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:
The correct answer is 25
Step-by-step explanation:
It is given a quadratic equation,
x² – 8x = 9
<u>To find the number to be added</u>
The given equation be x² – 8x = 9
here we have to add (b/2)² - the square of half the coefficient of x,
Here b = -8
(b/2)² = (-8/2)² = -4² = 16
Add both side with 16
x² – 8x + 16 = 9 + 16
(x - 4)² = 25
(x - 4)² = 5²
when you find x-intercept, you are finding the coordinate when y=0, hence sub y=0,
-8x-16=0
8x=-16
x=-2
Answer:
I believe 74
Step-by-step explanation:
There are 3 unidentified areas including Y
60+70+130
360-130=230
so now we know its not possible for it to above 100
so the only logical point 74
Step 1:
Subtract 3y from both sides
Step 2:
Divide both sides by -5
Answer:
x=3/5y + -22/5
