Answer: 55x + 75 = 350; 5 hours
Step-by-step explanation:
What we know:
- A flat fee is $75
- John charges $55 an hour
- The total charge is $350
We need to write an equation to find how many hours John works.
<em>x </em>will represent hours worked.
55x + 75 = 350
We now need to solve for x.
Subtract 75 from both sides.
55x + 75 - 75 = 350 - 75
Simplify.
55x = 275
Divide 55 from both sides.
55x/55 = 275/55
Simplify.
x = 5
John worked 5 hours.
To check our work, we just plug in our x value!
55(5) + 75
275 + 75 = 350

Answer:
x = -7
Step-by-step explanation:
8x - 9 = 12 + 11x
Subtract 11x to both sides of the equation. Then, it will look like this:
-3x - 9 = 12
Add 9 to both sides of the equation. After that, it will look like this:
-3x = 21
Divide both sides of the eqution by -3. Your answer is:
x = -7
Answer:
d > -3
Step-by-step explanation:
