If 40% is equal to the fraction x/30, what is the value of x?
A. 0.4
B. 15
C. 1,200
D. 12 correct answers Change 40% to a decimal and write an equation to solve for x.
0.4 = x/30
Multiply both sides by 30. You are "undoing" the division.

If 40% is equal to the fraction x/30, what is the value of x?
A. 0.4
B. 15
C. 1,200
D. 12 correct answers Change 40% to a decimal and write an equation to solve for x.
0.4 = x/30

Which of the following is the smallest prime number greater than 200?
A. 201.
B. 205.
C. 211.
D. 214. correct answers 1. A prime number is a number larger than 1 that has only itself and 1 as
factors. (It can be evenly divided ony by itself and by 1.) 201 is divisible by 3; 205 is divisible by
5; 211, however, is a prime number.
The expression "5 factorial" equals
A. 125.
B. 120.
C. 25.
D. 10. correct answers . The product of all integers from 1 to x is called the x factorial. The
product of all numbers from 1 to 5 is 5 factorial. Thus
(5)(4)(3)(2)(1) = 20 (3)(2)(1)
= 60 (2)(1)
= 120 (1) = 120
The expression 5 factorial" is equal to 120
What is the result of subtracting 3x² - 5x - 1 from 8x² + 2x + 9?
A. 5x² - 3x - 10
B. -5x² - 3x - 10
C. 5x² +7x - 8
D. -5x² - 7x + 8 correct answers To subtract one polynomial from another, you change the signs
of the terms in the subtrahend. First write the example as a subtraction in arithmetic.
(From) 8x² + 2x - 9
(Take) 3x² - 5x - 1
Then change the signs of the terms in the bottom row (the subtrahend) and combine terms that
are alike.
8x² + 2x - 9
, -3x² + 5x + 1
___________
5x² + 7x - 8
What is the meaning of the statement -30 < -5?
A. 30 is greater than 5.
B. 30 is less than minus 5.
C. Negative 30 is less than negative 5.
D. Negative 30 is greater than negative 5. correct answers C. Negative 30 is less than negative
5...In deciding whether a number is greater of less than another, it helps to use a number line.
On the number line above, -5is to the left of 0 and is, therefore, less than 0, but -50 is to the left
of -5. This makes -30 less than -5. The < sign is a symbol of inequality, meaning "less than". The
statement (-30 < -5) means "negative 30 is less than negative 5."
Solve for x: 8x - 2 - 5x = 8.
A. x = 1.3
B. x = 2½
C. x = 3 and 1/3
D. x = -7 correct answers C. x = 3 and 1/3.. To solve for x, combine all similar terms, and set the
equation equal to zero.
(8x - 5x) + (-2 - 8) = 0
Do the operations inside the parenthesis.
3x - 10 = 0
Next, add 10 to each side. You are undoing the subtraction.
3x - 10 + 10 = 0 + 10
3x = 10
Finally, divide each side by 3 to find the value of x> You are undoing the multiplication.
A woman has $500 in a bank account. Every week, she writes out a check for $50. If she doesn't
make any new deposits, what will her bank account hold x weeks from now?
A. $500 + $50x
B. $500 - $50x
C. $500 - x
D. $500 + $50 + x correct answers In x weeks, she will make out checks tor x times $50, or
$50x. To find out how much she still has after writing these checks, she would subtract $50x
from $500. Thus her bank account will hold $500 - $50x
When the temperature is 20ºC, what is it the Fahrenheit (F) scale? (Use the following formula).
