Hello!

You add the amount of sections have red or purple

2 + 2 = 4

Put this over the amount of sections

4 / 10 = 0.4

Multiply this by the amount of times he spins the spinner

180 * 0.4 = 72

The answer is about 72 times

Hope this helps!

find the value of x if A, B and C are collinear points and B is between A and C. AB= 6x, BC= x-5, AC= 23
Irina18 [472]

Answer:

x=4

Step-by-step explanation:

AB + BC = AC

AB= 6x, BC= x-5, AC= 23

Substituting what we know

6x + x-5 = 23

Combine like terms

7x -5 = 23

Add 5 to each side

7x-5+5 =23+5

7x = 28

Divide each side by 7

7x/7 = 28/7

x=4
