Eight is 5 less than twice the number r

r = 6.5

Step-by-step explanation:

Set up an equation:

"Eight is" means 8 equals "5 less than" means minus 5 "twice the number r" means r times 2

Therefore, the equation is 8 = 2r - 5

Solve:

8 = 2r - 5

Add 5 on both sides:

8 = 2r - 5

+5 + 5

13 = 2r

Divide by 2 on both sides:

13 = 2r

/2 / 2

6.5 = r

I think the answer is 1.5 but I'm not 100%sure
