Hi there!

8x + 4y = 15
x + y = 3
Use the second equation to solve for a particular variable since it is easier to isolate. We can begin by solving for y:
x + y = 3
Subtract y from both sides:
x = -y + 3
Substitute in this expression for x into the other equation:
8(-y + 3) + 4y = 15
Distribute and simplify:
-8y + 24 + 4y = 15
-4y + 24 = 15
-4y = -9
y = 9/4
Substitute in this value of y to solve for x:
8x + 4(9/4) = 15
8x + 9 = 15
8x = 6
x = 6/8 = 3/4
The values respectively are:
x = 3/4, y = 9/4
The monthly deduction is $250.80
Given:
monthly pay = 1,254
monthly rate of deduction = 20%
Simply multiply the rate to the monthly pay to get the value of the deduction.
1,254 * 20% = 250.80 deduction 1,254 - 250.80 = 1,003.20 take home
Answer:
Step-by-step explanation:
11- C
12-b
Given :
∠m1 = ( 7x - 19 )° .
∠m2 = ( x + 5 )° .
To Find :
The value of x .
Solution :
Since , relation between angle ∠m1 and ∠m2 is not given .
Let , us assume that sum of ∠m1 and ∠m2 is 180° .
So ,

Angle ∠m2 = (24.25 + 5 )° = 29.25° .
Therefore , ∠m2 = 29.25° .
Hence , this is the required solution .
