Hello! So Angie reads 60 pages in 2 hours, without the TV on. 60/2 is 30. She reads 30 pages an hour without the TV on, and 24 pages with the TV off. To find the percent of her reading rate with the TV on instead of off, we can just divide both of the reading rates. 24/30 is 0.8. Multiply that by 100 and you get 80% in percent form. There. Angie's reading rate with the TV on is 80% of her reading rate with the TV off. The answer is B: 80%.
Answer:
Step-by-step explanation:
y/4 - 4 = 3
Add four to both sides | y/4=7
We know that 7*4=28 so therefore y must be 28 | 28/4=7
7=7
Therefore y=7
Answer: -3x+y=-4
Step-by-step explanation:
Standard form is Ax+By=C. In y=Mx+b form, it would be y=3x-4. To put it into standard form you subtract 3x from both sides. So then you have -3x+y=-4.
Well, the rooms require 8 cans of paint, and since you spilled some, you have 1 can, so you would have to buy 7 cans of paint.
