The answer to a8 of the sequence will be 8. I found this out by multiplying the subtraction value (.25) by the number in the sequence needed (8) to get 2. Then, I subtracted the starting number with 8 to get 8 (10-2 = 8). Hope this helped :)
Swap the shortest and longest pencil's places. You don't have to move the middle pencil.
Both angles are complementary and add up to 90 degrees. If you do that in an equation it should be like this:
2x + 14 + x + 7 = 90
Simplify:
3x + 21 = 90
3x = 69
X = 23
Now just plug that into angle CBD and you get:
2(23) + 14 = y
46 + 14 = y
60 = y
Angle CBD is 60 degrees
Answer:
B. 30
Step-by-step explanation:
the equation looks like 22 - x = -8 and 22 - 30 is negative 8
