HELP ME PLS!!!! asap!!!!
Andrews [41]

Answer: Calvin has 13 quarters.


Step-by-step explanation:

Let Calvin have  x quarters.  

therefore amount of Calvin =  0.25 x    [ 1 quarter =  $0.25 ]

Number of dimes for Sara = x  

      [ Given that number of dimes of Sara = number of  quarters of Calvin

Amount of dimes for Sasha = 0.1x  [ 1 dime = $0.1 ]

Amount of Sasha without dime =  $1.95  [ given]

total amount of Sasha = 1.95 =+ 0.1x

Since amount of Calvin and Sasha is same  therefore

        0.25x  = 1.95 +0.1x

      0.25x -0.1x = 1.95

       0.15x = 1.95

           x = \frac{1.95}{0.15}

           x = 13

x1= -6

y1 = -17

x2 = -8

y2 = -19

by applying the formula

Square root of ( -8 - (-6))^2 + ( -19 - (-17))^2

Square root of (-8+6) + (-19+17)^2
