You need to use "tex" "/tex" with square brackets around the "tex" and "/tex" to wrap latex here...
![\sqrt[3]{125}=5 \ because \ 5^3=125](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125%7D%3D5%20%5C%20because%20%5C%205%5E3%3D125%20)
Answer: the hourly cost of renting a power washer is $5
the hourly cost of renting a generator is $10
Step-by-step explanation:
Let x represent the hourly cost of renting a power washer.
Let y represent the hourly cost of renting a generator.
On his first job, he used each piece of equipment for 6 hours which cost $90. This means that
6x + 6y = 90 - - - - - - - - 1
On his second job, he used the power washer for 4 hours and the generator for 8 which cost $100. This means that
4x + 8y = 100 - - - - - - - - - - 2
Multiplying equation 1 by 4 and equation 2 by 6, it becomes
24x + 24y = 360
24x + 48y = 600
Subtracting, it becomes
- 24y = - 240
y = - 240/-24 = 10
Substituting y = 10 into equation 1, it becomes
6x + 6 × 10 = 90
6x + 60 = 90
6x = 90 - 60 = 30
x = 30/6 = 5
Ok if I remember my math lessons the algebraic expression would be
X divided by 8

thank u so I was like wait for the next day to get back in my head is the way it is now I have a 5
