Step-by-step explanation:
1. Let's review the information provided to us for solving the question:
Which of the following is the approximate square root of 24, rounded to the nearest whole number?
We are asked to find out the square root of 24 and if the number has a lot of decimal places, round it to the closest whole number.
√24 = √6 * 4 (Simplifying)
√6 * 4 = 2 √6
2 √6 = 2 * 2.44948974 = 4.89897948
<u>Rounding to the nearest whole number the answer is 5.</u>
Answer:176 psychology textbooks and 98 Biology textbooks were sold.
Step-by-step explanation:
Let x represent the number of psychology textbooks that were sold.
Let y represent the number of biology textbooks that were sold.
textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that
x + y = 274 - - - - - - - - - - -1
The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that
x = y + 78
Substituting x = y + 78 into equation 1, it becomes
y + 78 + y = 274
2y = 274 - 78
2y = 196
y = 98
x = y + 78 = 98 + 78
x = 176
