Answer:
42
Step-by-step explanation:
4x + 2 = 1/2 (4x + 44) Be careful how you do this. I have multiplied both sides by 2
2(4x + 2) = 4x + 44 Remove the brackets (distributive)
8x + 4 = 4x + 44 Subtract 4x from both sides
8x-4x + 4 = 44
4x + 4 = 44 Subtract 4 from both sides
4x + 4-4 = 44-4
4x = 40 Divide by 4
4x/4 = 40/4
x = 10
The mid line is 4x + 2
The mid line is 4*10 + 2
The mid line is 40 + 2
The mid line is 42
The base is 4x + 44
The base is 4*10 + 44
The base is 40 + 44 = 84 which is twice the midline. I did this just to show it is twice as big as the midline.

How do you find the area of a triangle
To find the area of a triangle, you need to know the formula of the triangle to work it out. The following is the formula of the triangle:
H - height
B- Base
You need to multiply the base and height and divide it by 2.
Lets solve a question!
Find the area of a triangle with a base of 32mm and a height

of 35mm
Area =

The change in value over 4 years is
$22,000 - 30,000 = -$8,000
so the average change in value per year is
-8000/4 = -2000
(100 5/8) / (14 3/8)
(805 / 8) / (115/8) =
805/8 * 8 / 115 =
805 / 115 =

Answer:
0.3056 or 30.56%
Step-by-step explanation:
The volume of the grapefruit with the peel is:

When removing the peel, the grapefruit diameter becomes 10 cm (take out 1 cm of peel from each side). The volume of the grapefruit without the peel is:

The percentage of the volume correspondent to the peel is given by the difference between both volumes, divided by the total volume:
30.56% of volume of the grapefruit is the peel.
