a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.
b) The correct expression is given as follows: -8.6b + 28.
How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.
Then, to simplify the expression, we combine the like terms, as follows:
b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

An engineer created a scale drawing of a building using a scale in which 0.5 inch represents 5 feet. The length of the actual building is 250 feet.
Answer: 50 inches would represent the scale drawing as 250 feet
Step-by-step explanation:
im not exactly sure what your asking but there brainliest if im right?
Answer:
The length of the building in the scale drawing is 31. 25 Inches
Step-by-step explanation:
Scale drawing was used0. 25 inches represents 2 feetThe length of the building is 250 feetThen,
If 0. 25 inches = 2 feet
Then x inches = 250 feet
cross multiply
x × 2 = 0. 25 × 2500
Multiply through, we then have
2x = 62. 5
Make 'x' the subject by dividing both sides by 2
2x/2 = 62. 5/ 2
x = 31. 25 Inches

Answer: the rate of change is 1/2
Step-by-step explanation:
The formula for slope is y2 - y1/ x2 - x1
I picked points (2,2) (x1 & y1) and (6,4) (x2 & y2)
4 - 2 = 2
6 - 2 = 4
2/4 is the rate of change, and 1/2 is 2/4 simplified

Shelly’s Boutique had a Labor Day sale featuring 25% off any item. Tammy wanted to buy a blouse that originally sold for $21.99. To the nearest cent, how much will it cost her before tax to buy the blouse during the sale?
21.99 * .25 = 5.4975
21.99 - 5.4975 =
16.4925
answer : $16.49
Answer:
$16.49
Step-by-step explanation:
21.99 x .75 = 16.4925
Rounded to the nearest cent is 16.49
If we are taking off 25%, that means that we are leaving on 75% or .75

At track practice, Alexia ran 5 attempts of the 100-meter dash. All of her times were different values between 11 and 13 seconds, except for an attempt when she tripped and finished in 24 seconds.
Alexia's coach said they would remove the 24 result from the set of these practice times.
How will removing this time affect the mean and median?
(Choice A)
A
Both the mean and median will decrease, but the mean will decrease by more than the median.
(Choice B)
B
Both the mean and median will decrease, but the median will decrease by more than the mean.
(Choice C)
C
Both the mean and median will increase, but the mean will increase by more than the median.
(Choice D)
D
Both the mean and median will increase, but the median will increase by more than the mean.
Answer:
A is correct
Step-by-step explanation:
khan
Removing this time affects the mean and the median will decrease but the median will decrease by more than the mean.
Option B is the correct answer.
What is median?It is the middles value of the given set of numbers after arranging the given set of numbers in an order.
We have,
The value 24 is an outlier, and its removal will have a greater effect on the mean than on the median.
Since all of Alexia's other times are between 11 and 13 seconds, removing the 24 will bring the mean closer to the values between 11 and 13.
However, the median, which is the middle value of the ordered set, will not change as much, since it is not affected by extreme values like the outlier.
Therefore,
Both the mean and median will decrease, but the median will decrease by more than the mean.

f(x)=1-2x
a. f(-2)
b. f(0)
c. f(2)
Answer: {5, 1, 3}

Answer: 1/2, 0.51, 11/20
Step-by-step explanation:
Use 100 as a common denominator so you can compare all the numbers in like terms:
1/2 = 50/100
0.51 = 51/100
11/20 = 55/100
Answer:
[tex]\frac{1}{2} 0.51, \frac{11}{20}[/tex]
Step-by-step explanation:
First, you want to change the decimal into a fraction. 0.51= [tex]\frac{51}{100}[/tex]
Then, find the common denominator. In my example, I used 100. Find the equivalent fraction for the fractions with 100 as their denominator
[tex]\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}[/tex]
Next, line them up in order of their numerators
[tex]\frac{50}{100} \frac{51}{100} \frac{55}{100}[/tex]
Finally, match the new fraction with their reduced fraction or decimal:
[tex]\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}[/tex]

Which of the following elevations is less than negative -5 feet from sea level?
A)negative -10 feet
B)negative-3 feet
C) positive 2
D) positive 5 feet
Solution:
An elevation of -10 ft would be less than -5 ft from sea level.
(NOTE) When it comes to negative integers on a number line, just keep in mind that the closer to 0 the negative integer is, the greater in value it becomes. However, the further away from the zero mark the integer is, the value decreases/is a smaller number.
This being said, lets look at the given options.
A) -10 feet ← Notice when you place -10 on the number line, the point is far to the left of the zero mark, as well as -5. This being said, this most likely means that this is a lesser elevation level than that of -5 feet from sea level.B) -3 feet ← Notice when you place -3 on the number line, the point is also to the left of the zero mark, however it is ahead of -5. This being said, this elevation is not lesser than -5 feet from sea level, and hence not the correct choice.C) 2 feet ← Notice when you place 2 on the number line, the point is just to the right of the zero mark and is definitely ahead of -5 feet. This means that this elevation is not lesser than -5 feet from sea level, and hence is not the correct choice.D) 5 feet ← Notice that when you place 5 on the number line, the point is to the right of the zero mark and is definitely also ahead of -5 feet. This being said, this means that this elevation is not lesser than -5 feet from sea level, and hence is not the correct choice.Hence, in conclusion to all of this, our correct choice would be A) -10 feet, considering it is the only elevation that is less than -5 feet from sea level.

The answer you are looking for is 33807
Answer:
y:=33806.526
y=33807.(Rounded off)
Step-by-step explanation:
y=(34567(1−0.022))
Solve for y
y=50016903263=33806500263=33806.526
Steps for Solving Linear Equation
y=(34567(1−0.022))
Subtract 0.022 from 1 to get 0.978.
y=(34567×0.978)1
Multiply 34567 and 0.978 to get 33806.526.
y=33806.5261
Calculate 33806.526 to the power of 1 and get 33806.526.
y=33806.526
Assign y
y:=33806.526
y=33807.
oints (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park:
A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2.
Which statement best describes the relationship between the positions of the two players? (4 points)
a
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
b
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
c
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
d
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
Answer: B
Explanation:
Correct way to write down co-ordinates: x,y
Dog 1's position: (-6,3)
Dog 2's position: (-6,-3)
Similarity: Both co-ordinates have -6 on the X axis (left to right line)
Difference: Dog 2's Y co-ordinate is NEGATIVE 3 while dog 1's Y co-ordinate is POSITIVE 3
The position is going to be reflected across the X axis because their X co-ordinates are the same, so dog 1 will be on the positive section for the Y axis (line that goes up and down) while Dog 2 will be on the negative section of the Y axis since it has negative 3 as its Y co-ordinate.

Tom has 2 boards that are the same length as Bill's. He says that he found the total length of the boards by adding 28 twelfths and 23 twelfths. Does his method work? Explain.
Answer:This method does not work
Step-by-step explanation:
Since the 2 boards have the same length, the addition of the 2 boards should be the same.
Since 28 does not equal to 23, the method will not work.
