Figure out x for the following:
a) 5x + 2 = 22
b) 2(5x - 3) = 50
c) 5(2x + 1) = 50

4, 5.6, 4.5

Step-by-step explanation:

a:

5x + 2 = 22

5x = 20

x = 4

b:

2(5x-3) = 50

10x - 6 = 50

10x = 56

x = 5.6

c:

5(2x + 1) = 50

10x + 5 = 50

10x = 45

x = 4.5

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
