Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions

Answer:
Suzi's elevation in the hike is 37 feet.
Step-by-step explanation:
We are given the following in the question:
Position of Suzi in the starting of hike = 200 feet below sea level
= -200 feet
The negative sign shows below sea level.
Position of Suzi in the end of hike = -163 feet
Change in elevation from the beginning of Suzi's hike to the end of the hike
= Position of Suzi in the end of hike - Position of Suzi in the starting of hike
Thus, Suzi's elevation in the hike is 37 feet.
Since one watermelon seed is 0.4 long, you can multiply 0.4 by 112
0.4 x 112 = 44.8
So it will be 44.8 long
