when x =1 , y = 3

when x = 3, y =27

27-3 = 24

3-1 = 2

24/2 = 12

Answer:

1. z = -15

2. p = 7

3. h = -11

4. t = 14

5. q = 12

Step-by-step explanation:

$\frac{z}{-5}+1=4$

Add -1 both sides,

$\frac{z}{-5}+1-1=4-1\\\frac{z}{-5}=3$

Multiply both sides by -5,

$\frac{z}{-5}\times-5=3\times-5\\z=-15$

Distribute 3 in $p+2$ and then add -6p and -6 both sides.

$3(p+2)=6p-15\\3\times p+3\times2 = 6p-15\\3p+6=6p-15\\3p-6p=-15-6\\-3p=-21\\p=\frac{-21}{-3}=7$

$\frac{h-7}{2}=3(h+8)$

Multiply both sides by 2,

$\frac{h-7}{2}\times2=3(h+8)\times2\\h-7=6(h+8)\\h-7=6h+48$

Add -6h and 7 both sides,

$h-6h-7+7=6h-6h+48+7\\-5h=55\\h=\frac{55}{-5}\\h=-11$

$4t+2-5=3(t+7)-9\\4t-3=3t+21-9\\4t-3=3t+12$

Add -3t and 3 both sides.

$4t-3t-3+3=3t-3t+12+3\\t=15$

$2(q-4)=4(q-8)\\2q-8=4q-32$

Add -2q and 8 both sides.

$2q-8-4q+8=4q-4q-32+8\\-2q=-24\\q=\frac{-24}{-2}\\q=12$

Therefore,

1. z = -15

2. p = 7

3. h = -11

4. t = 14

5. q = 12

If your total annual income was $30,694.95, then how much did you earn per month, on average?

tatuchka [14]

In average, your monthly income is $2,557.91

<h3>How much did you earn per month, on average?</h3>

We know that in the year you win a total of $30,694.95, and we want to know how much you win per month.

We know that in a year there are 12 months. To get how much you win, in average, in one of these months, you need to take the quotient between the total amount that you earn in one year, and the number of months in a year.

It gives:

N = $30,694.95/12 = $2,557.91

In average, your monthly income is $2,557.91

Answer:

A and E

Step-by-step explanation:

um for some reason my answer was deleted…

anyways, I think its A and E because the equation should be g = 2/5t and 0.4 is equal to 2/5 so that means that E is also correct.
