Answer:
i think its A
Step-by-step explanation:
divide both sides by -2 which makes the y int -3 and A has a negative slope
B - (5 x 8) - 3
A is adding 3, not subtracting.
C is basically 5 squared.
D is 5 lots of 11.
I'm pretty sure this is Triangle stuff, with Sin, Cos + Tan, etc.
I can't remember it all I'm afraid, but the angle will be the 1 degree, 10 minutes - the Hypotenuse side will be the 3.5 km
Answer:
<em>173 children tickets were sold and 201 adult tickets were sold</em>
Step-by-step explanation:
Let the number of child ticket sold be x
Let the number of adult ticket sold be y
If the total number of ticket sold is 374, hence;
x +y = 374 .... 1
Also if the ticket cost 3$ per child and 5$ per adult with total cost of $1524, this can be expressed as;
3x + 5y = 1524..... 2
Solve both equations simultaneously
From 1; x = 374 - y ...3
Substitute equation 3 into 2
3(374-y)+5y = 1524
1122-3y+5y = 1524
1122+2y = 1524
2y = 1524 - 1122
2y = 402
y = 402/2
y = 201
Since x = 374-7
x = 374 - 201
x = 173
<em>Hence 173 children tickets were sold and 201 adult tickets were sold</em>

We have the expression
![\frac{425xy^4}{25xy^2}](https://tex.z-dn.net/?f=%5Cfrac%7B425xy%5E4%7D%7B25xy%5E2%7D)
We can already simplify x because it's both on the numerator and denominator
![\frac{425y^4}{25y^2}](https://tex.z-dn.net/?f=%5Cfrac%7B425y%5E4%7D%7B25y%5E2%7D)
Now we can simplify 425/25 = 17
![\frac{17y^4}{y^2}](https://tex.z-dn.net/?f=%5Cfrac%7B17y%5E4%7D%7By%5E2%7D)
Remember that
![\frac{a^n}{a^m}=a^{n-m}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5En%7D%7Ba%5Em%7D%3Da%5E%7Bn-m%7D)
Then
![17y^{4-2}=17y^2](https://tex.z-dn.net/?f=17y%5E%7B4-2%7D%3D17y%5E2)
The final result is
