What multiple of 7 is also a factor of 7
enyata [817]
<span>The answer is 7. Seven is a prime number, which means that its multiples are 1 and itself (7): 7 = 1 * 7. To find out which one is a factor of 7, we should divide each of them by 7. 1/7 will be a decimal number and 7/7 = 1, which is a whole number. Thus, 7 will be a multiple of 7 and also a factor of 7.Hope this helps. Let me know if you need additional help!</span>

Tickets to the fashion show we're $2.50 for adults and $1 for students. The receipts were $674 for 302 tickets sold. How many ad
rodikova [14]

Answer:the number of adults that attended the show is 248

the number of students that attended the show is 54

Step-by-step explanation:

Let x represent the number of adults that attended the show.

Let y represent the number of students that attended the show.

Total number of tickets that were sold is 302. This means that

x + y = 302

Tickets to the fashion show were $2.50 for adults and $1 for students. The receipts for all the tickets were $674. This means that

2.5x + y = 674 - - - - - - - - - 1

Substituting x = 302 - y into equation 1, it becomes

2.5(302 - y) + y = 674

755 - 2.5y + y = 674

- 2.5y + y = 674 - 755

- 1.5y = - 81

y = - 81/- 1.5

y = 54

Substituting y = 54 into x = 302 - y, it becomes

x = 302 - 54 = 248
