Answer: 12

40% = 40/100 = 0.40

"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12

Optionally, you can solve the equation below for x

part/whole = percent/100

x/30 = 40/100

x/30 = 0.40

x = 0.40*30

x = 12

much of those steps follow a similar pattern to what was mentioned earlier.

y=-x

slope for perp line = 1

2y=-x+6

y=-1/2x +3

slope for perp line = 2

15.

i don’t wanna do all sorry it’s a lot of work so i’ll tell u how to do it instead. first write it in slope intercept form which is

y-y1=m(x-x1)

it’s parallel which means it shares the same slope. if it’s perpendicular it would be opposite reciprocals so for -3/2 the perp slope would be 2/3.

the line is

y+1=3/4(x-4)

we distribute the 3/4 so it’s now

y+1=3/4x-3

then we subtract the 1

y=3/4x-4 is the equation boom done

Plz help!!!! Number 23
Minchanka [31]

Answer:

 (0 + m)/2, (0 + n)/2.

Step-by-step explanation:

The  x coordinate of the  midpoint must be halfway  between the x coordinates of  A and B, and the y coordinate must be  found in the same way.

So the midpoint is  (0 + m)/2, (0 + n)/2.
