Answer:
10
Step-by-step explanation:
Since we know that B is between A and C, it doesn't matter where B is, but, we are sure that AB plus BC equals AC. In an equation:
We know that AB is 22, BC is 16x, and AC is 182. Substitute:
Now, find the value of x. Subtract 22 from both sides:
Divide both sides by 16:
So, the value of x is 10.
And we're done!

Answer:
Option C is correct.
Solution to the given system of equation is (6 , -8)
Step-by-step explanation:
Given the system of equation:
......[1]
.....[2]
Substitute the equation [1] in [2] we get;
Combine like terms;
Add 10 to both side of an equation:
Simplify:
Divide both sides by we get;
Simplify:
x = 6
Substitute the value of x =6 in equation [1] we get;
or
Simplify:
y = - 8
therefore, the solution to the given system of equation is; (6 , -8)
