Answer :
27.5 minutes
Steps:
1) put into fraction form:
160/20 = 220/x
2) simplify:
160/20 = 8/1
3) cross multiply:
8 • x = 8x
220 • 1 = 220
4) divide on both sides:
8/8 = crosses out
220/8 = 27.5
C is your answer by the way
The little marks on the sides tell that this is a equilateral triangle, each angle measures 60 degree.
2y=60
y=30
25x-15=60
25x=75
x=3
Answer:
18
Step-by-step explanation:
just replace the x and y with the given values like so (3)4+0.5(4)3=x and solve for the new x value
The answer is 87 positive
