4. Combine the two equations to eliminate one of the variables, and then solve for the other. (3 points: 1 for eliminating one variable, 1 for the answer, and 1 for showing your work)
Answers
Answer:
Step-by-step explanation:
The solution of the system is:
(x, y) = ( 5, 10)
We have the following system of equations:
12x + 6y = 120
4x + y = 30
Now, We have to solve by the method of elimination, we multiply the second equation by -3, then:
12x + 6y = 120___(1)
-12x - 3y = -90___(2)
Now, We add both the equations:
12x -12x + 6y - 3y = 120 -90
3y = 30
y = 10
We have to find the value of 'x":
4x + y = 340x + 10 = 30
4x = 30 - 10
x = 5
Thus, the solution of the system is:
(x, y) = ( 5, 10)

Is the graph shown at right the graph of -2x + 5y = 20? yes or no? explain your thinking
ILL GIVE YOU BRAINLIST
Answers
Yes
Rewrite the equation in slope intercept form.
First add 2x to both sides:
5y = 2x + 20
Divide both sides by 5
y = (2/5)x + 4
Based on this equation, the y-intercept is 4, which is true for the graph. The slope is 2/5, which is also true for the graph, seeing as how there are points at (-5,2), (0,4), and (5,6). Between each point you go 2 up and 5 to the right.

The water depth of a pond is initially 36 inches and decreases at a rate of 0.2 inches per day through evaporation. Write a linear function that represents the depth of the pond at a given time.
Answers
Answer:
36-0.2d
Step-by-step explanation:
d refers to the number of days
This should work for your question if not I'm very sorry
The required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.
What is the equation?
The equation is the relationship between variables and constants represented as y = ax + b is an example of a polynomial equation.
Here,
The water depth of a pond is initially 36 inches
The water depth of a pond decreases at a rate of 0.2 inches per day through evaporation.
Let the number of the days be x , and the depth left be y
According to the question,
Total depth in x days = 0.2x
Total remaining depth = 36 - 0.2x
or
y = 36 - 0.2x
Thus, the required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.

5B. Using the balanced seesaw shown, find the ratio of lengths a/b in lowest terms.
Answers
Answer:
Lowest terms is 7:6
Step-by-step explanation:
A = 63
B = 54
Ratio is a:b = 63:54
63:54
Reduce 63 to lowest terms to get 7 by dividing 9.
63 ÷ 9 = 7
Reduce 54 to lowest terms to get 6 by dividing 9.
54 ÷ 9 = 6
So the reduced form 63:54 in ratio is 7:6.
7:6
I hope this helped!
Answer:

Step-by-step explanation:
weight * distance = weight * distance,

Describe the shape of the data summarized in the histograms.
Answers
Answers:
5) Roughly symmetrical6) Skewed to the right (aka "right skewed" or "positively skewed")
=======================================================
Explanation:
5) We don't have perfectly symmetrical data, as that would require the left half to be a perfect mirror copy of the right half. However, we have some semblance of symmetry going on. In the middle is 5 which is where the highest bar is, where the mode is located. The mean and median are likely to be around here as well. Then on either side of this highest peak are bars of shorter heights. The heights decrease as we move away from the center in either direction. We can draw an estimated or approximated bell curve (aka normal distribution curve or gaussian curve) to get a fairly good sense of how the data is roughly symmetric. The right-hand portion of this graph is shorter compared to the left side, but I don't think that's enough info to say if we have skewed data or not; so I would stick with "roughly symmetric" here.6) Unlike problem 5, we don't have symmetric data. Instead, we have data that is skewed to the right. The main cluster is grouped or centered on the left side, while we have some outliers to the right side. Draw a curve over each peak of the bars and you'll see that the right tail is pulled longer than the left tail is. We consider this a positively skewed distribution because there are outliers in the positive x direction compared to the main cluster. In contrast, a negatively skewed distribution would have outliers smaller than the main cluster. The mean is larger than the median for a right-skewed distribution. This is due to the mean being pulled on by the outlier, while the median is robust and isn't affected by outliers no matter how distant they are.
