Answer:
First number: 20
Second number: 30
Step-by-step explanation:
First#: x
Second#: y
Constraints:
x + y = 50
1/4x + 2/3y = 25
Isolate variable y:
x + y = 50
-1/4 (x + y = 50 )
-1/4x - 1/4y = -12.5
Add equations the two equations to eliminate x:
-1/4x - 1/4y = -12.5
1/4x + 2/3y = 25
_________________
5/12y = 12.5
5y = 150
y = 30
Substitution to find x:
x + y = 50
x + 30 = 50
x = 20

Answer:
-3/2
Step-by-step explanation:
Let P = the combined perimeter for the rectangle and square.
P = rectangle + triangle
P = 2(2x) + 2(x - 3) + x + x - 2 + x + 4
P = 4x + 2x - 6 + 3x - 2 + 4
P = 9x - 8 + 4
P = 9x - 4
