Find the value of a and b when x = 10

a = 5x/2

b = 2x*(x – 5)/10x

The value of a and b when x = 10 are 25 and 1 respectively

GIven the functions

a = 5x/2  

b = 2x*(x – 5)/10x

If the value of x is 10, then;

a = 5(10)/2

a = 50/2

a = 25

Get the value of "b"

b = 2x*(x – 5)/10x

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

b = 20(5)/100

b = 100/100

b = 1

Hence the value of a and b when x = 10  are 25 and 1 respectively

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

3; 9 is 8 to -4

step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
