Write and solve an equation for the situation. the sum of 7 and u is 14. a. 7 + u = 14; u = 7 b. 14 + 7 = u; u = 21 c. 7 + u = 14; u = 8 d. 7 + 14 = u; u = 21

A. 7 + u = 14 ; u = 7

Step-by-step explanation:

is means equal so that means that the 14 goes behind the equal sign, and the sum of 7 an u means add them.

To find the answer subtract 7 from 14 and when you do you get 7

A

Step-by-step explanation:Because it says the sum of 7 and u is 14 and means to add and sum is the total so it is 7 + u = 14

the answer is 31.27mph
