To find the area you multiply the length by the width.

W = the width, and you are told the length is 5 meters longer, so the length would be (W +5)

Now multiply those together to equal 20,000 square meters:

w(w+5) = 20,000

Slope Calculation (find the slope) Slope form —> y=mx+b (m is slope)<br><br> 3x=7y+21

Sindrei [870]

Solve for y:

3x = 7y + 21

~Subtract 7y to both sides

3x - 7y = 21

~Subtract 3x to both sides

-7y = 21 - 3x

~Divide -7 to both sides

y = -3 + 3/7x

~Change order

y = 3/7x - 3

Best of Luck!

a circus charges $2.50 for kids tickets and $6 for adult tickets last week and twice as many kids attended the circus than adult

aliina [53]

Let
x-----------> the number of kids
y----------> the number of adults

we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300

the answer is
the number of kids is 1300

First multiply each term by 24(the common denominator found by 8×3) to remove the fractions and make things easier.
$24(5) + 24( \frac{x - 2}{3} ) = 24( \frac{x + 3}{8} )$
This will give you,
$120 + 8(x - 2) = 3(x + 3)$
Then just continue to simplify and isolate the variable.
$120 + 8x - 16 = 3x + 9$
$8x + 104 = 3x + 9$
$5x = - 95$
$x = - 19$
