Answer: X=31
Step-by-step explanation:
The angles are supplementary because they add up to 180 degrees. Therefore, we will make the angles equal 180 degrees using
3x+25+2x = 180
combine like terms
5x+25=180
subtract the 25 from both sides
5x=155
divide each side by 5
answer x=31
Answer:
the answer would be c.
Step-by-step explanation:
We have that an inverse variation in a function is given by:

We must find the value of the constant k.
To do this, we substitute the values of x1 = 12, y1 = 15.
We have then:

Clearing k we have:

Substituting the value of k we have that the inverse variation is:

For y2 = 3 we have:

Clearing x2 we have:
