Answer:
540
Step-by-step explanation:
Amount of antifreeze in the 90% solution + amount of antifreeze in the 20% solution = amount of antifreeze in the 80% solution
0.90 x + 0.20 (90) = 0.80 (x + 90)
0.90 x + 18 = 0.80 x + 72
0.10 x = 54
x = 540
You need 540 gallons of 90% antifreeze solution.
Answer:
0.46
Step-by-step explanation:
42.78/m = 93
=> m = 42.78/93
=> m = 0.46
Hope my answer helps :)
Answer:
-1/6
Step-by-step explanation:
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
x+x+y.y.y = 2x+y^3 ( y cube)
So, The answer is (d)
