Answer:
- 1
Step-by-step explanation:
( x, y ) = ( 2, y )
x = 2
2x - 8y = - 4
Divide 2 on both sides,
( 2x / 2 ) - ( 8y / 2 ) = - 4 / 2
x - 4y = - 2
Substitute x = 2,
2 - 4y = - 2
- 4y = - 2 - 2
- 4y = - 4
y = - 4 / - 4
y = - 1
Answer:
the radius of the inflated balloon is:
Step-by-step explanation:
Since it is stated that the water balloon has a spherical shape: We can confidently use the formula for the volume of a sphere to calculate the radius.
Volume is denoted as 'V' and radius is denoted as 'r'.
Volume is 176,868 mm^3
Now we can solve for the radius r.
cube root both sides
the radius of the inflated balloon is:
Let a and c represent the numbers of adult and children's tickets sold, respectively. The system of equations will have one equation for revenue and one equation for number of tickets.
The revenue equation is
18a +9c = 4959
The number of tickets equation is
a + c = 319
