You break up the 207 into smaller numbers you can work with. 9 can go into 20 a maximum of 2 times, so you subtract 2*9 or 18 from 20. Then, you bring down the 7. 9 goes into 27 exactly 3 times, so you have 9*23=207.
Answer:
-43
Step-by-step explanation:
Follow PEMDAS as well as the left -> right rule.
Note that: PEMDAS =
Parenthesis

Subtraction
First, solve the multiplication:
23 + (5 * 3) - 100 + 19
23 + (15) - 100 + 19
Simplify. Follow the left-> right rule:
(23 + 15) - 100 + 19
38 - 100 + 19
(38 - 100) + 19
-62 + 19 = -43
-43 is your answer.

3 comes in the range 3 =< x <= 12
so its x + 4 = 3 + 4 = 7
B
Distance from start to look out point is calculated below
d1 = 8 3/4 miles - 0 miles = 8 3/4
Distance from look out point to giant boulder is,
d2 = 8 3/4 miles - 4 1/4 miles = 9/2 miles = 4.5 miles
Thus, the answer is equal to 4 1/2 miles. The answer is letter C.
