What is x+8=(-5) and how do expan it

X= -13

Step-by-step explanation:

The goal is to get x by itself!

Rule of thumb: whatever you do to the left, you MUST do to the right

Step 1: Subtract 8 from the left side of the equation (the  =  sign)

x + 8 = (-5)

  - 8 --> this gets x by itself

Step 2: Subtract 8 from (-5) on the right side (because you did it on the left

x = (-5)

     - 8

*note: x is now by itself*

Step 3: Solve!

x = (-5) - 8 -13

x = -13

the answer is

d.

5.3066 m2

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
