Which statements are true about the ordered pair (7, 19) and the system of equations?

{2x−y=−5 x+3y=22


Select each correct answer.


The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.

The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.

The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.

The ordered pair (7, 19) is a solution to the system because it makes both equations true.

Step-by-step explanation:

Answer:

5*5=5+5+5+5+5

Step-by-step explanation:

Both are equivalent because both include adding 5 fives together, if you were to space out the 5*5 it would be equivalent. Also, if you add 5+5+5+5+5 it would equal 25 and 5*5=25. That is why they are equivalent. Hope this helps, let me know if correct, and have a great day!!

A school club sold 300 shirts. 31% were sold to fifth graders, 52% were sold to sixth graders, and the rest were sold to teachers. How many shirts were sold to each group-fifth graders, 6th graders, and teachers? Explain or show your reasoning. Please help I'm late on turning in homework!

Answers

Answer:

5th graders = 93 people  6th graders = 156  teachers = 51

Step-by-step explanation:

93 5th graders bought shirts, 156 6th graders bought shirts, 51 teachers bought shirts

300x0.31 = 93 shirts sold to 5th graders
300x0.52 = 156 shirts sold to 6th graders
156+93 = 249 shirts sold to students
300-249 = 51 shirts sold to teachers

Answers

Answer:

Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.

Find and compare the means to the nearest tenth.

7th-grade mean:

✔ 16

5th-grade mean:

✔ 13.4

What is the relationship between the means?

✔ The 7th-grade mean is about 2.5  points higher.

Step-by-step explanation:

Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

What is the Mean of a Data Distribution?

The mean is the average of the data set, that is the sum of each data value divided by the number of data points.

Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.

Mean for 7th Grade Students:

Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21

Mean = 335/21

Mean = 15.95 = 16

Mean for 5th Grade Students:

Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19

Mean = 281/21

Mean = 13.38 = 13.4

The difference between their means = 16 - 13.4 = 2.6.

Hence, Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

HELP! WILL MARK BRAINLIEST IF CORRECT!

Answers

Answer:

72%

Step-by-step explanation:

18/25 = 0.72

0.72 x 100 = 72

Answer:

72%

Step-by-step explanation:

Step 1 we make the assumption that 25 is 100% since it is our output value

Step 2 we next represent the value we seek with x

Step 3 from step 1, follows that 100%=25

Step 4 in the same vein, x%=18

Step 5 this gives us a pair of simple equations: 100% = 25(1)

X%= 18(2)

Step 7: taking inverse of both sides yields

X%\100% = 18/25

—> = 72%

Therefore, 18 is 72% of 25
