Find x. PLEASE HELP . Will mark Brainliest!

x = 23

Step-by-step explanation:

This is a polygon. Since the rule for finding the number of degrees in a polygon is n - 2, we can find our answer for x.

There are 7 sides, so 7-2 =5 * 180 degrees in a heptagon. (7 sided figure):

180 * 5 = 900, so there are 900 degrees in this heptagon.

Now, to solving:

We can set up an equation like this:

7x + 2x + 8x + 10x + 8x + 35 + 60 = 900.

Combining like terms:

35x + 35 + 60 = 900

Simplifying:

35x + 95 = 900.

We subtract 95:

900 - 95 = 805.

Now we have:

35x = 805.

Dividing both sides by 35 gives:

x = 23 as our answer.

Check:

If we have solved correctly, we should have that 35 * 23 + 95 = 900:

35 * 23  = 805. 805 + 95 = 900.

So we are correct.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
