Answer:
=6
Step-by-step explanation:
find the LCM of the two denominators 3 and 6 which is 6
equate in that such that 6÷3*2x=4x
6÷6×x=x
add the two=5x
5x/6=5
multiply by six both sides
5x=30
divide both sides by 5 to get x
x=6

Answer:
108 gadgets
Step-by-step explanation:
We can use a ratio to solve
24 gadgets x gadget
------------------- = ---------------
2.5 hours 11.25 hours
Using cross products
24 * 11.25 = 2.5 *x
270 = 2.5x
Divide by 2.5
270/2.5 = 2.5x/2.5
108 = x
Hey there!
To use the substitution method in order to solve the system of equations,
y=7x+8
y=x+20 , first notice that both equations are set equal to the same value, y.
Knowing this, 7x+8 and x+20 both equal the same value so you would set them equal to one another:
7x+8=x+20.
This would be substitution as you are substituting one of the equations in place of y.
Now, solve for x:
7x+8=x+20
6x+8=20
6x=12
x=2
Now that you know x equals the value of 2, you can substitute the value into one of the equations to find y:
y=x+20
y=2+20
y=22
Now that you have x=2 and y=22, you can conclude that your answer would be (2,22) or choice B.
Hope this helps and have a wonderful day! :)

Answer:
The surface area of the cylinder is 
Step-by-step explanation:
we know that
The surface area of the cylinder is equal to
![SA=2[\pi r^{2} ]+2\pi rh](https://tex.z-dn.net/?f=SA%3D2%5B%5Cpi%20r%5E%7B2%7D%20%5D%2B2%5Cpi%20rh)
In this problem we have
----> see the attached figure
assume
substitute
![SA=2[(3.14)(5)^{2} ]+2(3.14)(5)(12)](https://tex.z-dn.net/?f=SA%3D2%5B%283.14%29%285%29%5E%7B2%7D%20%5D%2B2%283.14%29%285%29%2812%29)
