Can someone help me with this

a = 17

c = 9

Step-by-step explanation:

2a + 3c = 61

3a + 5c = 96

3a = 96 - 5c   (solve for 'a'. Then you can substitute)  

a = 32 - c

2(32 - c) + 3c = 61     (Substitute)

64 - c + 3c = 61        ( = 3 . So subtracting, adding a negative, leaves )

- c= -3  

c = 9

2a + 3(9) = 61

2a + 27 = 61

2a = 34

a = 17

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%
