Find the value of a and b when x = 10

a = 5x/2

b = 2x * (x - 5) / 10x

a = 5 (10) / 2

a = 50 / 2

a = 25

b = 2 (10) * (10 - 5) / 10 (10)

b = 20 * 5 / 100

b = 100 / 100

b = 1

a=25, b=1

Step-by-step explanation:

This is a substitution question

The value of x is given which is 10

So let's solve the given question

a=5x/2

Since x=10

a=5 (10) / 2

a=50/2

a = 25

To get the value of b

Let's solve the next question given

b=2x * (x-5) / 10x

Since x is 10

Let's substitute

b=2 (10) * (10-5) / 10 (10)

So to solve this we will have to it step by step

b=20*5/100

b=20*0.05

Remember that * means multiply

Therefore

b=20*0.05

b=1

Therefore a is 25 and b is 1
