Answer:
I just answered this, was 4.24 sq. in. right?
Step-by-step explanation:
....?
With this information we can set up 2 equations:
x + y = 312 (# of tickets sold for adults + # of tickets sold to adults = 312)
12x + 5y = 2204 ( # of tickets sold for adults times $12 + # of tickets sold to adults times $5 = $2204)
Where x is how many tickets were sold to adults and y how many tickets were sold to children
Now we can solve this system of equations by substitution:
isolate y in the first equation to find its value and plug it in the second equation
x + y = 312
isolate y by subtracting x from both sides:
x - x + y = 312
y = 312 - x
Apply y = 312 - x to the second equation
12x + 5y = 2204
12x + 5( 312 - x) = 2204
12x + 1560 - 5x = 2204
7x + 1560 = 2204
Subtract 1560 from both sides to isolate x
7x + 1560 - 1560 = 2204 - 1560
7x = 644
Divide both sides by 7
7/7x = 644/7
x = 92
Now plugin 92 for x in the first equation to find the value of y
x + y = 312
92 + y = 312
subtract 92 from both sides
92 - 92 + y = 312 - 92
y = 220
x = 92, y = 220
92 tickets were sold to adults and 220 tickets were sold to children

Answer:
g(-4) = 18.
Step-by-step explanation:
Find g(-4): we replace the x in g(x) by -4:
g(-4) = (-4)^2 + 2
= 16 + 2
= 18.
Average speed is 18.6 kilometer per hour
<u><em>Solution:</em></u>
Given that,
To visit the sites, Nathan's family drove 6.8 km, 9.8 km, 20.3 km, and 46.8 km
They drove for 4.5 hour
To find: average speed
<em><u>The average speed is given by formula:</u></em>
![\text{ Average speed } = \frac{\text{ total distance }}{\text{ total time taken }}](https://tex.z-dn.net/?f=%5Ctext%7B%20Average%20speed%20%7D%20%3D%20%5Cfrac%7B%5Ctext%7B%20total%20distance%20%7D%7D%7B%5Ctext%7B%20total%20time%20taken%20%7D%7D)
Here, total distance = 6.8 + 9.8 + 20.3 + 46.8 = 83.7 km
Total time taken = 4.5 hour
<em><u>Substituting the values in formula,</u></em>
![\text{ Average speed } = \frac{83.7}{4.5} = 18.6](https://tex.z-dn.net/?f=%5Ctext%7B%20Average%20speed%20%7D%20%3D%20%5Cfrac%7B83.7%7D%7B4.5%7D%20%3D%2018.6)
Thus average speed is 18.6 kilometer per hour
