Answer:

x = 7

Step-by-step explanation:

The diagonals of a rectangle are congruent , so

BD = AC , that is

7x - 18 = 5x - 4 ( subtract 5x from both sides )

2x - 18 = - 4 ( add 18 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

5 times a certain number plus 2 times that number plus 2 is 16 what is the number

maks197457 [2]

let the number be x

ATQ

$\\ \sf\longmapsto 5x+2x+2=16$

$\\ \sf\longmapsto (5+2)x+2=16$

$\\ \sf\longmapsto 7x+2=16$

$\\ \sf\longmapsto 7x=16-2$

$\\ \sf\longmapsto 7x=14$

$\\ \sf\longmapsto x=\dfrac{14}{7}$

$\\ \sf\longmapsto x=2$
