Answer:
d
Step-by-step explanation:
9 boys to 22 girls
9:22
Let the number = X
You would multiply x by the percent to equal 72:
X * 0.18 = 72
Divide both sides by 0.18
72 / 0.18 = 400
The answer is A)400
Answer:
Answer would be x=1.
Step-by-step explanation:
Answer:
( x - 2 ) & ( 3 x - 2 ) = 0 are the factors of the given equation.
Step-by-step explanation:
The given equation is 6 x² + 8 x - 8 = 0 ......................(i)
<em>Divide by 2 in equation (i) both sides-</em>
<em>3 x² + 4 x - 4 = 0</em>
<em>3 x² + 6 x - 2 x - 4 = 0</em>
<em>3 x ( x + 2 ) - 2 ( x + 2 ) = 0</em>
<em>( x - 2 ) (3 x - 2 ) = 0</em>
Hence ( x - 2 ) & ( 3 x - 2 ) = 0 are the factors of the given equation.
