2 jeans/day)*(14 days) = 7 jeans
(1 shirt/day)*(14 days) = 14 shirts
Carl needs to pack 7 pairs of jeans and 14 shirts.
