Describe and correct the error in finding the solution.
-4.2x=21
-4.2x/4.2=21/4.2 x=5
Answer:
The error is that the person divided both sides by positive 4.2 rather than negative 4.2. Here's how to correct it:
-4.2x ÷ -4.2 = x, 21 ÷ -4.2 = -5So, x = -5.I hope this helps!

The average weight of the top 5 fish at a fishing tournament was 13.3 pounds. Some of the
weights of the fish are shown in the table.
Answer:
15.4 lbs
Step-by-step explanation:
Since the average of the top five is 13.3 this says that:
total weight of all the fish / 5 = 13.3 lbs
Therefore, the total weight of all five fish is equal to:
13.3 * 5 = 66.5
With this number, I subtracted all the other weights and found that the missing weight was:
15.4lbs.
Therefore, Wayne S. had the biggest fish weighing 15.4lbs
Answer:
15.4
Step-by-step explanation:
(14.2 + 13.4 + 12.1 + 11.4 + X) / 5 = 13.3
(51.1 + X) / 5 = 13.3
Cross:
51.1 + X = 66.5
then X = 66.5 - 51.1
= 15.4

Crystal baked 54 muffins for her family and friends. Her friends take 1/6 of the muffins. How many muffins does she have left? Of the muffins that she has left, her family took 2/5 of them. How many muffins did her family take? After her friends and family have taken their muffins, Crystal eats 1/3 of what is left. How many muffins did Crystal eat?
Answer:
she has 45 muffins left
her family took 18 muffins
crystal ate 9 muffins
Step-by-step explanation:
54 × 1/6 = 9
54 - 9 = 45
45 x 2/5 = 18
45 - 18 = 27
27 x 1/3 = 9

Sally and Anne went to the movies. They each purchased a drink. They also bought one popcorn and one veggie cup to share. Each woman's total is modeled with this expression: 9+1.34+1/2(3.50+1.74) How would you simplify the expression? Explain your steps.
Answer:
12.91
Step-by-step explanation:
We are told that Each woman's total is modeled with this expression:
9 + 1.34 + 1/2(3.50 + 1.74)
To solve this we will use the BODMAS acronym.
So the first operation will be to solve what's in the bracket to give;
9 + 1.34 + 1/2(5.14)
Let's now carryout the multiplication of the bracket to give;
9 + 1.34 + 2.57
Using the addition operation now gives us: 12.91
Answer: First, add the decimals in the parentheses. Next, multiply that number by 0.5. Finally, add all the decimal numbers.
A bookstore marks up the price of a book by 40% of the cost from the publisher. Therefore, the bookstore's price to the student, P(x) (in $) after a 7.5% sales tax, is given by P(x) = 1.075(x + 0.40x), where x is the cost of the book from the publisher. Evaluate P(60) and interpret the meaning in the context of this problem
Answer:
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
Step-by-step explanation:
Solution:
The cost of book from publisher = 40%
Sales tax = 7.5%
Price of books to the student = p(x) = 1.075x + 0.40x
Where, x is cost of book.
P (60) =?
We know that,
P(x) = 1.075 + 0.40
= 1.475%
=148
Given, Cost of book, x = 60
P (60) = 148 – 60
= 88
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
