SOS WHAT IS THE SQUARE ROOT OF 144/256?
tangare [24]
The square root is  \sqrt{\frac{144}{256}} = \frac{3}{4} Just square the top and bottom of the fraction. \sqrt{144} = 12 and \sqrt{256} = 16 so we have 12/16 and then we reduce to 3/4

I think of a number double it add 15 my number is 21 what number was i thinking about
AleksandrR [38]

Hello from MrBillDoesMath!

Answer:

3

Discussion:

Let the number be "n",

2n + 15  = 21          =>  subtract 15 from both sides

2n = 21 - 15 = 6     =>   divide both sides by 2

n = 6/2 = 3

Check: Start with 3. Double it (gives 6), add 15 to it ( 6 + 15)  which gives 21/

Thank you,

MrB
