Question

Eight is 5 less than twice the number r

Answer 1

r = 6.5

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

Answer 2

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