Answer: -2

Step-by-step explanation:

3x+2y=16

x+y=4 multiply by -2

-2x-2y=-8

3x+2y=16  ------a

-2x-2y=-8  -------b

Add equation a and b

(3x+-2x)+(2y+-2y) = 16+(-8)

x+0=8 (y has been eliminated)

bekas [8.4K]

Answer: 75/7 or 10.71 (rounded)

Step-by-step explanation:

Mean = Average

To find the average you should add all the numbers together and then divide it by the amount of numbers.

In this question, the formula is \frac{n_1+n_2+n_3+n_4+n_5+n_6+n_7}{7}

----------------------------------------------------------------------------------------

The list of the first 7 odd prime numbers:

3, 5, 7, 11, 13, 17, 19

Now, add them together

3+5+7+11+13+17+19=75

Divide the sum by 7

75÷7=75/7=10.71 (rounded)

Hope this helps!! :)
