Hello there.

Question: <span>Jamie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded six baseball cards and nine football cards. Based on these data, what is, most likely, the number of baseball cards in the deck?
12
15
24
30

Answer: You could use ratio to figure this out.
6:9 = 15
6 baseball for 9 football cards
Divide the total by the amount already known
60/15 = 4
Multiply all values by 4.
6 x 4 = 24.
9 x 4 = 36.

In short, the answer is 24.

Hope This Helps You!
Good Luck Studying ^-^

A used bookstore sells hardback books and paperback books.A hardback book costs $11, including tax.A paperback book costs $5, in
Ket [755]

Answer:

D.5

Step-by-step explanation:

You can write the following equations from the information given:

y=x+3 (1)

11x+5y=47 (2)

x is the number of hardback books

y is the number of paperback books

You can replace (1) in (2):

11x+5(x+3)=47

11x+5x+15=47

16x=47-15

16x=32

x=32/16

x=2

Then, you can replace the value of x in (1) to find the value of y:

y=2+3

y=5

According to this, the answer is that Jamal bought 5 paperback books.

Can you help me solve systems of equations by elimination step by step<br> -5x+9y=-12<br> 3x+2y=22
Sergio039 [100]

Answer:


Step-by-step explanation:

First solve -5x+9y=-12 for x:


-5x+9y=-12

-5x+9y-9y=-12-9y

-5x=-12-9

-5x=-9-12

-5x/-5=-9/5-12/-5

x=9/5y+12/6


Substitute x into an equation


3(-9/5y+12/6)+2y=22

37/5y+36/5=22

37/5y+36/5-36/5=22-36/5

37/5y=74/5

37/5y/37/5=74/5/37/5

y=2


Substitute y in x=-9/5y+12/6


9/5(2)+12/6

x=6


Solution Set: (6,2)
