Answer:
it b 50
Step-by-step explanation:
hope this helped
24y*z^5/32y^2*z
24/32 = 3/4
y/y^2 = 1/y
z^5/z = z^4/1
Soo now that they are all simplified the answer is 3z^4/4y
Answer:
The students spent 135 minutes in lecture and 115 minutes in a lab.
Step-by-step explanation:
Let x and y be the respective amount of time students spent in lecture and lab.
x-20=y --- eqn 1
x+y=250 --- eqn 2
From eqn 1, x=y+20 --- eqn 3
Sub eqn 3 into eqn 2:
y+20+y=250
2y=230
y=115
Sub y=115 into eqn 3:
x=115+20
=135
∴x=135, y=115
So you just want to say 36/18 or 2.
So it's 2, or 200%.
