Plz help me with this practice test this is a practice for our final test I have on Monday please help me with all 5 I have really bad anxiety and stress about this

Step-by-step explanation:

1) a + $5.92 = $12.29

subtract 5.92 from both sides

a = $6.37

Third option, a = $6.37

2) Multiply the equation by j to get it to the left side

42 = 6j

Divide both sides by 6

42/6 = 7

7

3) 9 + 8 = 17           No

   9 x 3 = 27          Yes

   9 + 3 = 12           No

   9 - 5 = 4             Yes

   9/3 = 3                No

4) 15.32 + c = 29.00

c = 13.68 is the most expensive you can go, so it would be the soccer ball, since it is the most expensive item under 13.68.

5) 6 x 6 = 36 .    False

   5 + 6 = 11 .       True

   6/2 = 3 .          True

 17 - 6 = 11           True

Hope this helps :)
