-30c-6= -9c-3
-30c+9c= -3+6
-21c= 3
c= -3/21
c= -1/7
Answer:
VW = 8
Step-by-step explanation:
Because this trapezoids are similar
PS : TW = PQ : TU = QR : UV = RS : VW
We can take for example this equation
QR : UV = RS : VW
6 : 4 = 12 : VW
6*VW = 4*12
VW = 4*12/6 = 8
The best way to see what is happening in both situations is to create a table showing the new elevation after each minute.
Please see the attached picture for the work.
After five minutes, both balloons will be at the same height.
M=20 since 27-m=7 it means that 20+7=27
The area of a triangle is determined by the formula: Base x Height * 1/2
You'll need to assign a base to the triangle. Based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). The distance between any two numbers is found by just subtracting them. Here, you should subtract the x values to find the distance of this side.
2 - (-2) = 4.
So the distance (aka the length of the base) is 4. The height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). We should subtract the y values this time to find the height/distance.
4 - 1 = 3
So the height is 3.
Base = 4
Height = 3
