Answer:

The answer to your question is letter C

Step-by-step explanation:

Data

hamburgers = h

fries = f

soda = s

Student 1         4h + 4f + 1s = 21

Student 2         1h + 1f + 1s = 5

Student 3         1h + 1f        = 5

From the data of students 2 and 3 we can conclude that the system will not have a solution because is not possible that one student has charged 3 items for the same cost of student 3 that bought only 2 items.

Answer:

\frac{7}{18}

Step-by-step explanation:

We want to simplify;

\frac{7}{3}\div6

This can be rewritten as;

\frac{7}{3}\div \frac{6}{1}

We multiply by the reciprocal of the second fraction to obtain;

\frac{7}{3}\times \frac{1}{6}

We multiply to get;

=\frac{7\times1}{3\times6}

=\frac{7}{18}

Jose can read 7 pages of his book in5 minutes. at this rate, how long will it take him to read the entire 175-page book?
Lera25 [3.4K]
Since 7 pages could be in 5 min.
So time required by 1 page 5/7 min.
So time required by 175 pages =175×5/7=125 min.
= 2 hours and 5minutes
