In order to solve for this question, let's assign a couple variables.
The variable 't' will represent the number of two-point questions, and the variable 's' will represent the number of six point questions.
From the given, we can already form two equations:
t + s = 36
("An exam... contains 36 questions")
2t + 6s = 148
("An exam worth 148 points... Some questions are worth 2 points, and the others are worth 6 points")
Before we begin calculating anything, we can simplify the second equation we made, since all the numbers are divisible by 2:
2t + 6s = 148
t + 3s = 74
Now let's refer back to the first equation. We can subtract both sides by 's' (you could also subtract both sides by 't', but I personally think that this will make solving the equation less difficult):
t + s = 36
t = 36 - s
This effectively gives us a value for the variable 't'. We can assign this value back into our first equation:
t + 3s = 74
(36 - s) + 3s = 74
36 + 2s = 74
2s = 38
s = 19
Input 's' into our second equation to solve for 't':
t = 36 - s
t = 36 - 19
t = 17
There are 17 two-point questions and 19 six-point questions

Answer:
c. 8 1/3 cups
Step-by-step explanation:
3 1/3 * 2 1/2 = 25/3 or 8 1/3
(1, 22), (3, 18), (5,14), (6, 13), (8,5)
(1, 23), (3, 18), (5,14), (6, 11), (8,7)
you plot there on a graph. do you know how to place on a graph?
if not, the line going up and down is the x-axis and the line going side to side is the y-axis,
for example (4,7) it would be (x,y)
i really hope this helps :)
