3x - 8y = 24
y = x - 8
plz show work

the solution is (8, 0)

Step-by-step explanation:

Solve this system of linear equations by substitution.  We are told that y = x - 8.  Substitute x - 8 for y in the first equation:

3x - 8(x - 8) = 24

Performing the indicated multiplication, we get

3x - 8x + 64 = 24.  Combining like terms results in:

-5x = -40, so that x = 8.

y = x - 8 (given above), so in this case y = 8 - 8 = 0

Thus the solution is (8, 0)

10

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
