In high school Sam grew from 60 inches tall to 74 inches tall. What was Sam's change in height during high school? Write the calculation that determines that change.

1. 14 inches

2. Change in Sam's height = final height - initial height

Step-by-step explanation:

Step 1:

Data obtained from the question:

Sam's initial height = 60 inches

Sam's final height = 74 inches

Change in Sam's height =?

Step 2:

Determination of the change in Sam's height. This is illustrated below:

Change in Sam's height = final height - initial height

Change in Sam's height = 74 - 60

Change in Sam's height = 14 inches

Therefore, the change in Sam's height during high school is 14 inches

The calculation that determine the change in Sam's height is given by:

Change in Sam's height = final height - initial height

the monthly balance will be $75,000

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
