Answer:
4/-3
Step-by-step explanation:
To find the slope
y2 - y1 / x2 - x1 =
12 - -4 16
---------- = ----
1 - 13 -12
Simplify by dividing both parts by 4
4/-3 is your slope :)
Answer:
230 cm squared
Step-by-step explanation:
Split the shape into a triangle and a rectangle
The area of a triangle is base x height / 2
20 x 9= 180/2= 90 (9 because you do 16-7 to find height of triangle)
Find the area of the rectangle=
7 x 20= 140
Add them up
140+90= 230cm squared

Answer:
24 blue cars
Step-by-step explanation:
Set up a proportion to solve this...

Now solve by cross multiplying...
120 = 5x
24 = x
