Kendra has $6.00 in dimes and quarters. If she has 2 times as many quarters as dimes, how many of each coin does she have?

r-ruslan [8.4K]

Make a system of equations.

$\sf0.10d+0.25q=6$
$\sf~q = 2d$

Plug in 2d for 'q' in the first equation:

$\sf0.10d+0.25q=6$

$\sf0.10d+0.25(2d)=6$

Multiply:

$\sf0.10d+0.50d=6$

Combine like terms:

$\sf0.60d=6$

Divide 0.60 to both sides:

$\sf~d=10$

Now plug this into any of the two equations to find 'q':

$\sf~q = 2d$

$\sf~q = 2(10)$

$\sf~q = 20$

So she has 10 dimes and 20 quarters.

Because the triangles are similar

ac/pr=bc/qr
8/pr=10/4

Solve for y and x 2+3x-1=4y And 2x-3=y

Natasha_Volkova [10]

Answer:

x = 2.6, y = 2.2

Step-by-step explanation:

if 4y = 2 + 3x - 1 and

y = 2x - 3,

4y = 2 + 3x -1 and 4y = 8x - 12 so

8x - 12 = 2 + 3x - 1

so 5x - 12 = 1,

5x = 13,

x = 2.6

If x = 2.6,

y = 5.6 - 3

so y = 2.2
