Answer:
x=2
Step-by-step explanation:
i'm not sure how to do the modeling and the grouping part but here's the solve and check portion. I hope i helped a little!
solve;
3x=6 divide each side by 3 to isolate x
x=2
check;
plug 2 into x and see if the statement is true.
3(2)=6
6=6 true? yes.
Gosh, when I saw that my mind went blank
Multiply your equation by the inverse of the coefficient of d to get d by itself.

With d on the left, this is
... d = r·t
Hey there! :)
Answer:
y + 32 = 3(x + 8)
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:

Plug in the coordinates of the points into the equation:

Simplify:

m = 3.
Point-slope form is:
y-y₁=m(x-x₁)
Plug in the coordinates of the first point, as well as the slope:
y - (-32) = 3(x - (-8)
y + 32 = 3(x + 8)
Answer: 1. x can vary by numbers over 13, the third one is 6x-5=18. x is the answer when you solve for it
Step-by-step explanation: 1. x>12-5
3. 6x-5=18
