Answer:
9:6
Step-by-step explanation:
boys= 9 teammates
girls= 6 teammates
x^2 + 2x x^2 - 4
------------------- - --------------------
x^2 - 2x - 8 x^2 - 2x - 8
x(x + 2) - (x+2)(x-2)
= --------------------------------------
(x + 2)(x - 4)
(x + 2) ( x - x + 2)
= --------------------------------------
(x + 2)(x - 4)
2
= ------------
(x - 4)
x is NOT equal -2 and 4
Answer:
Pyramid
Step-by-step explanation:
For this case what you should do is the following system of equations:
x: skilled laborers
y: unskilled laborers
By writing the system we have:
x + y = 24
25x + 12y = 405
Solving the system:
Step 1:
-25x + -25y = -600
25x + 12y = 405
Step 2:
-13y = -195
y = 195/13
y = 15
step 3:
x = 24-y
x = 24-15
x = 9
Answer:
skilled laborers = 9
unskilled laborers = 15
Steps:
"Of" means "x" (times)
For 20% pretend there is an imaginary decimal at the end and move that decimal all the way to the front.
Now what is .20 of (times) $60 = 12
I think that's what you wanted. The discount price
