Answer 18

Auditions for a new, upcoming band in Chicago were held with 124 men and women trying out for the lead singer position. If twice the number of men less three times the number of women is equal to 28, how many women auditioned?

40

44

70

80

Answer 19

We will use system of equations here

Answer 20

M = number of men
W = number of women
Use a system of equations:

M + W = 124
2M - 3W = 28

change M + W = 124
to: M = 124 - W

plug that into 2M - 3W = 28 and solve for W

2(124 - W) - 3W = 28
248 - 2W - 3W = 28
-5W = -220
W = 44

44 women auditioned

Answer 22

Thank you ok next are 1 out of the 2 written answers

Answer 23

For the following system of equations, write your own real world scenario that describes what is happening. Use complete sentences and correct grammar in your scenario.

Part 2:
Solve the system and explain what the results mean according to your scenario.

2x + y = 9
3x + 4y = 26

Answer 24

Part 1:
You are buying potatoes and meat. If you buy 2 pounds of potatoes and one pound of meat it will cost you $10, if you buy 3 lbs of potatoes and 4 lbs of meat you will pay $25. How much do potatoes and meat cost?

Part 2: Let x be the cost of potatoes and y the cost of meat (in dollars per pound). Then 2 lbs of potatoes and 1 lb of meat will cost 2x+y=10 and 3 lbs of potatoes and 4 lbs of meat will cost 3x+4y=25.
Solving the equations: from the first equation we get y=10-2x. Plugging in the second gives
3x+4(10-2x) = 25.
Getting rid of parentheses we get
-5x + 40 = 25 and therefore 5x=15, giving us x=3. Therefore y=10-2*3=4. Potatoes cost $3 per pound and meat $4.

Answer 25

Ok perfect @UditKulka ready for the next one?

Answer 26

yes

Answer 27

] You graph a system of equations and the two lines overlap, or lie right on top of one another. Explain what this tells you about the:

solution to the system
the two equations
the result if the system was solved algebraically

Answer 28

if they intercept at one point, the solution is the intersecting point
if they are parallel , and do not intercept, there is no solution
if they are parallel and they are same line, there is infinite solution



where the lines intersect, the equations are equal. (If they were simultaneous equations, these would be the solutions)

where the lines lie on top of each other, one equation can be rearranged to be the other equation precisely. this means when solving, you would get y=y and x=x. there are infinite solutions in this case (every point along the line would be a solution).

(as an addition: where the lines dont cross at all, there is no real solution to the system (e.g. x^2 = x^2 + 5))

Answer 29

@UditKulka I can't use the first one because my teacher would say its against the academic integrity rules to copy Can you please just make one for me
