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.

A rectangle has a volume of 912 cubic meters. It has a length of 19 meters and a width of 12 meters. Which equation can be used
Nimfa-mama [501]
The answer would be B because LWH=V, so taking the information given, L(19) times W(12) would equal 228 and 228 times the H would give us volume so B
Hope this helped ;)

a bottle of hand lotion is on sale for $2.25 . If this price represents a 50% discount from the original price , what is the ori
N76 [4]
So 2.25 is 50% of the original price
let's write original price as x
50% of x = 2.25
0.5 * x = 2.25
divide both sides by 0.5
x = 4.5

The original price is 4.5

To check:
50% * (4.5) =?= 2.25
0.5 * 4.5 =?= 2.25
2.25 = 2.25

Hope this helps.
