Answer: Total cost would be $40, and multiplication expression would be

$8\times 5\\\\=\$40$

Step-by-step explanation:

Since we have given that

Number of his friend = 7

Including him, number of persons = 7+1 = 8

Cost of each ticket = $5

We need to find the total cost.

So, Total cost would be

$8\times 5\\\\=\$40$

Hence, total cost would be $40, and multiplication expression would be

$8\times 5\\\\=\$40$

The product of two positive integers us 2005. F neither integer is 1, what is the sum of the two integers?

Brums [2.3K]

Answer:

406

Step-by-step explanation:

Given: product of two positive integers us 2005.

Let the two positive integers be a and b

Now prime factorization of 2005 = 401×5

where both 401 and 5 are prime number and non of them is 1.

So, and b will be 401 and 5 respectively.

Therefore, sum of the two integers a+b = 401+5 = 406

Find the equation of the line shown

liraira [26]

The equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

<h3>What is the equation of a line passing through two given points in a 2-dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

$(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)$

The graph of the picture shows two clear points (4.5. 0) and (0, 9)

$(y - 0) = \dfrac{9 - 0}{0 - 4.5} (x -4.5)\\\\\\(y - 0) = \dfrac{9 }{- 4.5} (x -4.5)\\\\\\-4.5y = 9(x -4.5)\\\\-4.5y = 9x - 40.5\\\\y = -2x + 9$

Hence, the equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

A 12-foot by 15-foot patio is increased by placing a stone border around the patio. The width of the border is the same all arou

Arisa [49]

Complete question :

A 12-foot by 15-foot patio is increased by placing a stone border around the patio. The width of the border is the same all around the patio.The perimeter of the patio after it is expanded is 74 feet. The equation which represents x, the width of the border is 2[(12+2x)+15+2x)]=74. What is the width of the border?

1) 2 1/2 feet

2) 3 feet

4) 5 feet

5) 8 1/2 feet

Answer:

2.5

Step-by-step explanation:

Solving for X in the perimeter equation :

2[(12+2x)+15+2x)]=74

Open the bracket

2[(12 + 2x + 15 + 2x)] = 74

2(27 + 4x) = 74

54 + 8x = 74

8x = 74 - 54

8x = 20

x = 20/8

x = 2.5

Hence, width fo border = 2.5
