Answer: how many square feet are there? multiple each square foot by 2
Step-by-step explanation:
V30% mixture + v100% mixture = v60% mixture
0.3(10-x) + x = 0.6(10)
3 - 0.3x + x = 6
0.7x = 6 - 3
0.7x = 3
x = 3/0.7
x = 4.286 quarts
2y/5 is the same thing as 2/5 times y so
14=2/5(y) then you divide both sides by y and you get
14/y=2/5 then from there multiply both sides by 1/14 to get
y=0.03
