shalynn is digging holes for plants. she digs 5 holes per hour. there were 7 holes completed before she began digging. which equation represents the number of holes, r, after shalynn digs for x hours? a 5r + 7 = x b 5x + 7 = r c 7r + 5 = x d 7x + 5 = r

shalynn is digging holes for plants. she digs 5 holes per hour. there were 7 holes completed before she began digging. which equation represents the number of holes, r, after shalynn digs for x hours? a 5r + 7 = x b 5x + 7 = r c 7r + 5 = x d 7x + 5 = r

Answer

Explanation:

Step1: Calculate the number of holes dug in x hours

Since she digs 5 holes per hour, the number of holes dug in x hours is (5x).

Step2: Find the total number of holes

There were 7 holes before she started. So the total number of holes (r) is the sum of the initial 7 holes and the holes dug in x hours. So (r = 5x+7).

Answer:

B. (5x + 7=r)
