Which of these is a simplified form of the equation 8y + 4 = 6 + 2y + 1y?
Gelneren [198K]

Answer:

5y=2

Step-by-step explanation:

8y + 4 = 6 + 2y + 1y

Combine like terms

8y+4 = 6+3y

Subtract 3y from each side

8y-3y+4 = 6+3y-3y

5y +4 = 6

subtract 4 from each side

5y+4-4 = 6-2

5y=2

Paul, Linda, and Aaron make handmade cards. Paul can make 1 card for every 3 cards Linda makes. Linda can make 3 cards for every
patriot [66]

Answer:

Linda makes 3 more cards than Paul.

Step-by-step explanation:

Let's express the affirmations into equations:

Paul (P) can make 1 card for every 3 cards Linda (L) makes:

\frac{P}{L} = \frac{1}{3}

3P = 1L            (1)

Linda can make 3 cards for every 2 cards that Aaron (A) makes:

\frac{L}{A} = \frac{3}{2}  

2L = 3A          (2)        

During a week, Aaron makes 72 cards, hence the number of cards of Linda and Paul can be calculated as follows:

From equation (2):

L = \frac{3}{2}A = \frac{3}{2}72 = 108

Now, from equation (1):

P = \frac{1}{3}L = \frac{1}{3}108 = 36

Finally, the number of cards that Linda makes more than Paul is:

\frac{L}{P} = \frac{108}{36} = 3

Therefore, Linda makes 3 more cards than Paul.

I hope it helps you!
