Answer:

second number= X

first number = X+8

third number X/3

sum of three numbers is 50.

X+X+8+X/3=50

2x+x/3=50-8

(6x+x) / 3 =42

7x =42*3

X =42*3/7

=18

Second number=18

third number= 18/3=6

first number=18+8=26

What is the slope of this line​
Rashid [163]

Answer:

Slope = 2/3

Step-by-step explanation:

Slope = Change over y (rise) over change over x (run)

Pick two dot points on the line

Count how many units over they are until you get to the next dot, then count how many units up until you reach the next dot

Remember: Y runs vertically, X runs horizontally

Put the unit number that ran vertically on the top, then put the unit number that runs horizontally on the bottom

If needed simplify

The slope is 2/3
