Let r = 3. what is the value of (10 + 17) ÷ r?
a. 9
b. 17
c. 27
d. 30

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
