Mathematics

Elden [556K]3 years ago
5 0

Answer:

Parallel

Step-by-step explanation:

Let the required lines be y-x = 5 and y = x-1

If y-x = 5

y = x + 5

The slope m = 1

For the line y = x - 1

The slope m is also 1

Since the slope of both lines are the same, hence both liens are parallel

A number,y,is 2 more than 3 times another number,x, the sum of the 2 numbers is 26. What are the two numbers?
Ivanshal [37]
Y = 2 + 3x
x + y = 26

Substitute:
x + (2 + 3x) = 26
4x + 2 = 26
4x = 24
x = 6

6 + y = 26
y = 20

Can someone answer this please!!
Katyanochek1 [597]

Answer:

<u>The perimeter of the square is option E. 16√5 mm.</u>

<u>The area of the square is option A. 80 mm².</u>

Step-by-step explanation:

1. Let's calculate the perimeter of this square:

The perimeter of a square is the sum of its side 4 times, thus:

Perimeter = 4√5 + 4√5 + 4√5 + 4√5

<u>Perimeter = 16 √5</u>

<u>Perimeter = 4 * 4√5 = 16√5</u>

<u>The correct answer is option E. 16√5 mm</u>

2. Let's calculate the area of this square:

The area of a square is the length of its side squared, thus:

Area = (4√5)²

Area = 4√5 * 4√5

Area = (4 * 4 * √5 * √5)

Area = 16 * 5 = 80

<u>The correct answer is A. 80 mm²</u>

Argyle sells computers. He keeps one
Tomtit [17]

Answer:

Note: I'm assuming that he keeps 1/8 of the money spent for himself.

If this is what the question was asking, then the answer would be:

Argyle must sell $4,000 worth of computers.

Step-by-step explanation:

First, we write an equation.

1/8n = $500

Note: n is the variable I'm using to represent the amount of money Argyle must sell to get $500 as commission.

Then, to get the value of n and to get rid of the fraction, we multiply both sides by 8:

1/8n * 8 = $500 * 8

= n = $4000

Therefore, Argyle must sell $4,000 worth of computers to keep 1/8 ($500) as commission.
