Answer:
Yes
Step-by-step explanation:
For the first equation all we need to do is distribute 6 to 3x and 5y. 6*3x = 18x and 6*5y = 30y. For the first equation, it will be: 18x + 30y.
The next equation seems hard but it's simple. First you can easily add, 4x and 6x. That will equal 10x. Then from there distribute 2 to 4x and 2y, so do the same thing as before. 2*4x = 8x and 2*2y = 4y. So now our equation looks like this: 10x + 15y + 8x + 4y + 11y. Now all you need to do is add the x's together and the y's together. 10x + 8x = 18x and 15y + 4y + 11y = 30y. Now we have 18x + 30y. Looks the same, and that is true.
Both equations equal 18x + 30y, so therefore the answer is yes or true.

A building has three elevators. Each elevator is out of order 30% of the time.
The following set of random numbers represents 20 simulations of the
elevators, with 0, 1, and 2 representing a broken elevator and 3, 4, 5, 6, 7, 8,
and 9 representing a working elevator. In how many of the simulations were
all three elevators working?
931
188 763 841 559 144 652 277
653 673
404 396 011 843 599 797 414 761 273 844
Answer:
the answer is 9.
Step-by-step explanation:
The total stimulations in which all three elevators are working is 12(option d) by the concept of data representation.
What is data representation?Data Representation: A method for analyzing numerical data is data representation. Data representation is used to create a diagram that shows the connections between facts, ideas, information, and concepts. It is a fundamental learning technique that is clear-cut and uncomplicated. The data type in a particular domain is always what determines it. There are many various styles and sizes of graphical representations.
According to the given data:
A building has 3 elevators.
The following set of random numbers represents 20 stimulations of the elevators, with 0, 1 representing the broken elevator and 2,3,4,5,6,7,8and 9 representing a working elevator.
Stimulation data:
931 188 763 841 559 144 652 277 653 673 404 396 011 843 599 797 414 761 273 844
Now, as we observe from the given data, the stimulation in which all three elevators are working are-
763,559,652,277,653,673,396,843,599,797,273,844a total of 12 stimulations.
Thus, the total stimulations in which all three elevators are working is 12
Hence, option d is correct.

19. A cross section of a water trough is in the shape of trapezoid with bases measuring 4 m and 12 m. what is the length of the
median of the trapezoid?
4
B. 6
C.8
D. 10
Given:
The bases of trapezoid measuring 4 m and 12 m.
To find:
The median of the trapezoid.
Solution:
The median of the trapezoid is the average of its bases.
[tex]\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}[/tex]
The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:
[tex]\text{Median}=\dfrac{4+12}{2}[/tex]
[tex]\text{Median}=\dfrac{16}{2}[/tex]
[tex]\text{Median}=8[/tex]
Therefore, the correct option is C.

Stephanie spent $16 on product and supplies for a lemonade stand. She charged $2 for a cup of lemonade. The graph below can be used to represent Stephanie's profit, y, after selling x number of cups of lemonade.
Answer:
A. The y-intercept represents the amount of money Stephanie has. She started at -16 because she spent $16.
B. The x-intercept is the amount of cups of lemonade she sold. On the graph, it shows that after 8 cups, she made 16 dollars back. She didn't make any profit sense she started at -16.
C. The slope represents how much she made after so many cups of lemonade were sold. It was after 8 cups of lemonade were sold that she started making a profit.

m = 2
I hope this helps, have a good day!( Also m stands for slope if you didn't know)
Answer:
Hi, there your slope will be 2
Step-by-step explanation:
In order to find the slope use the slope formula
Here's the slope formula
[tex]\frac{y2-y1}{x2-x1}[/tex]
Here we will plug the coordinates into the formula:
[tex]\frac{3-(-3)}{1-(-2)}[/tex]=[tex]\frac{-6}{-3}[/tex]=2
Your slope will be 2
Hope this helps :)

Two dice are rolled. What is the probability of getting doubles?
Answer:
the probability of getting doubles is 1 / 6
I hope this may be helpful
Answer:
it is 1/36
Step-by-step explanation:
if you want to get doubles, you have a chance of 1 out of 6 on each die. All you have to do from here is multiply them
1/6*1/6=1/36

Answer:
c. 492 cubic centimetres
Step-by-step explanation:
the equation for the volume of a rectangular prism is
V = Length × Width × Height
we also have to take into account that there are 2 rectangular prisms in that picture so we have to add the volumes of both of them.
for the one on the bottom, the volume would be
V = 9 × 6 × 8
V = 432 cubic centimetres
now we'll do the one on the top
V = 3 × 5 × 4
V = 60 cubic centimetres
now we'll add up both volumes to get a total amount.
432 + 60 = 492 cubic centimetres

how much do they make in a-
week_
month_
year_
Answer:
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48
Step-by-step explanation:
Custodian at Movie Theater
pay:$9.95
per hours:
15.25 hours per week
How much do they make in
1) a- week
1 week = 15.25 hours
Hence,
1 hour = $9.95
15.25 hours = x
Cross Multiply
x = 15.25 × $9.95
x = $151.7375
Approximately = $151.74
2) A month
There are 4 weeks in a month
1 week = $151.74
4 weeks = x
Cross Multiply
x = 4 × $151.74
x = $606.96
3) A year
There are 52 weeks in a year
Hence,
1 week = $151.74
52 weeks = x
Cross Multiply
x = 52 × $151.74
x = $7890.48
Therefore, they made in :
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48

Answer:
Step-by-step explanation:
b/c it's the complement of 47 we know it's 180-47 = x
or
x = 133°
Answer:
x = 133 degrees
Step-by-step explanation:
The 47 degrees is a corresponding angle with the angle on the right of x. Meaning that angle is also 47 degrees. After figuring that out, all you have to do is do subtraction (180-47=133) to get your answer.

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon
Answer:
1/8 cups per teaspoon
Step-by-step explanation:
5/8 cup sugar per 5 teaspoons of vanilla
(5/8 ) divide in 5 will give us how much per 1 teaspoon
(5/8)/5 = (5/8) * (1/5) = 5*1/ 8*5 = 1/8
