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
Answer:61
Step-by-step explanation:
Z+Z-11=Z+50
2Z-11=Z+50
Collect like terms
2Z-Z=11+50
Z=61
Yea i gusse is this a question????????????????????????????????????????????????????????????..............................................................
Answer:
lets start with the easy equation. X+Y=60. so we take 60 and subtract Y to get X by itself. meaning X = 60-Y. every time we see X replace with (60-Y).
X + 5Y = 100 change to
60-Y+5Y = 100
5Y - Y = 4y.
60+4Y = 100. 100 minus the 60 = 40. 4Y=40. divide by 4. Y = 10. ok so now we solve for X. X + Y (or 10) = 60. 60-10 = 50. X = 50.
