X - y + x + y = 180
2x = 180
x = 90
2x - 2y = x + y
x = 3y
y = x/3
y = 90/3
y = 30
x - y = 90 - 30 = 60
x + y = 90 + 30 = 120
2x - 2y = 180 - 60 = 120
Answer:
(f-g)(x) = x-3
Step-by-step explanation:
f(x)=3x-2
g(x)=2x+1
(f-g)(x)= 3x-2 - ( 2x+1)
Distribute the minus sign
3x -2 -2x -1
Combine like terms
x-3
There was 16 bagels, and now there is 0 bagels. So what you do is subtract 16 from 16 to get 0.
X= 12.5, this is because you need to add 25 to the other side of the equation to make 2x = 25 and then divide both sides by 2 to get x=12.5
The sum of Supplementary angle =180 degrees
(2x+3)⁰ +(3x+2)⁰=180⁰
adding like terms
5x+5=180
5x=180-5
5x=175
x=175/5 =35 degrees
so the two angles are :
(2x+3)⁰ =2*35 +3 = 73⁰
(3x+2)⁰=3*35 +2 =105+2 = 107⁰
so correct option is D , 73⁰ and 107⁰
