SAT question c5e38487 (Linear Equations In Two Variables)

Question

A chemist combines water and acetic acid to make a mixture with a volume of 56 milliliters (mL). The volume of acetic acid in the mixture is 10 mL. What is the volume of water, in mL , in the mixture? (Assume that the volume of the mixture is the sum of the volumes of water and acetic acid before they were mixed.)

College Board · Accepted Answer

The correct answer is 46. The correct answer is 46 . It's given that a chemist combines water and acetic acid to make a mixture with a volume of 56 milliliters (mL) and that the volume of acetic acid in the mixture is 10 mL. Let x represent the volume of water, in mL, in the mixture. The equation x + 10 = 56 represents this situation. Subtracting 10 from both sides of this equation yields x = 46 . Therefore, the volume of water, in mL, in the mixture is 46 .
