Question

Find that value of x so that:5,15,x,x+8 are proportional

Answer 1

Answer:

x=4

Step-by-step explanation:

as we know in proportional the product of exremes is equal to the product of means .

extremes=5 and x +8

Means =15 and x

= 5(x+8)=15x

= 5x+40=15x

= 40=15x-5x

=40= 10x

= - 10x = - 40

= 10x =40

= x= 4

Now we check

= 5,15,4,12

= 5×12 =15×4

= 60= 60

= checked
