If someone were to need more than one notebook, and each cost $2, you could use the equation c = 2n to find the total cost, c, of the notebooks, n. 2 multiplied by the number of notebooks would give you your total cost.

Ken normally leaves work at 5:00 pm, but he is leaving 20 minutes late today. He decides to make up time by taking the toll road

kobusy [5.1K]

Answer:

The correct answer is: $y=\frac{1}{3} x + 20$

Step-by-step explanation:

As stated in the question that x represents the number of minutes his normal commute takes. Here the keyword is normal; in the normal commute, Ken takes side streets instead of the toll road.

However, in this scenario, we have to come up with the equation that takes Ken's commute via toll road.

Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:

$x_{toll\_road}=\frac{1}{3}x$

Without considering Ken getting late, the equation would become the following:

$y=\frac{1}{3} x$ --- (A)

As Ken is leaving late, we have to incorporate that time as well by adding it in the aforementioned equation (A).

In this case, it's 20 minutes; therefore, the equation (A) will become:

$y=\frac{1}{3} x+20$

Hence, the correct answer is $y=\frac{1}{3} x + 20$ .

There are a total of 64 students in a drama club and a yearbook club .The drama club has 10 more students than the yearbook club

tatiyna

Answer:

x + y = 64

x + 10 = y

Step-by-step explanation:

Since it isn't asking for the solutions, I won't solve.

let y represent drama students, and x represent the yearbook students.

We know that DS (drama students) plus YS (Yearbook students) equals 64 students in total. To write this mathematically you would write x(YS)+ y(DS) = 64 (Students in total) except just x + y = 64.

The second part of this system explains what y is.

We know that the drama club has 10 more students than yearbook students, so YS plus 10 equals the amount of DS. To write this mathematically you would write x + 10 = y.

Combine the two systems by writing

x + y = 64

x + 10 = y

P.S. Let me know if you need the system solved.
