Answer:
43 percent
Step-by-step explanation:
6/14 ×100%
=0.248
=43%
first add up the total people, then substract the total of people to the people that didn't bring them, divide them then multiply it by 100%
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:
w=-11/4 or -2 and 3/4
Step-by-step explanation:
To solve this, we first have to cancel out the dividing by-3. We can use the inverse operation of division, which is multiplication. We have to multiply both sides by -3, and the equation becomes 4w+5= -6. Then, we subtract 5 from both sides. We get 4w= -11. We finally divide 4 on both sides, getting w=-11/4. -11/4 is in improper fraction form and -2 and 3/4 is in mixed number form.
Answer:
<h2>See below</h2>
Step-by-step explanation:
first thing you didn't give any quadratic equation and also didn't allude which method you indeed however I'll give you two methods
- factoring
- quadratic formula
to get elaborately factoring method
see this question which is answered by me
quadratic formula:
by using this formula we can solve quadratic very early
we just need to substitute the value of a,b and c and simply to get x
