Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.
Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5
What is the unknown fraction?
Answer: 47/100
Step-by-step explanation: I converted 2/10 to 20/100 and then i subtracted 20 from 67 and got 47 and my answer was 47/100.
Step-by-step explanation:
[tex]0.2 + x = 0.67 \\ x = 0.67 - 0.2 = 0.47 \\ = \frac{47}{100} [/tex]
A builder is buying property where she can build new houses. The line plot shows the sizes of the lots for each house. What is the average size of the lots?
Answer:
Average size of the lots = ⅓ acre
Step-by-step explanation:
The question incomplete without specifying what we are to determine.
Question:A builder is buying property where she can build new houses. The line plot shows the sizes for each house. 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X's. Organize the information in a line plot. What is the average size of the lots? _________ acre
Help anyone?
Solution:
We are asked to organize the information in a line plot. See attachment for the line plot.
Given: 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X'sIn no particular order, the sizes of the lots are:1/6, 1/6, 1/6, 1/6, 1/6, 1/6, 1/3, 1/3, 1/3, 1/2, 1/2, 1/2, 1/2, 1/2 and 1/2 acre.
Let's count the number of lot for each size given.
For 1/6: there are 6 X's on the line plot of 1/6 number of lot for 1/6
= the lot × number of times it occurs
= (1/6) × 6 = 6/6 = 1 acre
For 1/3: there are 3 X's on the line plot of 1/3 number of lot for 1/3 = the lot × number of times it occurs
= (1/3) × 3 = 3/3 = 1 acre
For 1/2: there are 6 X's on the line plot of 1/2 number of lot for 1/2
= the lot × number of times it occurs
= (1/2) × 6 = 6/2= 3 acres
To find average size of the lots, we would sum all lot for each given size then divide by the total number of lots given.Sum of all lot for each given size = 1+1+3
Sum of all lot for each given size = 5
The total number of lots given = 15
Average size of the lots = 5/15 = 1/3
Average size of the lots = ⅓ acre

Answer:
A. 38 degrees
Step-by-step explanation:
That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.

Part A: Identify the Minimum, First Quartile, Median, Third Quartile, and Maximum for the data.
64, 53, 60
60, 56, 58
51, 55, 60
A. Minimum: 51, First Quartile: 55, Median: 58, Third Quartile: 60; Maximum: 64
B. Minimum: 51, First Quartile: 55.5, Median: 59, Third Quartile: 60; Maximum: 64
C. Minimum: 51, First Quartile 54.5, Median: 57, Third Quartile: 60; Maximum: 64
D. Minimum: 51, First Quartile: 54, Median: 58, Third Quartile: 60; Maximum: 64
Answer:
Yes! This is my area!
Step-by-step explanation:
Minimum= 51
Maximum=64
To find the median put the numbers in order
51,53,55,58,60,60,64
no cross off one by one to get the middle number
you end up with 58
first quartile is the upper half so that would be 53
third quartile is the lower half so that wou;d be 60
Hope this helps!
Answer:
D
Step-by-step explanation:
when you put them in numerical order, you have 51, 53, 55, 56, 58, 60, 60, 60, 64
the minimum is the smallest number in the data set. the maximum is the largest number in the data set.
the median is the measure of center, which indicates the middle number in the data set
the first quartile is the center of the bottom set of the data
the third quartile is the center of the upper set of the data
(the upper and lower sets are indicated by which side of the median they are on)
hope this helped :)

The difference of x and y is 14. The value of x is 3 more than twice the value of y. Write two equations and graph to find the value of x.
Answer:
system of equations
Step-by-step explanation:
x-y=14
x = 2y+3
x - y = 14
x -2y = 3
x - y = 14
-x + 2y = -3
y = 11
x = 25

Answer:
422[tex]cm^2[/tex]
Step-by-step explanation:
1. Approach
This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.
2.Find the surface area of the first figure
The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).
(5) * (10) = (50)
(5) * (7) = (35)
(7) * (10) = (70)
Now add thee value together,
(50) + (35) + (70)
= (155)
Double the result,
(155) * (2) = (310)
3. Find the surface area of the other figure
Now repeat the process that was used to find the surface area of the other figure for this figure.
(8) * (4) = (32)
(4) * (3) = (12)
(8) * (3) = (24)
Add the results,
(32) + (12) + (24) = (68)
Double the value,
(68) * (2) = (136)
3. Now subtract the repeated side
Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.
(310) + (136) = (446)
(446) - ((2)*(4)*(3))
= (446) - (24)
= (422)

Cindy is saving for a trip to Hawaii. Each week, she puts aside the same amount of money for her airfare. After 9 weeks of saving, she needs $390 more for her airfare. After 14 weeks, Cindy still needs $240. How much does Cindy put aside each week for her airfare? How much is the airfare to Hawaii?
Answer:
I might be wrong but I did the calculations and my answer is that she put $30 aside each week and the airfare to hawaii is $660
Step-by-step explanation:
This is how I find my answer
first:
14 weeks - 9 weeks = 5 weeks
$390 - $240 = $150
$150/5 = $30 ( that is what she save per week)
then I did
$30 x 140 = 420 + 240 = $660
