Question

I need help with this paper

Answer 1

Answer:

1st one:

37 - 25 = 12

2nd one (to the right of the one on the top-left):

(19 - 10) - 7 = 2

3rd one (below the one of the top-left):

Since BD = 13 and CD = 10, BC must equal 3.

AC would equal the sum of 8 and 3.

8 + 3 = AC

11 = AC

4th one:

Not exactly sure what you want to find here, add more info.

But if you want to find the middle or mid-point:

10 + 3x + 5 = 25

15 + 3x = 25

3x = 10

Divide by 3 on both sides:

x = 3.33 or 31/3 or 10/3

5th one (bottom-left):

*First find x*

9 + x + 2x - 3 = 30

6 + 3x = 30

3x = 24

Divide both sides by 3:

x = 8

*Now that you have x, you can find the length of DE:

2(8) - 3 = DE

16 - 3 = DE

13 = DE

Answer 2

What grade is this?..
