Question

2. Write an equation for each situation:
(a) x less than 3 is 9
(b) Addition of 2 consecutive numbers is 11
(c) p subtracted from 10 gives 7
(d) 3 times 2x is 12
(e) c divided by 5 gives -1
​

Answer 1

Answer:

Pls mark me as brainliest

Step-by-step explanation:

(a) x - 3 = 9

(b) 5 + 6 = 11

(c) 10 - p = 7

(d) 2x X 3 = 12

(e) c/5 = -1

Answer 2

3 - x = 9 is the equation for 'x less than 3 is 9'​

Others equations and their solutions are:

x + (x + 1)  = 11   Hence numbers are 5 and 6

10 - p = 7  => p = 3

3 (2x) = 12  => x = 2

c /5 = - 1  => c = -5

Given:

• Statements
• x less than 3 is 9
• Addition of 2 consecutive numbers is 11
• p subtracted from 10 gives 7
• 3 times 2x is 12
• c divided by 5 gives -1
• ​

To Find:

• Equation for the given statements

Solution:

Step 1:

x less than 3 means x is subtracted from 3 hence

3 - x

Step 2:

x less than 3 is 9 Hence 3 -x to be equated with 9

3 - x = 9

3 - x = 9 is the equation for 'x less than 3 is 9'​

Additional Info:

3 - x = 9

=> 3 - 9 = x

=> -6  = x

Hence value of x is -6

Similarly for others

• x + (x + 1)  = 11   Hence numbers are 5 and 6
• 10 - p = 7  => p = 3
• 3 (2x) = 12  => x = 2
• c /5 = - 1  => c = -5
