Answer:
24u + 10
Step-by-step explanation:
first rearrange the terms
4(10+6u)
4(6u+10)
then distribute the 4
4(6u) = 24u
4(10) = 10
then you get 24u + 10
Answer:

Answer:
x + y = 500
215x + 615y = 187,500
Step-by-step explanation:
The first equation can show the amount of land. The farmer has 500 acres to plant corn, x, and cotton, y.
x + y = 500
The second equation can show the cost. The farmer has $187,500 to invest when corn costs $215 per acre and cotton costs $615 per acre.
215x + 615y = 187,500
The system of equations is
x + y = 500
215x + 615y = 187,500
