Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50

Answer:
Step-by-step explanation:
<u>The scale is </u>
- 15 in ÷ 24 feet =
- 15 in ÷ 24*12 in =
- 15 in ÷ 288 in =
- 5 in ÷ 96 in =
- 5 ÷ 96
Answer:
Pull out like factors
2x + 24 = 2 • (x + 12)
2x + 24 = 2x + 24
This equation is a tautology or an Identity meaning it's always true.
