3x+2(x-1)=9x=4
We move all terms to the left:
3x+2(x-1)-(9x)=0
We add all the numbers together, and all the variables
-6x+2(x-1)=0
We multiply parentheses
-6x+2x-2=0
We add all the numbers together, and all the variables
-4x-2=0
We move all terms containing x to the left, all other terms to the right
-4x=2
x=2/-4
x=-1/2
X would equal 53° since a triangle has to equal 180°, 65 + 62 = 127, 180-127=53°
Answer:the first ans (f(x)=(1/x+2)+3
Step-by-step explanation:
Answer: 13 100 dollar bills.
Step-by-step explanation: you would just do 100*13 which gives you 1300
Answer:
x=17
Step-by-step explanation:
This should be for a "kite": AD=DC, AB=BC and ∠A=∠C
8x-27 = 3x+58
5x = 85
x = 17
