Max has a collection of 99 dimes and pennies worth $4.41. how many pennies does he have?

Max has a collection of 99 dimes and pennies worth $4.41.

1 dime = 10 cents

1 penny = 1 cent

1 dollar = 100 cents so 4.41 dollars = 4.41* 100 = 441 cents

Lets 'd' be the number of dimes

Let 'p' be the number of pennies

dimes + pennies = 99

So equation-1 becomes d + p = 99

Worth of dimes and pennies is 440 cents

Worth of 'd' dimes is 10d

Worth of 'p' pennies is 1p

So the equation-2 becomes 10d + 1p = 441

Solve both the equations

10d + 1p = 441

d + p = 99

Multiply the second equation by 10 and then subtract it

10d + 1p = 441

-10d -10p =-990

-9p =- 549

Divide by -9 on both sides

So p = 61

Max have 61 pennies .

ummm seems that u didnt post the attachement !

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
