Answer:
2x+3y=170.......1
1x+5y=225.......2
multiplying equation 2 by 2 and subtracting eq.1 &2
2x+3y-2x-10x=170-225
-7x=-55
x=55/7
55/7+5y=225
5y=225-55/7
y=1520/(7×5)=304/7
Answer:
or
Step-by-step explanation:
As mentioned at the top of the diagram, one square is equal to three feet (). If the dimensions are 18x18, we can divide eighteen by three to get six. (We can also count the squares on the graph, but this wouldn't be very fun if the model were bigger and it'd take a long time.) So, this means six squares is equal to eighteen feet ().
