Question #1
\frac{9}{25}=\frac{x}{120}\\\\120(9) = 25x\\\\1080 = 25x\\\\x= 43.2

For #1, the answer is 43.2

Question #2
\frac{6}{5} = \frac{2580}{x} \\\\2580(5) = 6x\\\\12900 = 6x\\\\x = 2150

For #2, the answer is 2150

Need to solve for Y by filling in the blanks<br>(y +44)°, 86, (3y)°​
lapo4ka [179]
Answer:

1.89

Solution:

We have -44x - 86 = -3

First, we move the non x terms to the RHS of the equation. To do this, we add 86 to both sides.

Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86

or, -44x = 83

Next, divide both sides by -44, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c
-44x
-44
=
83
-44

or, x = -1.89


Explaination:

This is right I guess

Yes they are, the constant variation is that for every 3 added to the x side, 1 is added to the y side. I would really appreciate the brainliest mark thanks!
