PLEASE SOLVE THIS FOR ME
R/2+3= -11
subtract 3 from both sides, then multiply each side by 2
On the fastest speedways, some some drivers reach average speeds of 2 miles per minute. Write a formula that gives the number of miles M that such a driver would travel in x minutes. How far would this driver travel in 33 minutes
distance=rate*time
distance=2mi/min * 33 min=66miles
To solve the equation r/2 + 3 = -11, we need to isolate the variable r.
Step 1: Subtract 3 from both sides of the equation:
(r/2) + 3 - 3 = -11 - 3
r/2 = -14
Step 2: Multiply both sides by 2 to get rid of the fraction:
2 * (r/2) = -14 * 2
r = -28
Therefore, the solution to the equation r/2 + 3 = -11 is r = -28.
