Answer: 
Step-by-step explanation:


We need -9x on the left side, to move it, we must add 9x on both sides.

Done. We have Ax = 9x, By = 1y and C after the equal sign = -6
Answer:
none of the above
Step-by-step explanation:
it is actually the fact that for every positive number on the number line there is a corresponding negative integer
Two dozens and you have one shell left
Solving the inequality
we get 
Step-by-step explanation:
We need to find the value of x from the inequality 
Solving:

Subtract 8 on both sides:


Divide both sides by (-1). For doing this the sign of inequality is reversed i.e, > is changed into <

So, Solving the inequality
we get

Length of the given rectangle is 8 units.
Option - D
<u>Solution:</u>
Given that
Length of a rectangle = 
Width of a rectangle = 
Area of rectangle = 20 square units
Need to calculate length of rectangle.

Substituting given value of Area of rectangle and expressions for length and width of rectangle in formula, we get

On solving above equation for x we get

On splitting the middle term in such a way that product of split terms comes as
and summation comes as -5x, we get


As length cannot be negative hence we can ignore negative value.
So length is 8 units.
