The solution of the given equation is (3,6). The correct option is B.(3,6)

<h3>Given equations,</h3>

y=x+3.......(1)\\4x+y=18.....(2)

<h3>How to solve the equations?</h3>

putting the value of y from equation (1) in equation (2) , we get

4x+x+3=18\\5x=18-3\\5x=15\\x=3

substitute the value of x=3 in equation (1) we get,

y=3+3\\y=6

Hence, the solution of given equation is (3,6).

So, the correct option is B.

Medain of 38,42,77,47,74,51,48,41,82,72,74,129
uranmaximum [27]

Answer:

The median of 38, 42, 77, 47, 74, 51, 48, 41, 82, 72, 74, and 129 is 61.5.

Step-by-step explanation:

First, rearrange the data set in order.

38, 42, 77, 47, 74, 51, 48, 41, 82, 72, 74, 129

38, 41, 42, 47, 48, 51, 72, 74, 74, 77, 82, 129

Identify how many numbers are in the set. This will make it easier to infer the median.

Counting will show that this is a 12 number data set.

To find the median:

If there are an ODD amount of numbers in a data set, take the middle number. That is your median.

If there are an EVEN amount of numbers in a data set, take the middle two numbers, add them, then divide that by 2. That is your median.

Knowing this, take your middle two numbers, 51 and 72, and add them and divide by 2.

51 + 72 = 123

123/2 = 61.5

The median of this data set is 61.5.
