Answer:

  a = 9/2

Step-by-step explanation:

In order for the equation to be true, the value of the scalar multiplier must be ...

  15/3 = -10/-2 = 35/7 = 5

So, you're solving ...

  (2/3)a + 2 = 5

  (2/3)a = 3 . . . . . . subtract 2

  a = 9/2 . . . . . . . . multiply by 3/2

Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2
Anna [14]

Answer:

100 Rs 5 coins and 50 Rs 2 coins

Step-by-step explanation:

Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2 coins

Let x be the number of 5 coins

and y be the number of 2 coins

The number of Rs.5 coins are twice as many as Rs.2 coins

x=2y

5x+2y=600

Replace x with 2y

5x+2y=600\\5(2y)+2y=600\\10y+2y=600\\12y=600\\y=50

x=2y\\x=2(50)\\x=100

So 100 Rs 5 coins and 50 Rs 2 coins

kykrilka [37]
Hiya!

So, 6 billion is 100%. 50% is 3 billion. 25% is 1.5 billion. 20% must be 1.2 billion because 1.2 × 5 is 6. I know that 20% is 1/5 of 100%, and that's how I got my answer.

If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
