Answer:

15x-6y=48

Step-by-step explanation:

So we have the system of equations:

5x-2y=16\\15x-7y=51

And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.

We can see that the coefficient of x in the second equation is 15.

So, to match 15, we must multiply the first equation by 3. So:

3(5x-2y)=3(16)

Multiply:

15x-6y=48

And we're done!

Answer:

Step-by-step explanation:

-15x + 6y = -48

15x - 7x = 51

-x = 3

x = -3

5(-3) - 2y = 16

-15 - 2y = 16

-2y = 31

y = -15.5

(-3, -15.5)

What number must be added to 15,-6,&amp; 12 to have a mean of 5?<br> EXPLAIN!!
FrozenT [24]
To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.

15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been

The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20

So take the 21 from before, and if you add -1, you get 20!

So, x= ➖1⃣!!!!!!! (That's a -1)

MaRussiya [10]

Answer:

32768 ways

Step-by-step explanation:

Given

Marbles = 8 marbles

Selection = 5 (with replacement)

Required

Determine the number of ways

Because it is a selection with replacement; each selection is as follows:

First = 8\ marbles

Second = 8\ marbles

Third= 8\ marbles

Fourth = 8\ marbles

Fifth = 8\ marbles

Total number of ways is then calculated as:

Total = 8 * 8 * 8 * 8 * 8

Total = 32768
