Dan was thinking of a number. Dan divides by 5, then adds 3 to get an answer of 3. What was the original number?

The original number was: x = 0

Step-by-step explanation:

Let 'x' be the number

Given that:

Dan first divides it by 5

x/5

Then adds 3

x/5 + 3

To get an answer of 3

x/5 + 3 = 3

now solving the expression

Subtract 3 from both sides

Simplify

Multiply both sides by 5

Simplify

Therefore, the original number was: x = 0

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
