When something bisects an angle, it cuts that angle in half. This means that ray BD cuts angle ABC in half. Therefore, angle ABD, which is formed by cutting the angle in half, is equal to angle CBD, which is also formed by cutting the angle in half. Because of this, you have to set the equation equal to each other.

9x-18=5x+2

Combine like terms. Add 18 to both sides.

9x=5x+20

Combine like terms. Subtract 5x from both sides.

4x=20

Divide 4 on both sides.

x=5 degrees

1. Chelsea can paint a fence in 9 hours, and Greg can paint the same fence in 7 hours. How long does it take them to paint the f

Leto [7]

Answer:

3.9 hours
90 mph

Step-by-step explanation:

The sum of the rates of painting, in fences per hour, is ...

1/9 + 1/7 = (9+7)/63 . . . . fences per hour

The total rate in hours per fence is the inverse of that:

63/16 = 3 15/16 ≈ 3.9 . . . hours to paint the fence

The relevant relationship is ...

distance = speed × time

Let t represent Tom's speed in miles per hour. Then George's speed is (t-36). They both have traveled the same total distance at the point where Tom catches up.

(2+3)(t-36) = 3t

2t = 180 . . . . . . . add 180-3t

t = 90 . . . . . . divide by 2

Tom's average speed is 90 miles per hour.

A one-year membership to the gym costs $362. When signing up, members pay $54 for the first month, then the remaining part is ma

Neporo4naja [7]

<u><em>Answer:</em></u>

A member is expected to pay $28 per month after the initial month

<u><em>Explanation:</em></u>

<u>We are given that:</u>

The total cost per year (12 months) is $362

The member is required to pay $54 during the first month

<u>This means that:</u>

Remaining cost = Total cost - Payment made the first month

Remaining cost = 362 - 54 =$308

<u>We know that</u> the member will pay this remaining cost in a duration of 11 months (we exclude the first month of the year since he already paid $54 in it)

<u>We also know that</u> payments in each of these 11 months will be equal

<u>This means that:</u>

Payment per month = $\frac{308}{11} = $28$ dollars

Hope this helps :)
