Answer: 3/7

The slope is the same.

Parallel lines have completely opposite slopes!!
By this, positives become negatives, and negatives become positives, as well as being flipped.
3/7 would flip and become negative to become F, -7/3!

For future reference, this works with whole numbers too, like 3 becoming -1/3.

Hope this helps you!

Round off 3. 55 to one significant figure
Anika [276]

Answer:

3.6

Step-by-step explanation:

We must first clarify how a number is rounded.

To round a number to unity we have to look at the first number after the comma.

If this number is less than 5 (1, 2, 3, 4) we should not do anything, but if that number is 5 or greater (5, 6, 7, 8, 9) we must add a unit to the number.

That is to say:

<5 do nothing

=> 5 round to the next number (+1)

So in the case of 3.55 it would be.

3.55 = 3.6

sergejj [24]

Answer:

B. 10    E. 20   C. 60

Step-by-step explanation:

s = 2f

t = 2(f + s)

(15 + 15 + 30 + f + s + t)/6 = 25       This equation and the equations above show how the variables relate to each other

f = 10               The first number is 10

s = 2(10)=20   The second number is 20

t = 2(10 + 20) = 60   The third number is 60

Negative 1X minus 4X equals -4 minus 4X +4+5
Bond [772]

Answer:

X = - 5

Step-by-step explanation:

The above word problem is mathematically interpreted thus:

-1X - 4X = -4 - 4X + 4 + 5

-5X = - 4 - 4X + 4 + 5

-5X = - 4 - 4X + 9

Collect like terms

-5X + 4X = - 4+ 9

-X = 5

X = - 5
