Answer:
y = 8
Step-by-step explanation:
Hello!
We can solve for y by isolating it.
<h3>Solve for y</h3>
- 3y - 15 = y + 1
- 3y - 15 - y = y +1 - y
- 2y - 15 = 1
- 2y - 15 + 15 = 1 + 15
- 2y = 16
- y = 16/2
- y = 8
The value of y is 8.
Answer:
Organisms that break down dead or decaying organisms
Step-by-step explanation:
Hope this helps :b
I am setting the week hourly rate to x, and the weekend to y. Here is how the equation is set up:
13x + 14y = $250.90
15x + 8y = $204.70
This is a system of equations, and we can solve it by multiplying the top equation by 4, and the bottom equation by -7. Now it equals:
52x + 56y = $1003.60
-105x - 56y = -$1432.90
Now we add these two equations together to get:
-53x = -$429.30 --> 53x = $429.30 --> (divide both sides by 53) x = 8.10. This is how much she makes per hour on a week day.
Now we can plug in our answer for x to find y. I am going to use the first equation, but you could use either.
$105.30 + 14y = $250.90. Subtract $105.30 from both sides --> 14y = $145.60 divide by 14 --> y = $10.40
Now we know that she makes $8.10 per hour on the week days, and $10.40 per hour on the weekends. Subtracting 8.1 from 10.4, we figure out that she makes $2.30 more per hour on the weekends than week days.
