I think you should combine like terms
Answer:
Step-by-step explanation:
<u>Proportional relationship equation:</u>
- y = kx, where k- constant of proportionality
<u>Use the given point to work out the value of k:</u>
<u>In our case the equation is:</u>
- v = 5.6m, where v- volume, m- mass
What was your other question
The equation is $130 + $31.67x = 500
Subtract 130 from both sides $31.67x = $370
Divide $31.67 from both sides
X=11.68
BUT
you can’t have .68 of a day so the answer is 11 days.
The answer is $4.14.
Hope this helps!!
