C.) 5, Using P.E.M.D.A.S you have to multiply first, so replacing the variable X with 5, it should look like this: (6*5) -3=27.  6*5 is 30, 30 subtracted by 3 is 27.

An open sentence is one that becomes true (or false in varying scenarios). In this situation, that means that you would want the equation to be 27 = 27.

Therefore, the correct answer is C. 5.

This is because it creates the equation 30 - 3 = 27 which simplifies to 27=27.

Hope this helps! :)

Richard and Teo have a combined age of 26 . Richard is5 years older than twice​ Teo's age. How old are Richard and​ Teo?
loris [4]

Answer:Teo's age = 7 years ,Richard's age = 19 years

Step-by-step explanation:

Step 1

Let Teo's age be represented as x

Such that Richard 's age = 5 + 2x

and their combined ages equaling 26 can be expressed as

x + 5+ 2x = 26

Step 2 --- SOLVING

x + 5+ 2x = 26

3x+ 5= 26

3x= 26-5

3x= 21

x = 21/3

x = 7

Teo's age = 7 years

Richard's age = 5+2x= 5 + 14= 19 years
