Answer:
3.205
Step-by-step explanation:
convert the decimal number to a fraction

To divide by fraction, multiply by the reciprocal of that fraction

Reduce the numbers with the greatest common divisor 9

Calculate the product

Now turn it to a decimal which will be

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.
Answer:
I'm pretty sure it's C
Step-by-step explanation:
Answer:
The values of
and
so that the two linear equations have infinite solutions are
and
, respectively.
Step-by-step explanation:
Two linear equations with two variables have infinite solution if and only if they are<em> linearly dependent</em>. That is, one linear equation is a multiple of the other one. Let be the following system of linear equations:
(1)
(2)
The following condition must be observed:
(3)
After some quick operations, we find the following information:
,
, 
The values of
and
so that the two linear equations have infinite solutions are
and
, respectively.
