Answer:
29/30
Step-by-step explanation:
first, we must make sure they have the same denominator!
2/3 x 10/10 = 20/30
3/10 x 3/3 = 9/30
20/30 + 9/30 = 29/30
Step-by-step explanation:
1 300 × 2.95/100× 4 = $153.40
For example a stands for the number of adult tickets, and s stands for the number of student tickets.
Write a system of equation based on the problem
An equation for "<span>A total of 679 tickets were sold for the school play"
</span>∴ a + s = 679 <em>(first equation)</em>
An equation for "<span>there were 71 fewer student tickets sold than adult tickets"
</span>∴ s = a - 71 <em>(second equation)</em>
<span>
Find the solution of the system
Subtitute s with a - 71 in the first equation to find the value of a
a + s = 679
a + a - 71 = 679
2a - 71 = 679
2a = 679 + 71
2a = 750
a = 750/2
a = 375
The number of adult tickets sold is 375</span>
