14+5x=3(-x+3)-11

14+5x=-3x+9-11

14+5x=-3x-2

add 2 to both sides

16+5x=-3x

subtract 5x from both sides

16=-8x

divide both sides by -8

-2=x

Hope this helps! :)

Two integers, a and b have a product of 15. what is the least possible sum of a and b?
Neporo4naja [7]
If they're integers, that means they can't be fractions (such as 15/2 and 2).

So the only couples of integers that, when multiplied, result in 15 are:

1 and 15
5 and 3.

(there are no other possibilities as both 5 and 3 are not divisible further).
The smaller of the two sums (15+1; 5+3) is 5+3=8.

The least possible sum of a and b is 8.

Question 3 / 5
Allisa [31]

There are 10 seats in ferris wheel of love.

One couple can fit in to one seat. That means 1 couple per seat.

Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.

The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means \frac{60}{2} = 30 minutes.

So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.

We have got in 1 minute there is 1 couple.

So in 30 minutes there are (1)(30) couples = 30 couples.

We have got the required answer here.

There are 30 couples who took a ride in the ferris wheel of love.
