Answer:
Try to look for the pattern.
As you can see on the first column, the last three numbers line up by +3 (12 to 15 to 18). Proof - 12 + 3 = 15 + 3 = 18.
So you go back by subtracting 3. 12 - 3 = 9 - 3 = 6 - 3 = 3
For the other column, the pattern is +17. Proof - 51 - 34 = 17, 102 - 85 = 17.
So do the same thing as in the first column.
Results:
3 17
6 34
9 51
12 68
15 85
18 102
Answer:
23, 24 and 25
Step-by-step explanation:
These are consecutive numbers that add up to 72.
First multiply 11 with 9 to get 99 and then 11 with d to get 11d
thus the answer is 99+11d.
Since ΔABC ~ ΔEDC, ∠B = ∠D.
Since both triangles appear to be similar, the corresponding angles are the same, and corresponding sides are the same or have the same ratio.
We can write an equation to resemble the problem:
8x + 16 = 120
Solve for x.
8x + 16 = 120
~Subtract 16 to both sides
8x + 16 - 16 = 120 - 16
~Simplify
8x = 104
~Divide 8 to both sides
8x/8 = 104/8
~Simplify
x = 13
Therefore, the answer is 13.
Best of Luck!
