Brandon has a cup of quarters and dimes with the total value of $3.80. the number of quarters is 4 less than twice the number of dimes. how many quarters and how many how many dimes does brandon have

Dimes = 8 and

Quarters = 12

Step-by-step explanation:

Total value = 380 cents

let dimes be x

quarters be 2x - 4

100 pennies = $1

1 dime = 10 pennies

1 quarter = 25 pennies

Therefore;

$ 3.78 = 378 pennies

10x+25(2x-4)=378

10x + 50 x - 100 = 378

60 x = 378 + 100

60 x = 478

     x = 478/60

        = 7.9667

        ≈ 8

Therefore;

Dimes = 8 and

Quarters = 12

1.5%

step-by-step explanation:

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
