Answer:
well I didn't understand the question
Step-by-step explanation:
please put me in brainlist
2 + 4(3+2x) = 3x + 8
2 + 12 + 8x = 3x + 8
14 - 8 = 3x - 8x
6 = -5x
x = -6/5
Answer:
D. 7
Step-by-step explanation:
to find the median the equation is to write out all the numbers given in order from least to greatest.
4, 4, 6, 6, 7, 7, 9, 9, 10
now cross off 1 number from each side. and keep doing thaf until you find the median, aka the middle number.
4, 6, 6, 7, 7, 9, 9
cross off the first and last number that remains.
6, 6, 7, 7, 9
again until 1 number remains **that number left will be the median**
6, 7, 7
cross off first and last.
7
7 will be the median.
I hope this helps!! if you need more explanation let me know and I will supply more information.
thank you

![\rm \dfrac12=\dfrac{a+b}{a-b}](https://tex.z-dn.net/?f=%5Crm%20%5Cdfrac12%3D%5Cdfrac%7Ba%2Bb%7D%7Ba-b%7D)
Let's multiply both sides by 2,
![\rm 1=2\dfrac{a+b}{a-b}](https://tex.z-dn.net/?f=%5Crm%201%3D2%5Cdfrac%7Ba%2Bb%7D%7Ba-b%7D)
and then multiply both sides by (a-b),
![\rm a-b=2(a+b)](https://tex.z-dn.net/?f=%5Crm%20a-b%3D2%28a%2Bb%29)
distribute the 2,
![\rm a-b=2a+2b](https://tex.z-dn.net/?f=%5Crm%20a-b%3D2a%2B2b)
add b to each side,
and subtract 2a from both sides,
![\rm a-2a=b+2b](https://tex.z-dn.net/?f=%5Crm%20a-2a%3Db%2B2b)
![\rm -a=3b](https://tex.z-dn.net/?f=%5Crm%20-a%3D3b)
![\rm a=-3b](https://tex.z-dn.net/?f=%5Crm%20a%3D-3b)
divide by b to find the ratio,
![\rm \dfrac{a}{b}=-3](https://tex.z-dn.net/?f=%5Crm%20%5Cdfrac%7Ba%7D%7Bb%7D%3D-3)
Hope that helps! :)
Answer: The answer is -4
Step-by-step explanation:−40=12x+8
Step 1: Flip the equation.
12x+8=−40
Step 2: Subtract 8 from both sides.
12x+8−8=−40−8
12x=−48
Step 3: Divide both sides by 12.
12x
12
=
−48
12
x=−4
Answer:
x=−4
