So, X=8 right?
4x+8
Now, if we replace x with 8, we get 4(8) + 8. Now, the first think you do is multiply. So, 4(8) = 32. We now have 32+8, since we fixed the left part. Now, all you have to do is add 32+8, and you get 40.
Hope this helps!

Answer:

Step-by-step explanation:

An expression dose NOT have an = sign

An equation dose have an = sign

In this case, the expression 4x+8, replace the x with 3, since x=3

4x + 8

4 x 3 + 8 ( don't forget PEMDAS )

12 + 8

1. In the figure, m DE = 106 degrees and m BC = 62 degrees. The diagram is not to scale.

k0ka [10]

For question 1, the formula for that is m1= 1/2(a-b). 106 being A and 62 being B. You should get m1=.5*(106-62) which equals B.22

You work in a chemical lab. Last quarter, you successfully completed an average of about 5 chemical analyses per day. This quart

Kryger [21]

Answer: 60%

Step-by-step explanation:

Since, According to the question, Last quarter, we successfully completed an average of about 5 chemical analyses per day.

Therefore initially our average = 5 chemical analyses per day.

Again, From the question, This quarter, we have increased this average to about 8 per day.

Therefore New average =chemical analyses 8 per day

Thus, Percentage change in the average = (Initial average - New average)×100/ initial average

= $\frac{8-5}{5} \times 100$
