Answer:
x=30h
Step-by-step explanation:
First, you need to figure out how much she actually paid for lessons, so you need to subtract 45 from 165.
165-45=120
Now you know she paid 120 dollars in total for lessons.
You know she took four hours of lessons, so you divide 120 by 4.
120/4=30
It takes $30 an hour for lessons.
Now you can form an equation.
Since you know it takes $30 per hour of lessons, it will be 30h.
x is the full amount of money paid
You don't need to add 165-45 to your equation because not everyone will need to rent skis when they come to White Peaks.
Hope this helps!
Answer:
its 12
Step-by-step explanation:
because if you x it buy 6 and divide by 9 thats 12 and to make sure its right you just do the process in reverse
We know that the three angles of a triangle always add up to 180.
Therefore, we have the equation:
55+20+x=180.
Solving for x, we get x=105.
