Answer: 15
Step-by-step explanation:
Ratio means only one thing but I think what you meant was 3 examples of a ratio. In that case three examples would be:
2:3,
2 to 3,
2/3
Answer:
( 10,20 )
Step-by-step explanation:
Y=2x
Y= 3x -10
What is the solution to the system of equations?
2x=3x-10 *combine like terms*
-1x= -10 x=10 *divide*
Y=2(10) y=20 *plug in for y into other equation*
CHECK:
plug both x and y into both equations to get a true statement.
Y=2x 20=2(10) 20=20
Y= 3x -10 20= 3(10) -10 20=20
following expression

<u>Step-by-step explanation:</u>
Here we have , following expression to evaluate . 1/3(9 - 18x) + 1/4(8x - 12 or ,
:
⇒ ![\frac{1}{3}(9 - 18x) + \frac{1}{4}(8x - 12)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%289%20-%2018x%29%20%2B%20%5Cfrac%7B1%7D%7B4%7D%288x%20-%2012%29)
⇒ ![\frac{1(4)}{3(4)}(9 - 18x) + \frac{1(3)}{4(3)}(8x - 12)](https://tex.z-dn.net/?f=%5Cfrac%7B1%284%29%7D%7B3%284%29%7D%289%20-%2018x%29%20%2B%20%5Cfrac%7B1%283%29%7D%7B4%283%29%7D%288x%20-%2012%29)
⇒
{ Making denominator of both terms same ! }
⇒ ![\frac{(9 - 18x)(4)+(8x - 12)(3)}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B%289%20-%2018x%29%284%29%2B%288x%20-%2012%29%283%29%7D%7B12%7D)
⇒ ![\frac{9(4) - 18(4)x+8(3)x - 12(3)}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B9%284%29%20-%2018%284%29x%2B8%283%29x%20-%2012%283%29%7D%7B12%7D)
⇒ ![\frac{36- 72x+24x - 36}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B36-%2072x%2B24x%20-%2036%7D%7B12%7D)
⇒
{ Simplifying even further }
⇒ ![-4x](https://tex.z-dn.net/?f=-4x)
Therefore , following expression
is equal to
