Answer:

(1,6)

Step-by-step explanation:

To solve by substitution, rearrange -x+y=5 to y=x+5 and substitute it into 4x+y=10.

4x + (x+5) = 10

4x+x+5=10

5x+5=10

5x=5

x=1

Now substitute x = 1 back in to find y.

y= (1) + 5

y=6

Solution is (1,6)

Verify substituting both values into each equation in to verify true.

-x+y=5

-(1)+6 = 5

-1+6=5

5=5 True

4(1)+6=10

4+6=10

10=10 True

Use the data set shown below to complete the sentence 3,3,4,5,5,9 the mean the median
lorasvet [3.4K]

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ Mean = 4.8  Median = 4.5

The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:

3 + 3 + 4 + 5 + 5 + 9 = 29

29 ÷ 6 = 4.8

To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:

4 + 5 = 9

9 ÷ 2 = 4.5
