Answer:
13. 
14. 
Step-by-step explanation:
13.
Given


Required
Determine the distance between M and S
Distance (D) is calculated using:

Where








<em>Hence, the distance between M and S is 18 units</em>
<em></em>
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.

Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is

<em>i.e. we add the units to the y coordinate of P.</em>
Answer: 20
Step-by-step explanation:
numbers belonging to the figure on the left are 2.5 times less than on the right so to find x multiply 8 by 2.5 and that is 20
Answer:
x>-2
Step-by-step explanation:
Hi there!
We are given the inequality 7+7(x+4)>21, and we want to solve it
Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.
So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).
7+7x+28>21
Now combine like terms.
7x+35>21
Subtract 35 from both sides
7x>-14
Divide both sides by 7
x>-2
Hope this helps!
