I would assume it's the area of both the sidewalk and pool combined (79ft x 49ft = 3,871) minus the area of the pool alone (75ft x 45ft = 3,375). The area of the sidewalk would then be
496 ft

Answer:
6 children
Step-by-step explanation:
If all of the group were adults, the total cost of tickets would be 8×$10 = $80. The actual cost was $80 -62 = $18 less than that. Since each children's ticket saves $3 off the cost of an adult ticket, there were $18/$3 = 6 children's tickets.
There were 6 children in the group.
_____
If you want an equation, you can let c represent the number of children. Then the cost of tickets is ...
8(10 -c) +5c = 62 . . . . 10-c is the number of adults
-3c = -18 . . . . . . . subtract 80
c = -18/-3 = 6 . . . divide by 3
The equation for slope is <u>y² - y
</u> x² - x
So it would be: <u>8 - (-20)</u> or <u>8 + 20
</u> 5 - 3 5 - 3
<u>28</u>
2
Then, you have to reduce it, divide both by two.
<u>14</u>
1
Since it is over 1, then it is just the numerator.
Your final is:
<em>Slope = 14</em>
Step-by-step explanation:
15 percent of solution = 12 × 0.15 = 1.8 Gallons of bleach
12 - 1.8 = 10.2 Gallons of water
