Hey can someone help I am stumped.
Add the two equations together to get:
4y = -4
Solve for y by dividing both sides by 4:
Y = -1
Now you have a value for y, solve for x in the first equation:
2x + 3(-1) = 7
2x -3 = 7
Add 3 to both sides:
2x = 10
Divide both sides by 2:
X = 5
Answer: x = 5 and y = -1

Westin performed an experiment in which he randomly pulled a marble from a bag, recorded its color, put it back, and then repeated. He did this 36 times, and 9 of those times he pulled a purple marble.
Which bags of marbles are good models for this experiment?
Select two that apply.
A ) 4 purple, 5 blue, 2 green, 1 red
B ) 4 purple, 5 blue, 2 green, 1 red
C ) 9 purple, 9 red, 9 green
D ) 9 purple, 9 red, 9 green
E ) 1 purple, 1 blue, 1 green, 1 red
F ) 1 purple, 1 blue, 1 green, 1 red
G ) 4 purple, 4 blue, 4 yellow, 4 orange
Answer:
Step-by-step explanation:
Based on the experiment, 9 times he pulled a purple marble out of the 36 trials.
That means he has a 1/4 probability of pulling a purple marble
This means that the purple marble ideally makes up one-quarter of the total marble in the bag.
Choice G and F satisfy the condition as stated above.
Hope that helps!

The variables x and y have a proportional relationship, and y= 5/6 which equation represents this relationship? x= 3/4. Which equation represents this relationship?
Answer:
(d) y= (1 1/9)x
Step-by-step explanation:
A proportional relation is described by the equation ...
y = kx
Dividing by x shows how to find the value of k:
k = y/x
For the given values of y and x, the value of k is found to be ...
k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9
The relationship is represented by the equation ...
y = (1 1/9)

{30 POINTS!} HELP! Two communications companies offer calling plans. With Company X, it costs 35¢ to connect and then 5¢ for each minute. With Company Y, it costs 20¢ to connect and then 4¢ for each minute. Write and simplify an expression that represents how much more Company X charges, in cents, for n minutes
(35+5n)−(20+4n)
Answer:
(20 + n)¢
Step-by-step explanation:
With Company X, it costs 35¢ to connect and then 5¢ for each minute.
So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢
Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.
So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.
Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)
On average, a largemouth bass weighs about 12 pounds. Two fishermen weighed the largemouth bass they both caught and found their catch weighed 82 pounds. What is the greatest number of largemouth bass caught that are average weight?
82÷12=6.833333333333
The greatest number of largemouth bass caught is 6.
What is Average?In mathematics, the central value of a set of data is expressed as the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data.
As per the given data:
Average weight of largemouth bass = 12 pounds
Weight of all largemouth bass caught = 82 pounds
n = number of largemouth bass
Average = (Sum of all observations / Number of observations)
Average weight = (Average weight of largemouth bass / n)
12 = (82 / n)
n = (82 / 12)
n = 6 {considering only integer value}
Hence, the greatest number of largemouth bass caught is 6.

A keyboarding instructor at a community college collected data comparing a student's age and their typing speed. The equation for the line of best fit is given at y = -1.4x + 117.8, where x is the "age in years" and y is the "typing speed."
If you are 25 years of age. what is your typing speed?
A-153 words per minute
B-83 words per minute
C-63 words per minute
D-102 words per minute
HELP THIS IS TIMED!!!!
in answer:
The answer would be B
Step-by-step explanation:
Going off the y=mx+b equation, you would multiply -1.4 by 25 then add 117.8 to that result. The total of your equation would result in 82.8 words per minute.
