Find the missing side

1) The missing length is 40.   2) The missing side is 30 .

Step-by-step explanation:

1)  9^2  + b^2 = 41^2

   81  +  b^2 = 1681

   -81                   -81

   b^2 =  1600

b= 40

2)  24^2 + 18^2 = c^2

 576  + 324 = c^2  

 900 =c^2

c= 30

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
