Circumference = pi*d
P=3.14 d=16
The general form is y = mx + c
where m = slope and c is the y intercept
Here it is y = -4x - 1 (answer)
You would -7 cents from the 1.50 so it was 1.43
Proportions can sort of act like ratios. I would solve it like a chart. $2 for 4 oranges. $3 for 6 oranges. That shows numbers in a proportion or a group. The base ratio is $1 for 2 oranges. Ratios can be fractions too. If you multiply 2 to the $1 to make it $2, the number of oranges you get increases too. Hope this helps!
