Assuming this is the equation you want to operate on:



Before final operation we have to assume that x is not equal to 0. :)
Answer:
I think this is a true or false if so the answer is true:)
Answer:
Corresponding Angles Theorem
x = -5
Step-by-step explanation:
Since they are corresponding angles, they are equal to each other.
x + 105 = 100
x = -5
Answer:
-0.4 = −2/5
Step-by-step explanation:
Rewrite the decimal number as a fraction.
-0.4/1
Multiply to remove 1 decimal places.
-0.4/1 x 10/10 =4/10
Find the GCF.
4 ÷ 2/10 ÷ 2 = 2/5
x = 2/5
-2/5
