Grace got 22 questions right. 88% = 0.88 or 88/100 If you reduce 88/100, it becomes 44/50 or 22/25. To check your answer do 22/25 * 100 on a calculator. Sorry I'm bad at explaining.

Answer:

w=3 h=4

Step-by-step explanation:

14=2w+2h w=(3/4)h

substitute

14=2(3/4)h+2h

distribute

14=1.5h+2h

simplify

14=3.5h

divide both sides by 3.5

4=h

plug into original equation

w=(3/4)4

w=3

Stephanie is 62 inches tall. Her brother is t inches shorter than she is.

Law Incorporation [45]

Answer: 62 - T

Step-by-step explanation:

I think it is 62 - T because Stephanie is 62 inches and it says that her brother is shorter which I believe it means that you have to subtract.

Rationalize the denominator of sqrt -9 / (4-7i) - (6-6i) ...?

Colt1911 [192]

√(- 9 ) / (( 4 - 7 i ) - ( 6 - 6 i )) = 3 i / ( 4 - 7 i - 6 + 6 i ) =
= 3 i / ( - 2 - i ) = - 3 i / ( 2 + i ) =
$= \frac{-3i}{2 + i}* \frac{2 - i}{2 - i}= \\ = \frac{-6i+3i ^{2} }{2- i^{2} }= \\ = \frac{-3-6i}{2+1}= \frac{-3-6i}{3}=$
= - 1 - 2 i
