Answer:

4x -5y =11 eqn 1

8x-5y =27 eqn 2

then you subtract equation 1 from equation 2

4x=16

then you divide both side by 4

x = 4

put x=4 in eqn 1

4x-5y =11

4(4)-5y =11

16-5y =11

16-11=5y

5=5y

divide both side by 5

y = 1

:y=1,x=4

Answer:

x=4, y=1

Step-by-step explanation:

<u><em>Solve for X:</em></u>

Multiply first equation by -1:

-4x+5y=-11

Subtract they Ys:

-4x+5y=-11

<u>-</u><u>8x-5y=27</u>

4x=16

Divide by four:

x=4

<u><em>Solve for Y:</em></u>

Since we already have x, we only need to use one equation:

4(4)-5y=11

Simplify parenthesis by distribution:

16-5y=11

Subtract 16 from both sides:

-5y=-5

Divide both sides by -5:

y=1

<em><u>Check:</u></em>

4(4)-5(1)=11

16-5=11

11=11

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

8(4)-5(1)=27

32-5=27

27=27

i hope this helps u pls give brainliest and a thx ;)

Trava [24]

Answer:

Option A.

Step-by-step explanation:

From the first dot plot the given data set for week 1 is

62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 89, 89

Divide the data in 4 equal parts.

(62, 68, 68, 68, 69), (70, 70, 72, 72, 72), (75, 75, 76, 78, 78), (80, 80, 80, 89, 89)

Range=Maximum-Minimum=89-62=27

Median=\frac{72+75}{2}=73.5

Mean=\frac{\sum x}{n}=\frac{1491}{20}=74.55

From the second dot plot the given data set for week 2 is

62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 85, 86, 86, 86, 88, 88, 88, 88, 89, 89, 89, 89

Divide the data in 4 equal parts.

(62, 68, 68, 68, 69, 70, 70), 72, (72, 72, 75, 75, 76, 78, 78), (80, 80, 80, 85, 86, 86, 86), 88, (88, 88, 88, 89, 89, 89, 89)

Range=Maximum-Minimum=89-62=27

Median=\frac{78+80}{2}=79

Mean=\frac{\sum x}{n}=\frac{2364}{30}=78.8

The range for Week 1 is equal to the range for Week 2.

The median for Week 2 is more than the median for Week 1.

The mean for Week 2 is more than the mean for Week 1.

Therefore, the correct option is A.
