Erik has 8 sacks of flour. Some of his sacks weigh 3 pounds, and the others weigh 7 pounds. The total weight
of his flour is 36 pounds. How many 7-pound sacks does
he have?

You take the two and make the equations

x+y=8

3x+7y=36

(x=3 pounds;y=7 pounds)

then you plug numbers in.. (v)

Step-by-step explanation:

3(5)+7(3)=36

15+21=36

Step-by-step explanation: 3 seven pound bags and 5 three pound bags

7+7+7=21. 3+3+3+3+3=15. 21+15=36

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

it’s supposed to be -4+45=41
