C is the answer all you had to do was
31.80-4.00
Which is 27.80
Then add 2.50
Which is 30.3!
Answer:
{x + y= 239
{15x + 5.50y = 2758.50
Step-by-step explanation:
x = adults y = children and the total amount of people is 239.
$15 for adults and $5.50 for children and the total cost equals $2758.50.
From the system of equations, we have 3 unknowns and 3 equations. Therefore, it can be solved.
<span>3x - 2y + 2z = 30 (1)
</span><span>-x + 3y - 4z = -33 (2)
</span><span>2x - 4y + 3z = 42 (3)
We can write equation 2 x as a function of y and z and substitute the new equation to the other equations.
</span>x =3y - 4z + 33 (2)
3 (3y - 4z + 3)<span> - 2y + 2z = 30 (1)
</span>2 (3y - 4z + <span>3)</span> - 4y + 3z = 42 (3)
We simplify and solve the equations and we get values,
x = 4
y = -7
z = 2
<span>1/4(x + 16) - x =
First, distribute the 1/4.
= 1/4x + 1/4 * 16 - x
= 1/4x + 4 - x
= 1/4x + 4 - 4/4x
= 1/4x - 4/4x + 4
= -3/4x + 4

Answer:
3/6 or 1/2
Step-by-step explanation:
y2-y1 = 8-2 = 6
x2-x1 = 3-0 = 3
The point would be (3,6) or if simplified (1,2)
HOPEFULLY THIS HELPED :)
