James needs 70 liters of 50% antifreeze. He has 30% antifreeze and 80% antifreeze available. How many liters of the 30% antifreeze and how many liters of the 80% antifreeze should he mix to make the 50% antifreeze?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

- (2, -7)

- lines r and s and lines t and u must be parallel

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
