Answer: 65
Step-by-step explanation:
65 mph x 2 = 130 miles in 2 hours
520 total miles - 130 = 390
8 total hours - 2 hours = 6 hours
390 / 6 = 65 ave mph
.37 equals 37% and 37/100
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest
5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
