Answer:
26
Step-by-step explanation:
Let the peter's number be represented x
Given that
1. if you subtract 19 from my number
writing it mathematically it will be x -19
2. multiply the difference by -3
it can be written as
since difference is x-19
multiplied the difference with -3
-3(x-19)
3. the result is -21
-3(x-19) = -21
dividing both side by -3
-3(x-19)/-3 = -21/-3
x-19 = 7
adding 19 both sides
x-19 + 19 = 7 + 19
x = 26
Thus, peter's number is 26.
Point D is located between 35 and 40 so the possible answers are 36, 37, 38, and 39.
Point D is closer to 40 than 35, so we narrow down the option to 38 or 39.
39 would have been really close to 40, so Lara's statement is reasonable to say 38 is point D.
Answer: 51 inches
