Answer:
<u>375 Adult Tickets.</u>
Step-by-step explanation:
Here, we can simply set up an equation using variable <em>x </em>in place of the unknown student/adult tickets.
x = # of <u>adult</u> tickets sold
x + 65 = # of <u>student</u> tickets sold.
1) x + x + 65 = 815 (set both ticket amounts equal to the total)
2) 2x + 65 = 815 (added common variables together)
3) 2x = 750 (negated the +65, subtracted it from both sides)
4) x = 375 (divided both sides by 2)
5) 815 - 375 = 440 (subtracted the x from the total number of <u>adult</u> tickets, to recieve the amount of <u>childrens</u>' tickets.
Therefore,
Since there were fewer adult tickets sold (-65), 375 is the number of adult tickets, and 440 is the number of student tickets.
He must work 13 hours. I don't feel like showing my work.
To make an equation that solves for the height as according to the volume of a pyramid, you must isolate the variable h on one side.
The first thing you have to do is to multiply both sides by 3 to get 3V=Bh.
Then, divide both sides by B to get your answer as h=3V/B.
Answer:
1 and 1/3
Step-by-step explanation:
I got this because you can first take 13-5 which is 8 then you can divide 8 by 6 to get your final answer.
Hope this helps.
