The answer is 4 lawns because one fourth of 16 is 4 and the question is asking how many did he mow on main street.
The answer would be 56n^2 + 19n - 15
Multiply 8n with 7n to get 56n^2, then multiple 8n with 5 and you get 40n, then multiple -3 with 7n to get -21n, then -3 times 5 which gives you -15. Simplify and that is the answer you would get.
We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that x - y = 0.7 and x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us 2x = 1.7, and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use x + y = 1.
So now we have 0.85 + y = 1, so y = 1 - 0.85 = 0.15
The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).
Hope this helps!
Yes he is correct because u do have to multiple it
