Solve the system x+3=22 2x-y=2

steposvetlana [31]

Hello from MrBillDoesMath!

Answer:

x = 19, y = 36

Discussion:

x + 3 = 22 (*)

2x - y = 2 (**)

Subtract 3 from both sides of (*)

x + 3 -3 = 22 = 3 = 19 =>

x = 19

Substitute x= 19 in (**)

2(19) - y = 2 =>

38 - y = 2 => (add y to both sides)

38 -y + y = 2 + y =>

38 = 2 + y => (subtract 2 from both sides)

38 -2 = 2 -2 + y =>

36 = y

Choose the answer that validates that the rate of change is constant by showing that the ratios of the two quantities are propor

docker41 [41]

Given:

The table of values is

Number of Students : 7 14 21 28

Number of Textbooks : 35 70 105 140

To find:

The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.

Solution:

The ratio of number of textbooks to number of students are

$\dfrac{35}{7}=5$

$\dfrac{70}{14}=5$

$\dfrac{105}{21}=5$

$\dfrac{140}{28}=5$

All the ratios of the two quantities are proportional and equivalent to the unit rate.

Let y be the number of textbooks and x be the number of students, then

$\dfrac{y}{x}=k$

Here, k=5.

$\dfrac{y}{x}=5$

$y=5x$

Hence the rate of change is constant that is 5.
