Answer:
a)8cm
b)30inches
Step-by-step explanation:
Answer:
the linear equation is y=2 so anything that lands on that line after it is graphed, so the option (3,2)
Step-by-step explanation:
Given:
The system of equations:


To find:
The sum of the x- and y-values in the solution to the system of equations.
Solution:
We have,
...(i)
...(ii)
From (i) and (ii), we get



Multiply both sides by 3.

Divide both sides by 16.


Putting x=4 in (i), we get

The solution of system of equations is (4,12).


Therefore, the sum of the x- and y-values in the solution to the system of equations is 16.
If you would like to solve the equation <span>? + (? + ?) = 13, you can do this using the following steps:
</span><span>? + (? + ?) = 13
</span><span>? + ? + ? = 13
</span>3 * ? = 13
? = 13/3
? = 4 1/3
The correct result would be <span>? = 4 1/3.</span>
