Question

*Which of the following conditions on a variable 'b' describes an equation?* 1️⃣ 'b' added to 3 is equal to 4 2️⃣ 'b' divided by 4 is smaller than 25 3️⃣ 4b is greater than 20 4️⃣ 9 subtracted from 'b' is smaller than 8​

Answer 1

Answer:

option no.1 is the answer of the question

Answer 2

Given :  Statements  about variable b

1️⃣ 'b' added to 3 is equal to 4

2️⃣ 'b' divided by 4 is smaller than 25

3️⃣ 4b is greater than 20

4️⃣ 9 subtracted from 'b' is smaller than 8​

To Find :  Which describes an Equation

Solution:

1️⃣ 'b' added to 3 is equal to 4

=>  3  + b = 4

Has variable b and also has sign of equality

so this is an equation in variable b

Hence this describes an equation

2️⃣ 'b' divided by 4 is smaller than 25

=> b/4  <  25

This is an inequality

3️⃣ 4b is greater than 20

=>  4b > 20

This is an inequality  

4️⃣ 9 subtracted from 'b' is smaller than 8​

=> b - 9 < 8

This is an inequality  

Hence correct answer is  'b' added to 3 is equal to 4
