Answer:
290 adults and 190 children attended the Play.
Step-by-step explanation:
Given:
Total number of people in play = 480
Let the number of adults be x
and Number of children be y
Hence we can write the equation as;
Also Given:
Price for 1 adult = $2
Price for 1 children = $1
Total admission receipts = $770
Hence we can write the equation as;
Now We will subtract equation 1 from equation 2 we get;
Now substituting the value of x in equation 1 we get;
Hence 290 adults and 190 children attended the Play.
Answer:
The common difference is 4.
Step-by-step explanation:
You get to term number n by starting with term number 1 and adding the common difference d n-1 times.
A work applied on the cart = 20.8x0.636
I have not done this in advance. I'm just going to write it down
and see what I can do with it:
[ 1/(x+3)² - 1/x² ] / 3
Multiply the top and bottom by (x+3)² :
[ 1 - (x+3)²/x² ] / 3 (x+3)²
Multiply the top and bottom by x² :
[ x² - (x+3)² ] / 3 x² (x+3)²
Now it's just a matter of expanding and cleaning things up,
and hope and pray that a lot of things cancel.
Eliminate the parentheses on top and bottom:
[ x² - x² - 6x -9 ] / 3 x² (x² + 6x + 9)
Combine the x² terms on top, and divide top and bottom by 3 :
[ - 2x - 3 ] / x² (x² + 6x + 9)
Finally, all I can make of this is:
- (2x + 3) / [ x(x+3) ]² .
That's not a whole lot prettier than the original form, but at least
we got rid of those fractions in the numerator of a fraction.
I hope this is some help to you.
