Step-by-step explanation:
<u>20% of juice has:</u>
- 10*0.2 = 2 cups of extract
<u>If x cups of juice added we'll have:</u>
- 2 + x*0.15 = 0.17(10 + x)
- 2 + 0.15x = 1.7 + 0.17x
- 0.17x - 0.15x = 2 - 1.7
- 0.02x = 0.3
- x = 0.3/0.02
- x = 15
Answer:
x = 12
Step-by-step explanation:
Given
2(x - 3) = 9 + 3(x - 9) ← distribute parenthesis on both sides
2x - 6 = 9 + 3x - 27, that is
2x - 6 = 3x - 18 ( subtract 3x from both sides )
- x - 6 = - 18 ( add 6 to both sides )
- x = - 12 ( multiply both sides by - 1 ), thus
x = 12
