How many rational solutions does the square root of -1 have?

1. One                               3. None

2. Two                               4. Infinitely many 

Since the square roots of negative numbers are complex numbers, not rational, sqrt(-1) has no rational solutions.

Solve:

2x+16=18.

First, subtract both sides:

2x+16=18  ----> 2x=2

Divide by both sides to isolate x:

2x=2 ---> x=1

So, x equals 1.

You have 3 cards labelled A, B, and C. You pick two cards out. What is the probability that Card A is remaining?

1.   1/6                                        3.  2/3

2.   1/3                                        4.  5/6                              

Since there are 2 outcomes of failure (A and B, or A and C) and one outcome of success (B and C), thus your answer is (success/total), the answer is 1/3.

How many solutions does the following equation have?

12x+24=12x+28

1. Infinitely many                 3. Three solutions

2. No solutions                     4. One solution

If we tried to solve for x:

Subtract 12x from both sides:

12x+24=12x+28 ---> 24=28

So: 24=28?

The answer does not make sense, so there are no solutions.

There is a five-digit number 2018X. What is the 𝙨𝙢𝙖𝙡𝙡𝙚𝙨𝙩 value of X so that the number is divisible by 3?

A.      5                                   C.      2

B.      8                                   D.      1

Solution: 2+0+1+8 is 11. To get to the next number that is divisible by 3, which is 12, we have to do 12-11 which is 1. 

So, the smallest value X can be is 1.

Check: 20181/3 = 6787. 20181 is divisible by 3.

A playground has a length that is double that of the width. The perimeter of the playground is 60m. What is its area of the playground?

A. 165m²                                     C. 200m²

B. 290m²                            D. 180m²

We have to use algebra.

Let width=x. Thus, since length is double width, length is 2x. And then, since perimeter is length+length+width+width, our equation is 2x+2x+x+x=60, which simplifies to 6x=60. Therefore, by isolating x, x becomes 10. Then, we can just calculate area by length times width, which is 2x times x. Substitute 10, and it becomes 

2(10) x 10, which becomes 20x10, and thus the area is 200m².
