Mario is x years old. In 7 years, he will be 19. Which equation can be used to determine Mario’s present age?(1 point)
Responses
x − 7 = 19
x minus 7 equals 19
x + 7 = 19
x plus 7 equals 19
x − 19 = 7
x minus 19 equals 7
x + 19 = 7
x + 7 = 19
To determine Mario's present age, we can use the equation:
x + 7 = 19
This equation implies that Mario's current age (denoted by x) plus 7 years will equal 19, which is his age in 7 years.
To determine Mario's present age, we need to use the given information that in 7 years, he will be 19.
Let's break down the problem:
- If in 7 years he will be 19, it means he is currently younger than 19.
- To find his current age, we subtract the number of years between now and 7 years ago from 19.
Therefore, the correct equation is:
x - 7 = 19.
This equation states that Mario's present age (x) minus 7 years (time passed) equals 19.
