Marsha bought 1 pound 11 ounces of roast beef and 2 pounds 5 ounces of corned beef how much more corned beef did she buyes than roast beef

10 oz.

Step-by-step explanation:

We need to subtract the roast beef quantity from the corned beef quantity:

2 pounds 5 ounces - 1 pound 11 ounces  

Think: 1 pound = 16 ounces, so

2 pounds 5 ounces = 2 x 16 ounces + 5 ounces = 32 ounces + 5 ounces = 37 ounces

1 pounds 11 ounces = 1 x 16 ounces + 11 ounces = 16 ounces + 11 ounces = 27 ounces

37 ounces - 27 ounces = 10 ounces

Hope this helps you!

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
