Put them in order from least to greatest

25, 26, 31, 32, 39, 57

There is an even amount of data so take the two center points and divide by 2

31 + 32 = 63

6x + y = 15
-7x - 2y = -10

Answers

Answer: x = 4 y=-9

Step-by-step explanation:

Answer:

x = 4

y = -9

Step-by-step explanation:

Isolate a variable from one of the equations ( I chose the first equations cuz it's easy): 6x + y = 15 will be y = 15 - 6x

Substitute the above equation in the place of y in the second equations:

-7x -2(15 - 6x) = -10

-7x -30 + 12x = -10

-30 + 5x = -10

5x = 20

x = 4

To find y-value, substitute the x-value gotten in any equation:

y = 15 - 6(4)

y = 15 - 24

y = -9

Hope this helps!

help me with this question please, explain why u choose that answer and show ur steps

Answers

Let’s condense the original expression and see if that’s one of the answers

-1/2(-3/2 x + 6x + 1) - 3x

First we distribute the -1/2

((-1/2)(-3/2 x) + (-1/2)(6x) + (-1/2)(1)) -3x

3/4x - 3x - 1/2 -3x

Combine like terms

(3/4 x - 3x - 3x) -1/2

-21/4 x - 1/2

We could make this a mixed number

-5 1/4 x - 1/2

(Mixed number: 5 times 4 plus one gets the numerator)

So the answer is D

If there are 120 6th graders and 30% of them are picked to be participate in the school play, how many students are in the play (provide number only) *

Answers

Answer:

36 6th graders are in the play

Step-by-step explanation:

hope this helps

Answer:

36 students

Step-by-step explanation:

Your output value is 120. You represent the unknown value with x.

120 = 100%.

x = 30%.

120=100%(1)

x = 30%(2)

120/x = 100%/30%

x/120 = 30/100        

Therefore, 30% of 120 is 36

Rachel, Kayla, and Francesca raised $35.67 for their basketball team. Rachel and Kayla each raised the same amount, and Francesca raised $10.50 more than each of them.

If x = the amount raised by Kayla, choose the expressions that represent the amount each other player raised. PICTURE ADDED

Answers

Answer: Expression for the amount raised by Rachel = x
Expression for the amount raised by Francesca = x+10.50
Step-by-step explanation:
Let x = the amount raised by Kayla.
Since Rachel and Kayla each raised the same amount.
then, expression for the amount raised by Rachel = x
Francesca raised $10.50 more than each of them.
Then, expression for the amount raised by Francesca = x+10.50

Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday,
Wednesday, and Friday, she runs 4 laps on a running trail and then runs 6 more miles. On Tuesday and
Sunday, she runs 6 laps on the trail and then runs 2 more miles. On Saturday, she just runs laps. How
many laps does Lilliana run on Saturday?

Answers

Answer:

7

Step-by-step explanation:

Let's call x the amount of miles that equal a lap.

So on Monday Wednesday and Friday, she runs 4x + 6 miles.

On Tuesday and Sunday she runs 6x + 2 miles.

And the problem says that she runs the same distance every day, so that means that

4x + 6 = 6x + 2

Now we solve that equation:

4x + 6 = 6x + 2

6 = 6x + 2 - 4x

6 - 2 = 6x - 4x

4 = 2x

x = 2

After that we choose either 4x + 6 or 6x + 2 to calculate the distance she runs on per day by replacing the x with a 2.

4(2) + 6 = 14

6(2) + 2 = 14

Finally we just divide the amount of miles (14) by the amount of miles per lap (2).

14/2 = 7 laps
