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.
This is a 30, 60, 90 triangle. One angle measures 30° and the other measures 90°. The other has to be 60° because all triangles are 180°. These triangles have special rules:
Say the side opposite 30° (in this case, y) is equal to 1
The side opposite the 60° (in this case, x) is equal to √3
The side opposite 90° is 2.
If 16√3 is opposite 90°, then opposite 30° would be half of that. Therefore, y = 8√3.
Now we need to multiply y by √3 to get x, because the side opposite 60° is always that of 30° multiplied by √3.
8√3 * √3 = 24 as the √3s cancel and become 3. So 8 multiplied by 3 makes 24.
Therefore, x = 24.

Answer:
The inequality is 
Step-by-step explanation:
Given:
The inequality to solve is given as:
Now, in order to solve it for 'x', we need to isolate 'x' on one side of the inequality.
<em>Adding -8 on both sides, we get:</em>
<em>Dividing both sides by 6, we get:</em>
Therefore, the inequality for 'x' is given as:
So, 'x' include all the values that are greater than -1.
