5. no because each spinner is not the same size. it's not divided equally. 6. yes because a cube has 6 faces, so 1 on each is even. 7a. 12% 8. the bag with 25 tiles has a 40% chance of blue tiles and the bag with 250 tiles has a 30% chance, so the chances of picking a blue tile from the 250 tile bag is lower
Answer:
x = 0
Step-by-step explanation:
The axis of the symmetry has the same x coordinate of the vertex
V (x) = -b/2a
in both equations b is equal to 0 and a 0/a number different from 0 gives always 0 as a result
Add the fractions together
1/7 + 1/2
find a common denominator
1/14 + 1/14
= 2/14 + 7/14
= 9/14
Answer:
x = 23
Step-by-step explanation:
These are supplementary angles so the sum of those angles add up to 180:
3x + 16 + 5x - 20 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23
