Answer: the price for an adult ticket is $3

Step-by-step explanation:

Let x represent the price of one adult ticket.

Let y represent the price of one child ticket.

The Martinez family went to play and paid $13 for 1 adult and 4 children. This means that

x + 4y = 13 - - - - - - - - - - -1

The Hernandez family went to the same place and paid $14 for 3 adults and 2 children. This means that

3x + 2y = 14 - - - -- - - - - - - -2

Multiplying equation 1 by 3 and equation 3 by 1, it becomes

3x + 12y = 39

3x + 2y = 14

Subtracting, it becomes

10y = 25

y = 25/10 = 2.5

Substituting y = 2.5 into equation 1, it becomes

x + 4 × 2.5 = 13

x + 10 = 13

x = 13 - 10

x = 3

Area of the entire rectangle =x^2+10x+24

Solution:

Area of the blue box =  length × width

                                  =x\times x

Area of the blue box =x^2

Area of the pink box =  length × width

                                  =4\times x

Area of the pink box =4x

Area of the green box = length × width

                                     =6\times x

Area of the green box =6x

Area of the orange box = length × width

                                       =6\times 4

Area of the orange box = 24

Total area of the rectangle =x^2+4x+6x+24

                                             =x^2+10x+24

Area of the entire rectangle =x^2+10x+24

Walter wants computer software that cost $129. He has $57 saved. If he saves a maximum of $15 a week, the following inequality c
Lina20 [59]

In this question, it is given that

Walter wants computer software that cost $129. He has $57 saved.

he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

15x+57 \geq  129

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

15x\geq  72

Dividing both sides by 15.

x \geq   4.8\

Correct option is A.

Together, a house and the lot it is on costs $40,000. If the house costs seven times as much as the lot, how much does the lot c
padilas [110]

The lot costs 5000 dollars.

<u>Step-by-step explanation:</u>

The cost of a House and the lot = $40,000.

Let us assume the cost of lot as 'x'

Given that, The cost of the house is 7 times as much as the lot.

Therefore, The cost of the house= 7x

The cost of both the house and the lot= x + 7x

$40,000 = x + 7x

40,000 = 8x

x = 40,000/8

x = 5,000

The lot costs $5000.
