Profits = 3.009(number of pizzas) - 77.131
Profits = 3.009(275) - 77.131 = 750.344
The third one is the product
2×-1 =-2
2×0=0
ans(-2 0)
So 9 more than 3 times a number, would be:
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5
your welcome!!!! :)
