If $1 is 75 yen and there is $25, multiply 25*75 to get the total amount of yen. 25*75 = 1875 yen was what he had to pay
3x+2x=5y
1.Collect the like terms (5x=5y)
2.Divide both sides by 5 (x=y)
Final solution is x=y
OR
3x+2x=5y
1.Substitute y=0
2. Solve the equation 3x+2x=5*0
Final solution is x=0
Answer:
12-3y-2x+x+2x = x-3y+12
3x+2y-2x+y+12 = x+3y+12
4y+3y+3x-6y-10-2 = 3x+y-12
x+3y+2x-3x+7+5 = 3y+12

Answer:
The required function is: ![W(t) = 2t+8](https://tex.z-dn.net/?f=W%28t%29%20%3D%202t%2B8)
Step-by-step explanation:
The weight of the baby increases 2lbs per month which means that it is a linear function.
Now given that the initial weight was 8lbs it will remain constant.
Let t be the number of months and as the weight gain is 2 lbs per month, 2t will be the weight gain after t months.
The function can be written as:
![W(t) = 2t+8](https://tex.z-dn.net/?f=W%28t%29%20%3D%202t%2B8)
Hence,
The required function is: ![W(t) = 2t+8](https://tex.z-dn.net/?f=W%28t%29%20%3D%202t%2B8)
