The answer could be A plzzzz tell me if im wrong.
hope this helped :)
20 adults and 50 kids.

Ax+By=C [Use the standard form of a linear equation]
x+y=C so, x+(C-x)=C [also use this formula]
.
$5.50x+$4.00y=$310 [plug-in the values]
Since x+(C-y)=C, than x+y=70 or x+(70-x)=70
.
5.50x+4.00(70-x)=310 [substitute (70-x) for y and simplify]
5.50x+280-4x=310
5.50-4=310-280 [solve for x]
1.5x=30
x=20 adults
and
y=(70-x)=70-20=50 kids under 12.
Answer:
1.- If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
2.- The square root of a number is that number which when multiplied by itself two times gives us that number.
Example:
Let us use the square root of 64.
√64 = x , so that (x)(x) = 64
We know that, (8)(8) = 64
∴ √64 = 8
The cube root of a number is that number which when multiplied by itself three times gives us that number.
Example:
Let us use the square root of 64
∛64 = x , so that (x)(x)(x) = 64 ,
We know that, 4 x 4 x 4 = 64
∴ ∛64 = 4
Answer:
Option B. Amplitude =3 midline is y =2.
Step-by-step explanation:
In the graph attached we have to find the amplitude and midline of the periodic function.
Amplitude of the periodic function = (Distance between two extreme points on y asxis)/2
= (5-(-1))/2 = (5+1)/2 =6/2 =3.
Since amplitude of this function is 3 and by definition amplitude of any periodic function is the distance between the midline and the extreme point of wave on one side.
Therefore midline of the wave function is y=2 from which measurement of the amplitude is 3.

So multiply 5x6 to get 30
Then times 6x3 to get 18
Next times 4x9 to get 36
Add 30, 18, and 36 together to get
84
