Six times the sum of a number and eight is nineteen. Which of the following equations could be used to find the number?

dezoksy [38]

Answer:

A. 6(n + 8) = 19

Step-by-step explanation:

Look for key words.

6 times the sum of a number and 8 is nineteen.

From these key words it is clear that the solution is 19, you are adding an unknown number (a variable, which we will represent with x) to 8, and multiplying our (x+8) by 6.

Write out the equation.

6(n + 8) = 19

Don't know how clear this is, but I hope it helped you figure this out!
