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>
Answer:
minos anos
Step-by-step explanation:
The diagram tells us 3 things: the right angle and the two corresponding side measurements. Because the side measurements are corresponding, we can set a proportion:
6/9=9/15
If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.
To calculate this, we use cross multiplication.
6/9=9/15
6*15=9*9
90=81
90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.
I hope this helps! Please comment if you have any questions.
