x+5y-10=2x solve for y
Answer:
x + 5y -10 = 2x
or, 5y = 2x - x + 10
or, 5y = x + 10
or, y = (x + 10)/5

Dominick wants to determine the maximum capacity of a cylindrical bucket that has a radius of 6 inches and a
height of 12 inches. What is the capacity of Dominick's bucket? Round your answer to the nearest tenth. Don't
forget the label.
Hey there! I'm happy to help!
To find the volume of a cylinder, you multiply the base by the height.
First, let's find the base.
The base is a circle. To find the area of a circle, you square the radius and multiply by 3.14 (pi).
6²=36
36(3.14)=113.04
We multiply this by the height.
113.04(12)=1356.48
And we round to the nearest tenth.So, the maximum capacity of Dominick's bucket is 1356.5 cubic inches. If you use the entire pi number you would get something more around 1357.2, so that could be the answer if the first is incorrect.

Leslie ran a total of 8 miles over the course of 4 track practices. How many miles would Leslie have ran after 5 track practices? Solve using unit rate.
Answer:
10 miles
Step-by-step explanation:
Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.
Answer: 10 miles after 5 track practices.
Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.
8/4 converted to a unit rate is 2/1
The unit rate is 2 miles per every 1 track practice.
We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.
2/1 x 5 = 10/5
So, Leslie would have ran 10 miles after 5 track practices.

Your air conditioner hasn’t been working properly, so you decide to set up an appointment to have it fixed. The repair company tells you that it costs $99 for a one time service fee plus $50 every hour. The technician came to your house and determined the drain was clogged. The total bill came to $549. Write an equation that represents this situation. (do not use any spaces in your equation & use the letter "x" to represent your variable)
Answer:
[tex]99 + 50x = 549[/tex]
Alternatively you can write it as;
[tex]50x - 450 = 0[/tex]
Step-by-step explanation:
One time service fee=$99
Rate of service=$50/hour
let unknown hours=x
Therefore the equation is
[tex]99 + 50x = 549[/tex]
or you can further simplify it to:
[tex]50x - 450 = 0[/tex]
And you can then solve for x to be 9 hours.

What is 5x-(3+7)=9+2(x-8)
Answer:
x= 1
Step-by-step explanation:
5x - (3+7)=9+2(x-8)
Add the numbers 3 + 7= 10
5x - 10= 9 + 2(x-8)
Expand 9 + 2(x-8): 2x - 7
5x - 10 = 2x - 7
Add 10 to both sides
5x -10 + 10 = 2x -7 + 10
Simplify 5x = 2x + 3
Subtract 2x from both sides
5x -2x = 2x + 3- 2x
Simplify
3x = 3
Divide both sides by 3
3x/3 =3/3
Simplify
x= 1
