1. x = cost of one adult ticket
y= cost of one child ticket

2x+3y=31.60
x+2y=18.60 l multiply by -2

2x+3y=31.60
-2x-6y=-37.2
-3y=-5.6
y=1.87

2x+3(1.87)=31.60
2x+5.6=31.60
2x=31.60-5.6
2x=26
x=26/2
x=13

Answer: The adult ticket is $13 and the child ticket is $1.87

Nesterboy [21]

Answer:

  7.5 meters

Step-by-step explanation:

As with many quadrilaterals, pairs of sides have the same length, so the perimeter is twice the sum of two of the sides.

In a kite, generally, opposite sides have different lengths, so the perimeter is twice the sum of the lengths of opposite sides. That is

  51 m = 2(18m + side opposite)

  15 m = 2 × (side opposite)

  7.5 m = side opposite

_____

<em>Comment on side lengths</em>

In a rectangle or parallelogram, the perimeter is twice the sum of adjacent sides. A kite is different in that adjacent sides may be the same length. If the kite is not a rhombus, <em>opposite</em> sides are <em>always</em> different lengths.

natima [27]

Step-by-step explanation:

It is given that,

An aquarium is in the shape of a rectangular prism. The area of the base of the aquarium is 250 square inches.

We need to find the volume of the aquarium.

The formula for the volume of the rectangular prism is given by :

V = lbh

Where, l is length, b is width and h is height

Let the height of the prism is h inches. So,

V = A × h   (As Area, A = lb)

V = 250× h

= (250h) inch³

By substituting the value of h, we can find its volume.

Hence, the volume of the aquarium is (250h) inch³.
