Answer:

Therefore, Sara’s current age (5 years later) is 19 years old.

Step-by-step explanation:

Let xx be Sara’s age five years ago. Therefore, Sara’s aunt’s age 5 years ago is 4x4x.

The difference in their ages is a constant, no matter how many years have gone by. (Can you see why?)

4x−x=42

3x=42

x=42/3

x=14

14+5=19

Therefore, Sara’s current age (5 years later) is 19 years old.

students at river view middle school are allowed to wear two different colors of uniform shirts. A survey of students at the sch
Vladimir79 [104]

Answer:

18 students are likely to be wearing red

Step-by-step explanation:

From the question, we know a student either wears red , or blue, with the probability of a student wearing red is 3 times more probable than wearing white.

So, let’s say out of the 24 students, x of them are wearing white. What this practically mean is that 3 * x = 3x of the students would be expected to be wearing red.

Now, adding the number of people wearing red and white together in terms of x, we have x + 3x = 4x

We equate this to 24; 4x = 24 and x = 24/4; x = 6

The number wearing red probably is 3 * x = 3 * 6 = 18 people
