So we cant do anything until the 'y' in the 2nd problem is by the 2x. So after we move the 2x over the equation will look like this, "-2x+y=-6."
Now that that is set up we can make our equation.
(12x+5y=30) - (-2x+y=-6)
We have to multiply the second equation by -6 in order to cancle out the X's. That comes out to (12x-6y=36)
Now the equation looks like (12x+5y=30) - (12x+6y=36)
After you subtract you have (-y=-6)
divide by (-1) and you're left with y=6
So 2680 divided by 100 is 26.80 which is 1%, times 26.80 by 5 to get 5% = £134, £2680+134= £2814
Answer:
Step-by-step explanation:
Let the number be y & reciprocal simply means inverse of the number
4×1/y=2×1/8 solving for y
4/y=2/8; y = 16
A.) it is possible to roll a number greater than 1 on a six sided number cube. - So it is likely.
B) It is possible to roll a 1. - So it is likely.
C) It is possible to get a heads when flipping a coin. - So it is likely.
D) It is possible to choose a X, Y or Z from the alphabets. - So it is likely.
Am sorry did not see any one that is neither likely nor unlikely.
There is likelihood in each of the Event, but to some varying degree.
I hope this helps.
