You know that we have to simplify the algebra equation, so first you have to combine x and 2x. X + 2x equals to 3x. Now that we combined x and 2x which makes 3x, we have to do 7 and -8. 7 + -8 which equals to -1. Therefore, the answer to this algebra equation is 3x + -1.
That would be 180 - 72 = 108 degrees
Subtract 4 from both sides, y = 5
Answer:
k = 7
Step-by-step explanation:
9.1k = 63.7
/9.1 /9.1
k = 7
Check your answer:
9.1k = 63.7
9.1 (7) = 63.7
63.7 = 63.7
This statement is true.
Hope this helps!
