Answer:
x = 7 (i think..)
Step-by-step explanation:
-3 (4 - 3x) = 5x + 16
* multiple -3 to each number in the parenthesis
-12 + 9x = 5x + 16
* add 12 to both sides to cancel it and combine like terms on the other side
9x = 5x + 28
* subtract 5x from both sides to cancel it out and combine like terms
4x = 28
* divide 4 from both sides to get x alone
x = 7

Step-by-step explanation:
Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?
Distance = 3/4 of a mile
Time taken on Monday = 1/6 of an hour.
What is Selma's unit rate in miles per hour for Monday's run?
Unit rate in miles per hour for Monday's run = distance ÷ time taken
= 3/4 ÷ 1/6
= 3/4 × 6/1
= (3 * 6) / (4 * 1)
= 18/4
= 4.5 miles per hour
Unit rate in miles per hour for Monday's run = 4.5 miles per hour
