Answer:

My Answer: <u>33.95</u>

Step-by-step explanation:

x - 13.75 = 20.2

so because it is subtracting we have to add.

x - 13.75 + 13.75 = 20.2 + 13.75

when added, x will cancel out, and we will be left with the answer.

x = 33.95

The results of a car race are shown. How much faster did Evans drive per lap than loza?
Lelechka [254]
Evans finishes 42 laps in 96,6 mins and Loza finished 38 laps in 102,6 mins

Evans. 96,6÷42= 2,30 mins
Loza . 102,6÷38= 2,70 mins

2,70 mins - 2,30 mins
= 40 secs and Evan is faster with 40secs in each lap.

Hello! First we should note that the shape of the figure can be broken down into two rectangular prisms, so that the expression will look like:

Volume = (w • h • l) vertical rectangular prism + (w •h • l) horizontal rectangular prism

Thus Volume = (7 • 3 • 3) + (9 • 3 • 4)
