Answer:
6. The number is 
7. The two numbers are
and 
Step-by-step explanation:
Question six can be re-worded to create the following expression:

Solve for x to find the number:

Question seven can be solved by first listing the constraints (assuming x is smaller than y):
- x and y are less than 20


To get the numbers, we can create a system of linear equations. First, solve for
in each expression:


Solve for
:

Solve for
:

[tex}r - 5 \frac{5}6 + 5\frac{5}6 = 10 +5\frac{5}6{/tex]
The answer is: "12 feet" .

Note: In a square, the length of EACH of the four sides of the square is the same.
Area = Length * width.
For a square, length = width.
So for a square, Area = length * width = (length of a side)² = s² ,
Given: A = s² = 144 ft² ;
Solve for the positive value of "s" .
________________________________
→ s² = 144 ft² ; Take the "square root" of each side ;
→ √(s²) = √(144 ft²) ;
→ s = 12 ft.
_______________________________
The answer is: 12 ft.

A linear pair is a pair of angles that form a line. When added, they will equal 180.
< EFG + < GFH = 180
5n + 20 + 3n + 16 = 180
8n + 36 = 180
8n = 180 - 36
8n = 144
n = 144/8
n = 18
< EFG = 5n + 20.....5(18) + 20 = 110 <==
< GFH = 3n + 16.....3(18) + 16 = 70 <==
Answer: 48/10
Step-by-step explanation: 65/10 - 17/10 = 48/10 also known as 4 8/10
