X+8=-2<br><br> O A. x= 10<br> OB. x=-6<br> O C. x=6<br> OD. x= -10
MaRussiya [10]

Answer: option D

Step-by-step explanation:

X+8=-2

    x= -2-8 (you should make x the subject so you switch the +8 to the other

    x= -10                                                                   side which becomes -8)    

so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D

Alborosie
First pear            Second pear      probability

green (3/7)---------green (2/6)         (3/7)*(2/6) = 1/7
                  ---------red (4/6)             (3/7) *(4/6) = 2/7

red (4/7)-------------green (3/6)        (4/7)*(3/6) = 2/7
