Answer:

company N built 10 more brick houses

Step-by-step explanation:

if company M builds 2x as many wooden houses as the do brick houses that would be 1/2 of 100 which is 50, and the ratio of wood houses to brick houses for company M is 5:3, 5x20=100  3x20=60.   60-50=10

Answer:

10 houses

Step-by-step explanation:

If Company M builds half as many brick houses as wood houses, then if this company builds 100 wood houses, it builds 50 brick houses.

For Company N, create a linear equation showing the relationship between wood houses (x) and brick houses (y).  For every increase in x by 5, y increases by 3:

y = (3/5)x

Therefore, when x = 100:  y = (3/5)(100) = 60

So Company N builds 60 brick houses when it builds 100 wood houses.

Company N - Company M = 60 - 50 = 10 houses

Therefore, Company N built 10 more brick houses than Company M.
