Answer:
81% of the balls are red
Step-by-step explanation:
If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball
18 red + 4 blue = 22 balls part (a)
18/22 = 9/11 part (b) simplify
9/11 * 100 part (c) multiply the fraction by a hundred to get the percentage
81.81 ~ 81% part (d) solve
Answer:
36+2w=96
2w=96-36=60
w=60/2=30
Step-by-step explanation:
perimeter is 96, that means length + length + width + width = 96.
say l is length and w is width.
since we know length is 18, 18+18+width+width = 96
36+2w=96
2w=96-36=60
w=60/2=30
(8)(-4.5) is not equivalent because 8 times -4.5 results in negative value
