Answer:

38 is your answer :)

Step-by-step explanation:

So what you want to do is P.E.M.D.A.S (parenthesis, exponets, multiplication/division, addition/subtraction) * whatever comes first always do it in order*

3^2+12/ (6-3) x 8

6-3 = 3

3^2+12/(3)*8

3^2+4*8

6+4*8 =32 and 32+6 = 38

To solve this, remember the acronym PEMDAS

parenthesis, exponents, multiplication, division, addition, subtraction

start by doing (6-3), which is 3

now the equation is 3^2+12 / 3 x 8

then do 3^2, which is 9

9+12 / 3 x 8

now do 3 x 8, which is 24

9+12 / 24

divide 12 and 24, which is one half

9 + 1/2

add this to get 9.5

hope this helped!!

Solve each system by substitution.<br> 1) y = 2x + 2<br> y = -5x + 16
dalvyx [7]

Answer:

y = 6

x = 2

Step-by-step explanation:

rearrange the first equation in terms of x

x = (y - 2)/2

substiute x in the second equation

y = -5[(y-2)/2] +16

Now simpilify and solve for y

y = (-5y + 10)/2 +16

y = -5/2y + 5 + 16

y + 5/2y = 5 + 16

3.5y = 21

y = 6

Now substitue y in the first equation to solve for x

x = (6 - 2)/2

x = 2
