There are 45 new houses being built in a neighborhood. last month 1/3 of them were sold. this month 2/5 of the remaining houses were sold. how many houses are left to be sold

18

Step-by-step explanation:

First we find out how much were sold last month:

1/3 x 45 = 15

Then we know that there are still 30 houses left to sell because 45 - 15 = 30

The houses that were sold this month:

2/5 x 30 = 12

Because we know that 12 more houses were sold, the remaining would be  30 - 12, which is 18

it has the same slope and a different y-intercept

hope this : )

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
