mindy:  v=40in

matt:     v=40cm

Step-by-step explanation:

--the formula for volume is V=LWH or Volume=Length×Width×Height.

--basically just v=5×2×4      v=10×4     v=40

you don't need to convert either to be the same because it doesn't tell you to, just make sure you put the right labels on each answer

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
