There are 60 new houses being built in a neighborhood. last month, 2/3 of them were sold. this month, 1/4 of the remaining houses were sold. how many houses are left to be sold.

15

Step-by-step explanation:

2/3 of 60 = 40 houses sold.

60 - 40 = 20

That leaves 20 houses left.

1/4 of 20 is 5 houses sold.

That leaves 15 houses left.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
