Answer:

x=3

Step-by-step explanation:

I guessed and checked which x value would make ABC proportional to DBE. If x=3, than DB=8 which is double BE. If x=3, than AB=14 which is double BC. Since it is proportional, It should be correct. I don't remember the actual way you solve this with a formula but this makes sense to me.

Answer:

x=3

Step-by-step explanation:

We can use ratios to solve since the triangles are similar

x+5                   4

------------ = ---------------

x+5 +2x          4+3

Simplifying

x+5                   4

------------ = ---------------

3x+5             7

Using cross products

7(x+5) = 4(3x+5)

Distribute

7x+35 = 12x+20

Subtract 7x from each side

35 = 5x+20

Subtract 20 from each side

15 = 5x

Divide by 5

3 =x

GH has a midpoint at M (5,9). Point H is at (8,9). Find the coordinates of point G
natta225 [31]

Answer:

(2,9)

Step-by-step explanation:

The midpoint of a point is halfway between two points. The distance between the midpoint and point H is 3 because the distance from 5 to 8 is 3. Therefore 3 away from 5 would be 2.

Chase answers 3/4 of his math questions correctly. There were 40 questions on the test.
lawyer [7]
Since there were 40 questions on a math quiz and he got 3/4 correct he got 30 correct and 10 incorrect.
A simple way to solve this is to add a zero to the end of each number in the fraction since there is 40 questions so it goes from 3/4 correct to 30/40 correct.
Hope this helps!!
