Answer: 63 degrees.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Therefore: 54 + y + y = 180
So 54 + 2y = 180
So 2y = 126
Therefore y = 63 degrees.
Hello!
We are given the equation below.
x+40=3x
We want to get all of the variables on side. First of all let's subtract 40 from both sides.
x=3x-40
Now we rearrange our equation so the commutative property will work.
x=3x+(-40)
x=-40+3x
Now we subtract 3x from both sides.
-2x=-40
We divide both sides by -2.
x=20
Our answer is A) 20.
I hope this helps!
Answer: isolate the variable by dividing each side by factors that don't contain the variable.
x is less than or equal to 15
