Question

Hey Guys............................solve this ​

Answer 1

ACTIVITY - 1 :-

Let blank be x

1. x + 20= 25

  x = 25 - 20

  x = 5

2. 45 / x = -5

  45 = x * -5

  x = 45 / -5

  x = -9

ACTIVITY - 2 :-

Let blank be x

1. x * 5 > 32

if x = 6

6 * 5 > 32 becomes false

if x = 7

7 * 5 > 32 is true

so x = 7

2. 25 + x < 30

  if x = 4, 29 < 30 is true

  if x = 3, 28 < 30 is true

  if x = 2, 27 < 30 is true

  if x = 1, 26 < 30 is true
