About 20% of the time you sleep is spent in rapid eye movement (rem) sleep, which is associated with dreaming. if an adult sleeps 7 to 8 hours, which inequality shows how much time, in hours, is spent in rem sleep?
1.4 < h < 1.6
35 < h < 40
0.35 < h < 0.4
14

The answer should be 1.4<h<1.6

Step-by-step explanation:

Multiply 7 and 8 by 0.2 to find out what 20% is. 7*0.2=1.4 and 8*0.2=1.6. So it should be at or between those two numbers making the inequality 1.4<h<1.6

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
