Seven times the sum of a number and 2 is equal to 9

Answers

Let x = a number

7(x + 2) = 9

Then we solve for x. First, distribute:

7x + 14 = 9

Subtract 14 from both sides:

7x = -5

Divide by 7 on both sides:

$x= (-5)/(7)$

The number is then -5/7.

Sybrina jogged 2 miles in 30 minutes. At this rate, how far would she jog in 90 minutes?At what rate did she jog each hour?

Answers

6 miles in 90 minutes and 4 miles per hour. 30 times two is 60 min so 2 miles times two is 4 miles.

another 30 min is 90 min and another two miles is 6 miles.

2miles per 30min - 2 to 3
90/30=3x2=6
6miles in 90min
She was jogging @ a 1mile per 15min but each hour it was 4mile per hour
