Denise bought 5.2 pounds of rice for $5.29. using the unit rate, how much would 2 pounds of rice cost?

First step divide 5.29 by 5.2 so it's x/2
* each side by (5.2)(2)
(2)(5.29)=5.2x
divide each side by 5.2
2.034=x 
2.03=2 lb

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.
