Help plz with Algebra question I attached a file

astraxan [27]

Answer:

x=4.63

Step-by-step explanation:

Area = (1/2) (base) (height)

20 = (1/2) (x+4) (x)

40 = x²+4x

x²+4x-40=0

Put in quadratic equation:

x= $\frac{-4(+/-)\sqrt{4^{2}-4(1)(-40) } }{2(1)}$

x= $\frac{-4(+/-)\sqrt{176} }{2}$

x=4.63324958071 or x=-8.63324958071

Since x can't be negative in this case we take our answer to be 4.63324958071, which rounds to 4.63

A zoo in oklahoma charged $22 for adults and $15 for children. During a summer day, 732 zoo tickets were sold, and the total rec

Vlad [161]

Answer: Cost of tickets for adults = $22

Cost of tickets for children = $15

Total number of tickets sold = 732

Total receipts = $12,912

Let x be number of adult ticket's sold and y be the number of child ticket's sold.

Therefore, we have:

$x+y=732$ --------------- equation 1

$x=732-y$

Also, we have:

$22 x+15y=12,912$

Now, let's substitute the value of x:

$22 (732-y)+15y=12912$

$16104-22y+15y=12912$

$16104-7y=12912$

$7y=16104-12912$

$7y=3192$

$y=\frac{3192}{7} =456$

Now, let's substitute the value of y=456 in equation 1, we have:

$x+456=732$

$x=732-456$

$x=276$

Therefore, the number of child ticket's sold is 456 and number of adult ticket's sold is 276
