Answer:
1 hour and 30 minutes.
Here's how I did it:
960/3 = 220
220 = 30 minutes
220 = 30 minutes x 3 = 960
30x3=90
90 has to be converted into minutes and hours
so 90 = 1:30
Write the system of equation based on the problem
"A total of 345 tickets that consists of adult tickets and students ticket were sold" could be written as:
∴ a + s = 345 <em>(first equation)</em>
"<span>the number of student tickets sold was two times the number of adult tickets sold" could be written as:
</span>∴ s = 2a <em>(second equation)</em>
<span>
Solve the system of equation
Substitute 2a as s in the first equation
a + s = 345
a + (2a) = 345
3a = 345
a = 345/3
a = 115
There are 115 adult tickets sold.</span>
<u>ANSWER:
</u>
The value of x after evaluating the given equation x + 6 - 5 = 8 - 2 is 5.
<u>SOLUTION:
</u>
Given, equation in one variable is x + 6 – 5 = 8 – 2
And, now, we have to find the value of the variable x in the equation by solving the given equation.
So, let us solve the given equation for x.
Then, x + 6 – 5 = 8 – 2
x = 8 – 2 – (6 – 5) [sending all the numerical terms on left side to the right side.
x = 8 – 2 – 6 + 5
x = 8 + 5 – 2 – 6
x = 13 – 8 = 5
Hence, the value of x after evaluating the given equation is 5.
