5x-70+ 4x+12= 180
9x-58=180
9x= 180+58
9x= 238
X=26.4

Wouldn’t you add both of the equations together and set them equal to 180 and whatever you get for x just plug back in to find the values of the angles??

lesantik [10]

Categorical variables can assume values from a range of possible options, whereas quantitative variables can assume possibly infinitely many values from a certain number range.

So, the answer is "the colour of the bookshelf", because there can only be a limited number of possible colours for the bookshelf, whereas its width (no matter the unit measure) and height could be any number.

What are the coordinates of point B?

zaharov [31]

Point a is at (-2,4) => (x1,y1)

Midpoint is (2.5, 3.5) => (a,b)

Point B is (x2, y2)

To find midpoint we use formula

$(a=\frac{x_1+x_2}{2} , b= \frac{y_1+y_2}{2})$

a= 2.5, b= 3.5, x1= -2 and y1= 4

Plug in all the values and findout x2, y2

$(2.5=\frac{-2+x_2}{2} , 3.5= \frac{4+y_2}{2})$

multiply 2 on both sides to remove fraction

(5 = -2+x2 , 7 = 4+ y2)

5 = -2+x2, so x2= 7

7 = 4+ y2, so y2= 3

The point B is ( 7, 3)
