Answer:
21
Step-by-step explanation:
First, we would find 30% of 30, which would be 9. Then we would subtract 9 from 30 because we are decreasing it by 30%. That means the answer is 30-9, which is 21.
Answer:
4y = -x + 9
Step-by-step explanation:
2y = 8x - 6
Divide through by 2:-
y = 4x -3 so the slope of this line = 4
Slope of the line perpendicular to this = -1/4
So using the point/slope form of an equation of a line and the point (-3,3) we have:-
y - 3 = -1/4(x - -3)
y = -1/4x - 3/4 + 3
y = -1/4 x + 9/4 Multiply through by 4:-
4y = -x + 9

Answer:
7:45
Step-by-step explanation:
2 hours and 15 minutes can also be written as
2:15
if the movie takes 2:15 long and begins at 5:30, add both which is. 5:30+2:15
=7:45
therefore the movie ended at 7 hours and 30 minutes which can also be written as7:45
