Answer:

-1.8 =x

Step-by-step explanation:

12(x+3)=-8x

Distribute

12x +36 = -8x

Subtract 12x from each side

12x-12x +36 = -8x-12x

36 = -20x

Divide each side by -20

36/-20 = -20x/-20

-9/5 = x

Changing to decimal form

-1.8 =x

astra-53 [7]

Answer:

A.

\dfrac{x}{195}=\dfrac{100}{130}

B. 150

Step-by-step explanation:

Let x be the number of people at the club last year.

The attendance of your club increased by 30% from last year. This means that if the last year attendance was 100%, this year attandance is 100% + 30% = 130%

Thus,

x people - 100%

195 people - 130%

A. Write a proportion:

\dfrac{x}{195}=\dfrac{100}{130}

B. Cross multiply:

130\cdot x=100\cdot 195\\ \\130x=19,500\\ \\13x=1,950\\ \\x=\dfrac{1,950}{13}=150

Jim decides to start a small nonprofit business of renting out motor scooters to help out his area residents. He puts in his own
Deffense [45]
First, find the expected number of scooters rented per month:

As the data is symmetrical, E(X) (the expected value) is the middle value. So, on average, 2.5 scooters should be taken per month.

His total costs were 5 * 3000 = $15,000

So, to break even, he needs to make $15,000.

He will be selling for 5 years, or 60 months.

As a result, he needs to make 15000/60 = $250/month

As he is selling 2.5 scooters on average, he needs to rent each for:

$250/2.5 = <u>$100/month</u>
