The answer is 6x
Because x is equal to 1x so 1x+2x+3x = 6x
Hope this helps :)

<h3>What is equation?</h3>
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. Solving this equation, we get the value of the variable x as x = 7.
Here,
Let her regular pay be x and overtime pay be y.
8x+4y=160
y=x+10
8x+4(x+10)=160
8x+4x+40=160
12x=120
x=10
y=x+10
=10+10
=20

Answer:
I think the answer is b
Step-by-step explanation:
We need to convert this equation to slope-intercept form first.
We can do that by solving for y.
x - 5y = 15
<em><u>Add 5y to both sides.</u></em>
x = 5y + 15
<em><u>Subtract 15 from both sides.</u></em>
x - 15 = 5y
<em><u>Divide both sides by 5.</u></em>
y = 1/5x - 3
We now know the slope is 1/5.
The slope of the line perpendicular to the line with a slope of 1/5 is -5.
The slope of a perpendicular line is the negative reciprocal of the original slope.
Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).
The equation of the new line is y = -5x - 6.
