Explanation:
Let’s take kids as x and adults as y
According to the question,
5x + 2y = 25 (1)
3x + 1y = 14 (2)
Let’s multiply (2) with 2 so take we can solve the equations
5x + 2y = 25
6x + 2y = 28
(-) (-) (-)
___________
-1x = = -3
x = 3
Substituting to get y
3x + 1y = 14
3(3) + y = 14
y = 14-9
y = 5
Answer:
Therefore, each child’s skate rental (x) costs $3 and each adults’s skate rental (y) costs $5

Answer:
b) in the vertex.
Step-by-step explanation:
In the vertex. If the parabola opens up or down the axis of symmetry is x = a where a is the x coordinate of the vertex.
If it opens to the left or right the axis is y = a where a is the y-coordinate if the vertex.
Answer:
432 feet
Step-by-step explanation:
The total length of line he will draw is equivalent to the perimeter of the plane shape he is drawing. Given that it is a soccer field measured as 96 feet by 120 feet, the shape is a rectangle.
The perimeter p of a rectangle whose length is l and width is b is given as
p = 2(l+b)
Hence the length of the line he must draw
= 2(96 + 120)
= 2 * 216
= 432 feet
