Answer:
scalene triangle
Step-by-step explanation:
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
Answer:
X = 0.8
Step-by-step explanation:
reorder the terms by moving all terms that contain X to the left, and all the others to the right.
add 2X to both sides
Combine like terms
add (-5) to both sides
combine like terms
divide both sides by 5
