Answer: Im sorry i dont really get the question :/
Step-by-step explanation:
Speed = 416 miles / 8hrs = 52 miles per hr.
Distance = Speed * Time = 52 * 22 = 1144miles
Substitute x for 3 & y for -2
22 - 2(-2) = 26
3(2) + 2(-2) = 2
Ella has 0.5 lbs of sugar. 75% syrup
Percent of mass = 
Let the mass of solution is x
Given mass of solute = 0.5
percent of mass = 75
75 = 
75x = 0.5 * 100
75 x = 50
x = 0.67
Mass of solution = 0.67
Mass of water = mass of solution - mass of solute (sugar)
= 0.67 - 0.5 = 0.17
So 0.17lb of water is added with 0.5lb of sugar to get 0.67lb of solution.
