Question

C c. 20 added to 5 times a number is 64 twice the number find the number​

Answer 1

Answer:

21.6

Step-by-step explanation:

As per given in the question it is asked to find the number

following data is given as follows

20 + 5x=64 x 2

this equation is made as it is given in the question

now here we want to find the value of x

so

$20+5 x =64\times 2\\5x =128-20\\5x=108$

hence for finding the value of x we simply shift the value which is with x to denominator

$x =\frac{108}{5} \\x =21.6$

so  the number is 21.6
