WHAT IS THE TENTH DIDGIT IN THE QUOTIENT 120 / 11?
A. 0 B. 1 C. 8 D.9
I CHOOSE 9 THATS WHAT I GOT IN LONG DIVISION.
THE TEMPERATURE ON mARS REACHES 27DEGREE CELSIUIS DURING THE DAY AND
125 DEGREE CELSIUS AT NIGHT. WHAT IS THE AVERGE TEMPERATURE?
NOT SURE HOW TO DO THIS?
27  125 =
WHICH OF THE FOLLOWING STATEMENTS IS ALWAYS TRUE?
1. A NEGATIVE INTEGER PLUS A NEGATIVE INTEGER EQUALS A NEGATIVE INTEGER.
2. A NEGATIVE INTEGER MINUS A NEGATIVE INTEGER EQUALS A NEGATIVE INTEGER.
A. 2 ONLY B. BOTH 1 AND 2
C. 1 ONLY D. NEITHER 1 OR 2
WAS THE TENTH DIGIT 9 CORRECT IN FIRST QUESTION?
FOR 2ND QUESTION AVERAGE TEMPERATURE I GOT
27 + 125 = 76
FOR LAST ONE: 3  (9) = +6
SO THE ANSWER WOULD BE : C 1 ONLY IS TRUE  IS THAT CORRECT NOW?
Can you check if I have right now?

120/11 = 10.90909091.
My answer is 1.
Tavg. = (27 + (125)) / 2 = 49C.
C. 1 only. 
120/11 = 10.9090909090909090_
Without rounding, the tenth digit is 0.
1. Range from +27 to  125, therefore average (27+125)/2 = 76. Go 76º up from 125º or down from 27º.
2. 2(1) = 2+1 = 1
