Answer:
7.56 hours.
Explanation:
So my equation will be:
$45 + $24h
If we need to find out how many hours you have to work in order to earn $117 working at two separate work sites, the equation would look like this:
45 + 25h รท 2 = 117.
First we need to multiply both sides of th equation by 2.
![(2\left(45+25h\right))/(2)=117\cdot \:2](https://img.qammunity.org/2021/formulas/mathematics/high-school/emttjk2s4cs7j69iifgt9d5nya027w6pv5.png)
Then, I had to simplify.
![5+25h=234](https://img.qammunity.org/2021/formulas/mathematics/high-school/95nz2kjeb05fa8qw92citgh1d4pufzvjt9.png)
After simplifying, it was about time to subtract 45 from both sides of the equation.
![45+25h-45=234-45](https://img.qammunity.org/2021/formulas/mathematics/high-school/gpnw4axofjcc4rvp43pnyb0nj0xnleo8q5.png)
I had to simplify again, then divide both sides by 25.
![25h=189](https://img.qammunity.org/2021/formulas/mathematics/high-school/8f9dkxfcw5cgt7omai74taxxyerh68jlvk.png)
![(25h)/(25)=(189)/(25)](https://img.qammunity.org/2021/formulas/mathematics/high-school/kno6z4n8ulmwmqs85yi6w587trgfdfinxu.png)
Again, I have to simplify for a final time to get the answer of..
![h=(189)/(25)](https://img.qammunity.org/2021/formulas/mathematics/high-school/9zwjmgj1sctz9mv9cygijeugw84urr6cqq.png)
In decimal form, thats equal to 7.56 hours.
h = 7.56.
