Answer:
Step-by-step explanation:
a) set up the variables
Let x represent the first number Then y will represent the second number.
b) What is the equation that represents the above situation?
c) Solve the equation.
<u>Substitute x in the second equation and solve for y:</u>
- x + y = 51
- 2y + y = 51
- 3y = 51
- y = 51/3
- y = 17
<u>Then find x</u>

Given:

To find:
The steps to solving the given inequality.
Solution:
We have,

Subtract 8 from both sides.


Divide both sides by 3.


Two steps are:
1. Subtract 8 from both sides of the inequality.
2. Divide both sides of the inequality by 3.
Therefore, the correct option is A.
Firstly, we need to draw triangle
we know that
O is a centroid
and centroid divides median into 2:1
so,

we have FO=4
so, we can plug it


now, we can find CF
CF=OC+FO
CF=8+4
CF=12
now, we can see triangle ACF is a right angled triangle
so, we can use pythagoras theorem

now, we can solve for x



Since, it is equilateral triangle
so,

we know that
E is a mid-point
so,

now, we can plug values

Sandra did not get enough points.
They needed 15, but got 22 and a -8 as well.
So 22-8 = 14
14<15
