Question

Pam likes to practice dancing while preparing for a math tournament. She spends 80 minutes every day practicing dance and math. To help her concentrate better on math, she spends 20 minutes more dancing than doing math.

Part A: Write a pair of linear equations to show the relationship between the number of minutes Pam practices math every day (x) and the number of minutes she practices dances every day (y). (5 points)

Part B: How much time does Pam spend on practicing math every day? (3 points)

Part C: Is it possible for Pam to have spent 60 minutes practicing dance every day? Expla

Answer 1

^^Explain your reasoning

Answer 2

Part A) I think could be
x+y=80
y=x+20

Answer 3

Solving this system of equations you can figure out the number of minutes she spends on math and dancing

Answer 4

r u sure on part a bc i cant get it wrong

Answer 5

@Kainui

Answer 6

The first equation is right because the number of math and dancing = 80

Answer 7

Better have another opinion

Answer 8

ok do u know someone we can tag?

Answer 12

can u help plz!! @ILUVSOCCER

Answer 13

I'll try.

Answer 14

Solve the system you have been given by the previous helper and see if the answers work in the problem description.

Answer 15

ive tried but could u help ?

Answer 16

is this right so far?

Answer 17

Part A: x+y=80
y=x+20

Part B: Pam spends 20 practicing math everyday
The reason why is because if we divided 80/2 it would be 40 but add 20 on dance and subtract 20 on math so dance would have 60 minutes and math would have 20 minutes.

Answer 18

@ILUVSOCCER and @Mertsj

Answer 19

Replace y in this equation: x+y=80 with y = x+20

Answer 20

Now you have: x + x+20 =80
Solve that equation.

Answer 21

thts not what im supposed to do i need x and y

Answer 22

Solve for x and replace angain in any equation to have the value of y

Answer 23

You have the equation x + x+20=80.
If you solve that equation you will have x

Answer 24

i finished tht one could u help on another?

Answer 25

.Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the solutions of the equation 8x = 2x + 2. (4 points)

Part B: Make tables to find the solution to 8x = 2x + 2. Take the integer values of x between −3 and 3. (4 points)

Part C: How can you solve the equation 8x = 2x + 2 graphically? (2 points

Answer 26

Part A: To find the intersection points of two equation you have to match both equations. So that why 8x=2x+2 is the solution for 8x=2x+2

Answer 27

thx do u know part b and c?

Answer 29

I'm not so sure in part be because if you solve for x you got 1/3

Answer 30

@ILUVSOCCER would u know?

Answer 32

What is the question? I mean she spends 60 mins doing math because is 80 is the total of dance and math and 20 is of dance then math is 60

Answer 33

no i wrote the 2nd one is what we are on

Answer 34

do u see it @study312

Answer 35

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the solutions of the equation 8x = 2x + 2. (4 points)

Part B: Make tables to find the solution to 8x = 2x + 2. Take the integer values of x between −3 and 3. (4 points)

Part C: How can you solve the equation 8x = 2x + 2 graphically? (2 points)

Answer 36

@jhonyy9

Answer 37

idk how to do that one

Answer 38

how about this one?

Answer 39

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:

y > 2x + 3
y is less than negative 3 over 2 times x minus 4

Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)

Part B: Is the point (−4, 6) included in the solution area for the system? Justify your answer mathematically. (4 points)
