Answer:
2nd number = 13
First number = 15
3rd number = 30
Step-by-step explanation:
Let
2nd number = 1/2x - 2
First number = 1/2x
3rd number = x
Total = 58
x + 1/2x + 1/2x - 2 = 58
x + x+x/2 = 58 + 2
x + 2/2x = 60
x + x = 60
2x = 60
x = 60/2
= 30
x = 30
2nd number = 1/2x - 2
= 1/2*30 - 2
= 15 - 2
= 13
First number = 1/2x
= 1/2*30
= 15
3rd number = x
= 30
Yes because if you plug in (-1,2) to each equation you get a true statement.
Answer: Keep the equal signs lined up, Even if you can do it your head, write it all out. If less than 4 inches of room, get out a new sheet of paper to do it on.

Answer:
900
Step-by-step explanation:
30 x 5 = 150 and 150 x 6 = 900. You would make a model with 5 rows of 30, then make 6 of them
Answer:
The slope of the line is 
Step-by-step explanation:
Slope:
When we have two points on a line, the slope is given by the change in y divided by the change in x.
Two points on a line are M(4,5) and N(-2,9).
Change in y: 9 - 5 = 4
Change in x: -2 - 4 = -6
The slope is:
The slope of the line is
