Answer:

Step-by-step explanation:

We are seen with two lines crossing each other and the angle in which a line has is 180 degrees. Also, the angles labeled 3x and x are supplementary angles, which mean they add up to 180 degrees. Using this information, we can set up an equation.

$x+3x=180$

$4x=180$

$x=45$

The mayor of renee's town chose 160 students from her school to attend a city debate. This amount is no more than 1/4 of the stu

azamat

The answer is d.
First you have to divide 160/ 1/4. So you would do 160/1 divided by 1/4. Because of keep, change and flip. (k.c.f) you would keep 160/1, change the division sign, then flip 1/4 to 4/1. Then you multiply 160/1*4/1. Then you would get 640. Hope this helped.
