Step-by-step explanation:

No. of points got from 1 stunt = 50.

No. of points deducted from 1 fail = 40.

6 stunts and 9 falls were gained last week.

So, A/C the number of points earned =

(6×50)-(9×40)

= 300 - 360

= -60

Her score today is 3 times her score from last week so multiply by 3

= (-60) × 3

= -180

If it were multiplied by -3 instead of 3 it would be...

(-60) × (-3)

= 180

The difference would be that on multiplying with positive 3 she would be 180 points in the whole but multiplying with negative three means she is 180 points in the league.

The similarity is that that whole number is same but the symbol adds a difference and the absolute value would be same too.

IrinaK [193]
Answer: 1539.2nm

The space between molecule is going as X-1 function. That mean 1 molecule doesn't have space, 2 molecules have 1 space, 3 molecules have 2 space. Then 105 molecules will be will have 104 space.
Each space is 14.8nm, the total  distance would be: 104 space x 14.8 nm/space= 1539.2nm

2.5(12.75x + 24.50) = 188.75
mrs_skeptik [129]

Answer:

Step-by-step explanation:

First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.

Multiply 2.5 on each side of the equation like this:

(12.75 x 2.5) (24.50 x 2.5) =188.75

Once you're finished, you should get 61.25 and 31.875x =188.75

Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:

61.25 - 61.25 = 0

188.75 - 61.25 = 127.5

So now your equation should look like this:

31.875x = 127.5

You have to divide 31.875 by each side now.

Once you divide them, your final answer should be 4.

so x = 4.

I really hope this helps! ^^
