Step-by-step explanation:
The model represents an equation.
What value of x makes the equation true?
The original quantity is 20 and the new quantity is 15. Adam incorrectly says the percent decrease is about 14.29%. What is the correct percent decrease? What error did Adam likely make when finding the percent decrease? The correct percent decrease is 25 25%. What error did Adam likely make? A. divided the difference of the two quantities by the sum of the two quantities. B. divided the difference of the two quantities by the product of the two quantities. C. divided the difference of the two quantities by the new quantity. D. divided the new quantity by the original quantity.
Answer: A. divided the difference of the two quantities by the sum of the two quantities.
===================================================
Explanation:
The difference of the quantities is 20-15 = 5
The sum of the quantities is 20+15 = 35
Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429
That converts to 14.29%
This is likely the path Adam took. This path is incorrect. The correct steps are shown below
---------------------
Difference = 20-15 = 5
Divide the difference over the original quantity
5/20 = 1/4 = 0.25 = 25%
We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)
----------------------
Here's another way to approach the problem
A = old value = 20
B = new value = 15
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-20)/20 ] * 100%
C = (-5/20)*100%
C = -0.25*100%
C = -25%
The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.

Solve for M
-7+4m+10=15-2m
Answer:
m=2
Explanation:
see .pdf file
Answer:
m=2
Step-by-step explanation:
-7+4m+10=15-2m
We move all terms to the left:
-7+4m+10-(15-2m)=0
We add all the numbers together, and all the variables
4m-(-2m+15)-7+10=0
We add all the numbers together, and all the variables
4m-(-2m+15)+3=0
We get rid of parentheses
4m+2m-15+3=0
We add all the numbers together, and all the variables
6m-12=0
We move all terms containing m to the left, all other terms to the right
6m=12
m=12/6
m=2

Write 0.45% as a fraction in simplest form.
Answer:
9/20
Step-by-step explanation:
Mike hiked to a lake in 5.5 hours at an average rate of 2 1/5 miles per hour. Pedro hiked the same distance at a rate of 2 3/5 miles per hour. How long did it take for Pedro to reach the lake? Round to the hundredths place.
We first need to find the distance.
The information about Mike will provide the distance we need to answer the question about Pedro.
We will use D = rt
Mike:
(6.5)((17/5) = D
22.1 miles = D
Pedro:
D = rt
22.1 = (19/5)t
We need to find t.
22.1 ÷ 3.8 = t
5.8157894737 = t
We now round off as instructed.
5.82 = t
It took Pedro 5.82 hours to reach the lake.

Determine if the given value makes the equation true or false. For x3 – 8 = 15, if x = 69
Answer:
(69)(3)−8 = 15
199≠15
False
Step-by-step explanation:
hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.
Answer:
False
Step-by-step explanation:
69 * 3 =207
207 - 8 = 199
x3 - 8 = 199 for x = 69

PLZZ HURRY!! What numbers are a distance of 1/2 unit from 3/5 on a number line? Select the locations on the number line to plot the points.
Answer:
Step-by-step explanation:
The numbers that are a distance of 1/2 unit from 3/5 on a number line are the numbers that are 1/2 units to the right and to the left of 3/5 on the number line.
The numbers are given by 3/5 - 1/2 and 3/5 + 1/2.
The numbers are 1/10 and 1 1/10
The required numbers are 0.1 and 1.1 are a distance of 1/2 unit from 3/5 on a number line.
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
We have been given that number line, the numbers that are 1/2 units away from the number 3/5 are the numbers that are 1/2 units to its right and left.
The numbers are given by 3/5 - 1/2 and 3/5 + 1/2.
So the required numbers would be:
⇒ 3/5 - 1/2 = 1/10 = 0.1
⇒ 3/5 + 1/2 = 11/10 = 1.1
Therefore, the required numbers are 0.1 and 1.1 are a distance of 1/2 unit from 3/5 on a number line.

x+3y=-2 and 5x-3y=26 in (x,y) form pls!!
x + 3y = -2
=> x = -2-3y ----iAlso 5x -3y = 26
=> 5 (-2-3y) -3y =26
=> -10 -15y -3y =26
=> -18y = 36
=> y = -2Putting y = -2 in equation i we get,
x= -2 -3(-2)
=> x = -2 +6
=> x = 4Thus The solution is (4, -2)Answer:
(4, -2)
Step-by-step explanation:
Please be sure to share ALL of the instructions. Here you meant "Solve the following set of simultaneous equations and present your solution in (x, y) form."
Note that the first equation features +3y and that the second features 5x - 3y = 26. Simply adding like terms results in our having eliminated the variable y:
6x = 24
Then x = 24/6 = 4
The x coordinate of the solution is 4; Substituting 4 for y in the first equation results in
4 + 3y = -2
which simplifies to 3y = -6. Thus, y = -2, and the solution is
(4, -2)

Aaliyah measured a line to be 8.7 inches long. If the actual length of the line is 8.3 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
The Percent Error of the measurement is 4.59%.
What is Percent Error?The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
Given:
Aaliyah measured a line to be 8.7 inches long.
If the actual length of the line is 8.3 inches.
So, the Percent Error
= | (approx - exact) ÷ approx | x 100
= 8.7 - 8.3)/ 8.7 x 100
= 0.4/ 8.7 x 100
= 4.59
