Find x if the average of 19, 12, 14, 18, and x is 12.

-3

Step-by-step explanation:

To do this, let's arrange it into an equation:

(19+12+14+18+x) / 5 = 12

Let's shift the 5 to the other side by multiplying 12 by 5, which is 60. Now the equation looks like this:

19+12+14+18 + x = 60

Now let's add 19, 12, 14 and 18 together, which is 63:

63 + x =60

Let's move the 63 over to the other side by subtracting it from 60, so 60-63 equals -3. Hence, the answer is -3. Hope this helps!

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
