Answer:

x= -6

Step-by-step explanation:

Step 1- Distribute

5x-40=7x-28

Step 2- Move x to one side

5x-40=7x-28

-5x -5x

Step 3- Add to both sides

-40=2x-28

+28 +28

Step 4- Divide

-12÷2=2x÷2

Conclusion is x= -6

Answer:

Step-by-step explanation:

So the whole segment TV is made up of TU plus UV. In an equation:

$TV=TU+UV$

We already know that TV is 32 and UV is 20. Substitute:

$32=TU+20$

Subtract 20 from both sides:

$TU=12$

So, the length of TU is 12.

Our answer is A.

And we're done!

As the y intercept lies on the x-axis, x=0

To find the y-intercept, put x=0 into the equation:

$3(0) - 2y = - 18 \\ 0 - 2y = - 18 \\ - 2y = - 18 \\ y = \frac{18}{2} \\ y = 9$

Therefore,the y-intercept=9.

Hope it helps!

Please assist me with this math problem

Answer: see below

<u>Step-by-step explanation:</u>

I'm not sure exactly what you are asking for but here is what the box plot tells you:

Minimum is 17 items.

Q1 (Lower Quartile) is 22 items. So, 25% of the customers bought 22 items.

Q2 (Median) is 32 items. So, 50% of the customers bought 32 items.

Q3 (Upper Quartile) is 35 items, So, 75% of the customers bought 35 items.

Maximum is 62 items.

The data is "heavier" on the right so it is skewed left.

Range is 62 - 17 = 45

IQR (Interquartile range) is Q3 - Q1 = 35 - 22 = 13
