Answer:
Eric practiced the piano for 2 hours this week
Step-by-step explanation:
If it tells us that Eric spent 1/4 of the time playing the piano and all the time he practice this week was 8 hours, then we have to multiply the 8 hours by 1/4
p = time he practice piano
p = 8h * 1/4
p = 2h
Eric practiced the piano for 2 hours this week
Answer:
8-7x
Step-by-step explanation:
3x2-7x+2
6-7x+2
8-7x
First you know that at 6 it was 75 degrees. Now it’s noon and the temperature is 18 degrees warmer. So when you add 75 and 18 you get 93 degrees. When the storm rolls in at 4 it says that your temperature dropped 21 degrees. So you need to subtract 21 from 93 (93-21) which will get you at 72 degrees at 4pm
