To solve, you would need to make two equations and substitute one in for the other. Let a = # of adults, and c = # of children
5a + 2c = 1,220
a + c = 295
a + c = 295
-c -c
a = 295 - c
5(295 - c) + 2c = 1,220
1,475 - 5c + 2c = 1,220
1,475 - 3c = 1,220
1,475 - 3c = 1,220
-1,475 -1,475
-3c = -255
-3c/-3 = -255/-3
c = 85
a + c = 295
a + 85 = 295
-85 -85
a = 210

Answer: ![x=-5](https://tex.z-dn.net/?f=x%3D-5)
<u>Simplify both sides of the equation</u>
![(0.6)(10n)+(0.6)(25)=10+5n(Distribute)\\6n+15=10+5n\\6n+15=5n+10](https://tex.z-dn.net/?f=%280.6%29%2810n%29%2B%280.6%29%2825%29%3D10%2B5n%28Distribute%29%5C%5C6n%2B15%3D10%2B5n%5C%5C6n%2B15%3D5n%2B10)
<u>Subtract 5n from both sides</u>
![6n+15-5n=5n+10-5n\\n+15=10](https://tex.z-dn.net/?f=6n%2B15-5n%3D5n%2B10-5n%5C%5Cn%2B15%3D10)
<u>Subtract 15 from both sides</u>
![n+15-15=10-15\\n=-5](https://tex.z-dn.net/?f=n%2B15-15%3D10-15%5C%5Cn%3D-5)
Answer:38.56
Step-by-step explanation:
tan35=opposite ➗ adjacent
0.7002=27 ➗ x
Cross multiplying we get
0.7002(x)=27
Divide both sides by 0.7002
0.7002x ➗ 0.7002=27 ➗ 0.7002
x=38.56041131
x=38.56 nearest hundredth
