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

45 new houses...
1/3 were sold1/3(45) = 45/3 = 15 houses soldleaving 45 - 15 = 30 houses left. 1/5 of remaining houses sold1/5(30) = 30/5 = 6...so 6 more houses were soldleaving 30 - 6 = 24 houses

24 houses are left <==

45(1-1/3)(1-1/5)

45(2/3)(4/5)

(45*2*4)/(3*5)

360/15

24

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
