Answer:
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
Step-by-step explanation:
Equation:
acid + acid = acid
0.40x + 0.70(60-x) = 0.60*60
40x + 70*60 - 70x = 60*60
-30x = -10*60
x = 20 liters
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
Answer:
32 ; 20
Step-by-step explanation:
Middle section: 26
Sum of parallel lengths: 2 × 26 = 52
Ratio of the sides:
100% : 62.5%
8 : 5
5/(8+5) × 52
20
8/(8+5) × 52
32
Answer:
Either B or D is the answer
Answer:
y = -34
Step-by-step explanation:
Step 1
1/4 y + 9 = 1/2
1/4 + 9 - 9 = 1/2 - 9
1/4 y = -17/2
Step 2
4 * (1/4 y) = 4* (-17/2)
y = -34
Hope this helps!!
