A recipe that serves 6 uses 1 1/2 cups of flour. How many cups are needed to serve 15

3 3/4 cups

Step-by-step explanation:

You can make a proportion and solve. 1 and 1/2 equals 1.5. Next make the proportion. Proportion= 1.5/6 to x/15. then multiply 1.5 times 15 and then divide by 6.

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
