Bennett was about 8 pounds when he was born in December. In March, Bennett was 15 pounds. What was Bennett's PERCENT INCREASE in weight from December to March?

87.50%

Step-by-step explanation:

The increase in weight between December was Bennett was given birth to and the following March is the difference between the weight now and prior weight i.e 15 pounds -8 pounds=7 pounds

The % increase in weight =the increase in weight/initial weight

the increase in weight is 7 pounds

the initial weight was 8 pounds

the % increase in weight=7/8=87.50%

The percentage increase in weight is 87.50%  rounded to two decimal places

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
