Priya is simplifying the expression $$ Her work is shown to the left. Priya's work is incorrect. Explain the error she made
Answers
Step-by-step explanation:
P.S - The exact question is -
Given - Priya is simplifying the expression -2(4 - 2x) - 3 - 2x Her work is shown to the left.
To find - Priya's work is incorrect. Explain the error she made.
Proof -
Priya simplified the problem as follows :
-2( 4 - 2x ) - 3 - 2x
-8 - 2x - 3 - 2x
-11 - 4x
But the simplification has to be like
-2( 4 - 2x ) - 3 - 2x
⇒-2(4) - 2(-2x) - 3 - 2x
⇒-8 + 4x - 3 - 2x
⇒-8 - 3 + 4x - 2x
⇒-11 + 2x
So, Priya made an error in the second line.
In the second line it has to be -8 + 4x - 3 - 2x but Priya has written -8 - 2x - 3 - 2x.

Shanti is making a patchwork quilt. Each piece of fabric has a black star on it. She uses the grid shown to plan the locations of the different fabric squares.
a. What transformation maps square 1 onto square 2?
b. What transformation maps square 2 onto square 3?
c. What transformation maps square 1 onto square 5?
Answers
Answer:
A) Translation
B) Reflection
C) Rotation
Step-by-step explanation:
The transformation types in mathematics are;
Reflection, translation, rotation and dilation.
We can see that the squares are all the same size, it's just the position of the stars that will aid us in knowing the specific transformation.
A) We can see that square 2 is the exact same thing as square 1. Just that it was shifted to the right of square 1. Thus, it was translated and the transformation is translation.
B) We can see that the star in square 3 is the exact mirror copy and location from square 2. Thus, this is a reflection.
C) We can see that the position of the star in square 5 is top while that in square 1 is at the left corner. This can only be achieved by rotation.

The ratio of the length to the width to the height of an open rectangular tank is 10: 5: 8. The height is 18 feet longer than the width. What is the volume of the tank
Answers
Answer:
hi
Step-by-step explanation:
how are you
Answer: A: L: W: H = 10: 5: 8
Step-by-step explanation: The height of the tank is 18 feet longer than the width
H = 8 parts, W = 5 parts => 8 – 5 parts = 18 feet i.e. 3 parts = 18, 1 part = 6 feet
Hence, L = 10 * 6 = 60 feet
W = 5 * 6 = 30 feet
H = 8 * 6 = 48 feet
Volume = 60 * 30 * 48 = 86400 ft³
Surface Area = 2 * (30 * 60 + 48 * 60 + 30 * 48) =12240 ft²

Solve for x . x/2 + 1.1= -2.1
Answers
Answer: x = 1.6
Step-by-step explanation:
Start by Identifying what you need to keep, in this case that would be X. In order to solve for x, you would need to get rid of any co-efficients. (example: +1.1) To get rid of them, you have to do the opposite action of what it's doing to the equation. (subtraction)
1.1- (-2.1) = 3.2 (if you subtract a negative, it turns positive/ you add) leaving you with x/2 = 3.2.
Now that we have our coefficient out the way, we have to get rid of the division so we can only solve for x. We do that by dividing the remainder of the equation by 2
3.2/2 = 1.6
Leaving us with the answer, x = 1.6

The U.S. Department of Labor reports that the average prices for a dozen eggs in the month of May for the past 11 years are as follows: $1.19, $1.21, $1.50, $1.93, $1.50, $1.52, $1.69, $1.69, $1.87, $2.00, $1.96 Round to the nearest hundredth (cent) if necessary. The mean price of eggs over this 11-year period is The median price of eggs over this 11 -year period is
Answers
Answer:
Mean price of eggs = $1.64
Median price of eggs = $1.69
Step-by-step explanation:
Mean is the average of the given data
Mean = sum of data/sample size
Sum of data = 1.19+1.21+1.50+1.93+1.50+1.52+1.69+1.69+1.87+2.00+1.96
Sum of data = $18.06
Sample size = 11
Mean price of eggs =18.06/11
Mean price of eggs = $1.64
Hence the mean price of eggs over this 11-year period is $1.64
Median is the price in the middle after rearrangement
Rearranging the data
1.19, 1.21, 1.50, 1.50, 1.52,) 1.69, (1.69, 1.87, 1.93, 1.96, 2.00
Since 1.69 falls in the middle after rearranging;
Hence the median price of eggs over this 11 -year period is $1.69
