Whats the answer to these? (These are called Proper fractions.)

AnnZ [28]

Answer:

1: 7/10

2: 3/10

3: 4/8 (2/4 or 1/2 if you need to simplify it)

Step-by-step explanation:

1: Convert 2/5 to tenths by multiplying the denominator and numerator by two. 3/10 plus 4/10 is 7/10

2: Convert 4/5 and 1/2 to tenths.

4/5 is going to be 8/10, 1/2 is going to be 5/10.

Subtract 5/10 from 8/10 to get 3/10

3: Convert 1/4 to eighths to get 2/8. Then add 2/8 and 2/8 to get 4/8.

What is the slope of the line that passes through the pair of points (-7.1,11.4) and (-3.1, 3.4)

salantis [7]

Slope of line passing through given points (-7.1, 11.4) and (-3.1, 3.4) can be calculated as below

(3.4 - 11.4)/ (-3.1 - (-7.1)) = -8/4 = -2

Given equation is in slope form of the line, i.e y = (-3/4)x + 3; By rearranging terms in the equation we can get its standard form as

4y = -3x + 12, which is same as 3x +4y = 12

Worth LOTS OF POINTS PLZ! Is -1/2n+ 1 1/2n+3-n equivalent to 3 ? Explain

Saige's spaceship traveled 588588588 kilometers (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis i

lesantik [10]

Answer:

A is proportional

B and C are NOT proportional

Step-by-step explanation:

First, simplify 588 and 60:

588 divided by 6

60 divided by 6

= 98

Simplify them again by dividing them both by 2

= 49

Let's look at A:

441 and 45

Simplify by dividing by 9

= 49

It's pretty obvious that A is proportional because the simplified values are exactly the same.

Next, let's check B:

215 and 25

Simplify by dividing by 5

= 43

Now that its simplified you can compare

43 is smaller than 49

5 5

B is not proportional

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= 51

Make 51 and 49 have the same denominator so we can compare them

10 5

51 can stay the same because 5 times 2 equals 10

49 times 2

5 times 2

= 98

Now that the denominators are the same we can compare

51 is much smaller than 98

10 10

Therefore, C is also not proportional.

Hope that helps :D
