A.(-1,8)
B.(0.5,5)
C.(8,-1)
D.(5,0.5)

Answers

Answer 1
Answer:

Answer:

C. (8, -1)

Step-by-step explanation:

{y = ¼x - 3}

{2x + 4y = 12

2x + 4[¼x - 3] = 12

2x + x - 12 = 12

3x - 12 = 12

+ 12+ 12

_________

3x = 24

____

33

x = 8 [Plug this back into both equations above to get the y-coordinate of −1]; -1 = y

What is 1/5 of 40???????????

Answers

Answer:
8

Explanation:
To get a fraction of a number, we will simply multiply this fraction by the number.

In the given we want to find (1)/(5) of 40.

This can be computed as follows:
(1)/(5) of 40 = (1)/(5) * 40

= (40*1)/(5)

= (40)/(5)

= 8

Hope this helps :)

After calculating the fraction (one-fifth) of 40, the answer is 8.

What is the fraction (one-fifth) of 40?

To calculate one-fifth of 40, we divide 40 by 5. When we divide 40 by 5, we get the result 8. Therefore, the fraction (one-fifth) of 40 is equal to 8.

Let's break it down further to understand the process.

One-fifth represents dividing a whole into five equal parts. When we divide 40 by 5, we are essentially splitting 40 into five equal parts. Each part will be the same size.

To divide 40 by 5, we start with the number 40 and divide it by 5.

40 ÷ 5 = 8

The result, 8, represents one-fifth of 40. This means that if you take 40 and divide it into five equal parts, each part will be 8.

Therefore, 1/5 of 40 is equal to 8.

Explain how you can use a number line to show that 5/8 is greater than 3/8

Answers

Hi!

So here's how you'd visualize it!

<---------|---------|---------|---------|---------|---->
  0      1/8       2/8       3/8       4/8       5/8

As represented in the number line, 5/8 is farther up the number line than 3/8, meaning that 5/8 is larger than 3/8.
