Sarah went to the grocery store and bought 4 loaves of bread and 1 gallon of milk for $12. the next week, sarah bought 2 loaves of bread and 3 gallons of milk for $13.50. which system of equations below can be used to determine the cost of one loaf of bread (b) and one gallon of milk (m)? a 4m × b = $12 2m × 3b = $13.50 b 4b × m = $12 2b × 3m = $13.50 c 4m + b = $12 2m + 3b = $13.50 d 4b + m = $12 2b + 3m = $13.50

D.

Step-by-step explanation:

You want to add the totals for bread and milk together, you would not want to multiply.

Also, there were 4 loaves of bread bought, so 4m would be incorrect.

By process of elimination, we see that answer D is correct!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
