Answer:

  21 coins of ₹2

Step-by-step explanation:

Let x represent the number of ₹2 coins, and y the number of ₹5 coins. Then the total value of the coins is ...

  2x +5y = 77

and the relationship between numbers of coins is ...

  x = 3y

Substituting for x, we have ...

  2(3y) +5y = 77

  y = 77/11 = 7 . . . . simplify, divide by the coefficient of y

  x = 3(7) = 21 . . . . find x from the second equation

Ram has 21 of the ₹2 coins.

Brian buys 5 cookies and 1 bottle of water. The total cost is $8.75. If the bottle of water costs $1.25, which equation can be u
lubasha [3.4K]

Answer: $1.50/cookie

Step-by-step explanation:

Cookies = x

Water = y

5x + y = $8.75

y = 1.25

Plug in y-value into equation:

5x +1.25 = 8.75

5x = 8.75 - 1.25

5x = 7.50

x = 7.50/5

x = $1.50 for 1 cookie.
