Natural numbers are also called a. Non-negative integers 2. The most fundamental system of numbers b. Positive integers 3. Counting numbers are also called c. Real numbers 4. All points on a number line represent a set of d. Natural numbers [1] 1-c 2-d 3-b 4-a [2] 1-c 2-d 3-a 4-b [3] 1-b 2-c 3-d 4-a [4] 1-b 2-d 3-a 4-c Question 3 Carol has 18 fruits in a basket, 3 of them are apples, x of them are pineapples and the rest are oranges. An expression in terms of x for the number of oranges in the basket is... [1] 18 − 3x [2] 18 − 3 + x [3] 15 − x [4] 3x − 18 BNU1501/Ass1/2022 Question 4 Match the terms in column B with a statement in column A A B 1. In equation 7x + 2y − 4 = 45,4 is the a. Base 2. The number in front of a variable b. Product 3. When 2 numbers are multiplied the answer is the c. Coefficient 4. In equation 53 = 125,5 is the d.
