Answer:
88 rolls of 2.
Step-by-step explanation:
By proportion that would be 220 * 20/50
= 220 * 0.4
= 88.
The Solution.
The given equation is

Substituting 11 for x, we can get the value of y.

Hence, the value of y is 18.
$36 because 20% of 45 is 9 and 45 - 9 is 36!
Answer:
y = 1/4 - 4
Step-by-step explanation:
This is because -4 is where the line intercepts with the y - axis while 1/4 is 1 up, over 3
Answer:
x = 20
Step-by-step explanation:
The three angles make up a straight line.
A straight line has 180 degrees.
x + 3x + 100 = x80 Combine
4x + 100 = 180 Subtract 100 from both sides
4x = 180 - 100
4x = 80 Divide by 4
x = 80/4
x = 20
