Answer:
Step-by-step explanation:
3 rows of 21 sneakers.
If you add 21+21 it equals 42, which is two rows. If you add that last row, 42+21, you end up with 63.
First, you must use ADDITION to find -12 + 8 (-4)
Then, use MULTIPLICATION to find -4*2 (16
1) Addition
2) Multiplication
The blank space is found by dividing 36a^2 by 12, which is equal to 3a^2
To get to this answer you need to
1. divide the both sides of the equation by 12.
2. subtract 2b^2 from both sides.
You will see that the blank space equals 3a<span>^2 then</span>
The slope-intercept form of a line:

m - slope
b - y-intercept
Convert 2x + 3y = -6 to the slope-intercet form:
<em>subtract 2x from both sides</em>
<em>divide both sides by 3</em>

Let
and 

We have 
Therefore

We have the equation of a line:

Put the coordinates of the point (0, 0) to the equation:


Answer: 
Marks of Bobbie = x
Then, marks of Georgia
= 3 times marks of Bobbie
= 3 times m
= 3 × m
= 3m
