Let the two numbers be x and y
(x+y)-18=2x
x+y-18=2x
x+y-2x=18
-x+y=18_______(1)
(x-y) -32=2y
x-y-32=2y
x-y-2y=32
x-3y=32_______(2)
from eqn (1) y=18+x____(3)
substitute eqn (3) into eqn(2)
x-3{18+x} = 32
x-54-3x=32
-2x=32+54
-2x = 86
x= -43
sub x=-43 into eqn (3)
y=18+(-43) = 18-43 = -25
Answer:
Step-by-step explanation:
Answer:
50degrees
subtract 180with140and with 90 then add
Answer:
Look below
Step-by-step explanation:
First, you solve inside the parenthesis. 13 + 7 = 20 and 12 + 4 = 16. then you do inside these []. 20 - 16 = 4. 16 divided by 4 = 4
Hope this helped.

The <em><u>correct answer</u></em> is:
D. It has the lowest y intercept
Explanation:
All 3 lines pass through the same point. The steepness of each line can help us to determine where the y-intercept of each line would lie.
The "flatter" the line that passes through this point, the higher up the y-intercept will be. The "steeper" the line that passes through this point, the lower the y-intercept will be. This means the line with the largest slope (the steepest line) will have the lowest y-intercept.
