NWEA Math 4 โ Questions and Answers
Question 1: On a coordinate plane, what are the coordinates of a point 3 units right and 4 units down from the origin?
- (โ3, 4)
- (3, 4)
- (3, โ4) (Correct answer)
- (โ3, โ4)
Correct answer: (3, โ4)
Right means positive x (+3) and down means negative y (โ4), giving (3, โ4).
Question 2: Simplify: 4(2x + 3) โ 5x
- 3x + 3
- 3x + 12 (Correct answer)
- 3x + 7
- 8x + 12
Correct answer: 3x + 12
Distribute: 8x + 12 โ 5x = 3x + 12.
Question 3: A bag contains 5 red marbles and 3 blue marbles. What is the probability of randomly picking a blue marble?
- 3/5
- 5/8
- 3/8 (Correct answer)
- 1/3
Correct answer: 3/8
There are 3 blue out of 8 total marbles, so P(blue) = 3/8.
Question 4: What is the volume of a rectangular prism with length 5, width 4, and height 3?
- 12
- 20
- 47
- 60 (Correct answer)
Correct answer: 60
Volume = length ร width ร height = 5 ร 4 ร 3 = 60 cubic units.
Question 5: Which of the following is a rational number?
- โ2
- ฯ
- โ9 (Correct answer)
- โ5
Correct answer: โ9
โ9 = 3, which is a whole number and therefore rational; the others are irrational.
Question 6: A recipe calls for 2/3 cup of sugar. If you want to make 1.5 times the recipe, how much sugar do you need?
- 3/4 cup
- 1 cup (Correct answer)
- 1 1/3 cups
- 1 1/2 cups
Correct answer: 1 cup
2/3 ร 1.5 = 2/3 ร 3/2 = 6/6 = 1 cup.
Question 7: The table shows: x = 1โy = 5, x = 2โy = 8, x = 3โy = 11. Which equation represents this relationship?
- y = 2x + 3
- y = 3x + 2 (Correct answer)
- y = 4x + 1
- y = x + 4
Correct answer: y = 3x + 2
The pattern increases by 3 each time and y = 3(1) + 2 = 5, confirming y = 3x + 2.
