18+x+x=180
180-18=162
162/2=81
X=81
Triangles always have a total of 180 degrees and the angles have the same variable which means they are the same number.
Answer:
I say (2,80) because if u do 80 divided by 2, u get 40. If u do 40 / 0 u get 0 and if u do 100 divided by 3, u get 33.3. So, (2,80) would still be greater.
I have added an attachment by solving the question hope u understand it
4=-2(x-3)
divide both sides by 2
2=-(x-3)
remove parentheses
2=-x+3
move terms
2+x=3
subtract numbers
x=3-2
x=1
Answer:
If x= 4 then f(x) = 4x -5 is 11.
Step-by-step explanation:
f(x) = 4x -5
We need to find the domain value that corresponds to the output f(x) = 11
In this question, we need to solve the expression for value of x such that the answer is 11.
if x= 3
f(3) = 4(3) -5
= 12 -5
= 7
Since we want the answer 11 so we cannot take x= 3
if x = 4
f(4) = 4(4)-5
= 16 - 5
= 11
So, if x= 4 then f(x) = 4x -5 is 11.
