Answer:
-6
(I don’t understand what you mean by on & 5 but..)
Step-by-step explanation:
The two negatives (the -(- ) cancel each other out and make a postive, so
-18 + 12 = -6
All of them except B and C. Probabilities must add to 1 and none of the p's can be negative
524 cm cubed
Explanation: 4/3 x pi x 5cubed = 523.599cm cubed rounded to 524cm cubed
2a+1 + 3a+2 +5a-9 you would start by combining like terms
2a+3a+5a= 10a
1+2-9= -6
10a-6=94
then subtract 94-6=88
then divide 88 by 10= 8.8
a=8.8
Just set the equations equal to each other
