Answer:
a
Step-by-step explanation:
The whole is 10/10 (consider to use the same denominator when comparing fractions) The half of 10/10 will be 5/10 which is not 4/10.
it's close to half but not the half
Answer: 55°
Step by step:
80 + x = 180
x = 100
Because the bottom of the figure is a line which equals 180°, so you would subtract 80 from 180 to get the angle on the other side of the line dividing the triangles.
Then, you would use the triangle sum theory which states that the angles of a triangle equals to 180.
100 + 25 + x = 180
125 + x = 180
x = 55°
So angle CBD = 55°
Answer:
x ≤8/5
Step-by-step explanation:
6x - 9 ≥ 11x - 17
Subtract 6x from each side
6x -6x-9 ≥ 11x - 17-6x
-9 ≥ 5x- 17
Add 17 to each side
-9+17≥ 5x - 17+17
8≥ 5x
Divide each side by 5
8/5≥ 5x /5
8/5≥ x
