Answer: 10 hours
Explanation:
1) Fernando's earnings:
10 + 4h ← 10 is a fix charge, h is the number of hours and 4 is the rate per hour
2) Fernando's savings
0.30 (10 + 4h) ← 30% = 30 / 100 = 0.3
3 + 1.2h ← distributive property
3) Brenna's earnings
6h ← h is the number of hours, 6 is the rate per hour
4) Brenna's savings
0.25(6h) ← 25% = 25/100 = 0.25
1.5h ←0.25 × 6 = 1.5
5) Equal savings
3 + 1.2h = 1.5h
1.5th- 1.2h = 3 ← transpose terms
0.3h = 3 ← combine like terms
h = 3 / 0.3 = 10 ← divide by 0.3
Answer: h = 10
Answer:
Lindsey owns 12 books
Step-by-step explanation:
1/3x:Lindsay
x:Destiny
1/4x: Henry
1/3x+1/4x+x=57
4/12x+3/12x+x=57
7/12x+x=57
19/12x=57
x=57*12/19
x=36
1/3x=36/3
1/3x=12

Take out a common factor between 3x and kx. That means use the distributive law to get what you normally would start with.
x(k + 3) = 4
Now divide by k + 3
x = 4/(k + 3)
That's as much as you can do with this question.
