r = 3.25
Step-by-step explanation:
Solve for r:
0.5 (r + 2.75) = 3
Multiply both sides of 0.5 (r + 2.75) = 3 by 2:
2*0.5 (r + 2.75) = 2*3
2*0.5 = 1:
1 (r + 2.75) = 2*3
2*3 = 6:
1 (r + 2.75) = 6
Multiply both sides of 1 (r + 2.75) = 6 by 1:
1*1 (r + 2.75) = 1*6
1*1 = 1^2:
1^2 (r + 2.75) = 1*6
1^2 = 1:
1 (r + 2.75) = 1*6
1*6 = 6:
r + 2.75 = 6
Subtract 2.75' from both sides:
r + (2.75 - 2.75) = 6 - 2.75
2.75 - 2.75 = 0:
r = 6 - 2.75
6 - 2.75 = 3.25:
Answer: r = 3.25
