Answer: 2b +2f =5----------(1)
3b +4f =8.5---------(2)
From eqn 1
2f = 5 -2b
f = (2.5 - b)
Put f =(2.5-b) in eqn 1
3b + 4(2.5-b) =8.5
3b +9 - 4b =8.5
-b = -0.5
b = $0.5
Step-by-step explanation:
'of' means muiptly
4/5 of a pizza
'a pizza' means 1 whole pizza
4/5 of 1=4/5
eats 2/3 of that share (meaning 4/5)
2/3 of 4/5=2/3 times 4/5=8/15
so she ate 8/15 of pizza
Ok so, we have the fact that 1.20 per mile Lets represent m as each additional mile so we have 1.20m which is That much per additional mile So For the first 5 functions we have f(1) = 20 f(2) = 20 f(3) = 20 f(4) = 20 f(5) = 20 Only for the first 5 miles though, since it is a flat fee. So for the additional miles we go back to what I said in the first Paragraph. 1.20m That is for additional miles, so that will be added to 20 So if you travel more than 5 miles the function looks like this: f(x) = 20 + 1.20m So the first 5 miles it is: f(x) = 20 For 7 mles the function would look like: f(7) = 20 + 1.20(2) It is a 2 because it is the additional mile, which is 2 hope this helps
