Answer:
1.52
Step-by-step explanation:
You can convert all the numbers into a fraction to solve the expression.
4/5 is equal to 80/100, and 0.35 is equal to 35/100. (37/100 is left as it is.)
80/100 + 35/100 + 37/100 = 152/100.
When simplified and converted into a decimal, the answer is 1.52.
Answer:
5.29
Step-by-step explanation:
Let x = 30% y=16%
We need 5 liters of 27.2% acid
A) x + y = 5
B) .30 x + .16y = 5 * .272
Multiplying A by -.30
A) -.30 x - .30y = -1.5 then adding to B
B) .30 x + .16y = 1.36
-.14y = -.14
y = 1 liter 16%
x = 4 liters 30%
