Question

identify the constant and variable in 18m2y5​

Answer 1

Answer:

Constants - 18,2 and 5. Variables - m and y.

Answer 2

Step-by-step explanation:

1. What is the value of x in the given equation x+10=5

Solution: Given,

x+10 = 5

x = 5-10

x = -5

2. Find constant and variables in the given expression.

(i) 3x = 9

(ii) x – y = -10

Solution:

(i) In 3x = 9,

x is the variable and 9 is the constant.

If we further simplify the equation,

3x = 9

x = 9/3 = 3

then x is the variable and 3 is the constant.

(ii) x-y = -10

Here, x and y are the variables and -10 is the constant value.
