Answer:
The answer is a and e
Step-by-step explanation:
The equation is: 27.46 = 1.95x + 2.50
The answer is 12.8
There are 12 inches in one foot. If it rains 2 inches per hour and we need one foot we need to look for a number that can be multiplied by 2 to get 12.

Answer:
4.5 % alloy
Step-by-step explanation:
Let x = amt of 30% alloy
The resulting total is to be 25 oz, therefore:
(25-x) = amt of 5% alloy:
A typical mixture equation:
.30x + .05(25-x) = .20(25)
.30x + 1.25 - .05x = 5 .30x - .05x = 5 - 1.25
.25x = 3.75
x = 3.75%2F.25
x = 15 oz of 30% alloy required
then
25-15 = 10 oz of 5% alloy:
Check solution
.30(15) + .05(10) = .20(25)
4.5 + .5 = 5
