Hey there! 
4.50x + 5.50x - 7.50x
= 4.5x + 5.5x - 7.5x
= 10x - 7.5x 
COMBINE the LIKE TERMS 
= (10x - 7.5x)
= 10x - 7.5x
= 2.5x 
≈ 2.50x 
Therefore, your answer is: 2.50x
Good luck on your assignment & enjoy your day!

Answer:
A) allows the population effect on log earnings of being married to depend on gender
Step-by-step explanation:
The regression equation of a dependent variable based on two or more independent variables is of the form:

Here,
<em>Y</em> = dependent variable
 and
 and  = independent variables
 = independent variables
 = interaction term
 = interaction term
 = regression coefficients.
 = regression coefficients.
If there is a significant interaction effect present then this implies that the effect of one independent variable ( or
 or ) on the dependent variable (<em>Y</em>) differs every time with different value of the other independent variable  (
 ) on the dependent variable (<em>Y</em>) differs every time with different value of the other independent variable  ( or
 or ) .
 ) .
The provided regression equation is:
 
 = dependent variable
 = dependent variable
 and
 and  = independent variables
 = independent variables
In this case the interaction term is defined as follows:
The effect of being married on log earnings is dependent on different values of the variables  , i.e. the gender of the
, i.e. the gender of the  person.
person.
Thus, the correct option is (A).

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).
Look at the picture.
We know: The sum of the measures of angles in a triangle is equal 180°.
Therefore we have the equation:
 <em>combine like terms</em>
       <em>combine like terms</em>

 <em>subtract 5 from both sides</em>
           <em>subtract 5 from both sides</em>
 <em>divide both sides by 7</em>
              <em>divide both sides by 7</em>
