Afarmer plants corn and wheat on a 180-acre farm. the farmer wants to plant three times as many acres of corn as wheat. write a system of linear equations that represent this situation. how many acres of each crop should the farmer plant?

C=number of acres of corn
w=number of acres of wheat

total is 180 acres

c+w=180

wants to plant 3 times as many corn as wheat
c=3w

subsitute 3w for c in other

c+w=180
3w+w=180
4w=180
divide boh sides by 4
w=45

sub back
c=3w
c=3(45)
c=135

135 acres of corn and 45 acres of wheat

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
