2.8m + 0.8


-2.8m + 0.8

Answers

Answer 1

Answer:

m = 0.28571428571

or 0.29(to the nearest tenth)

Step-by-step explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

-16.8m = -4.8 =

m = 0.28 or 0.29

i need to know where to graph it too

Answers

Step-by-step explanation:

y=2x+3

y=3x+3

(Use the elimination method)

y=2x+3(-3) = -6x-9

y=3x+3(2) = 6x+6

(subtract the new equations)

y= -3

(Now find X)

(plug in y in any equation and solve)

y=2x+3

(-3)=2x+3

0= 2x X= 0

or you can just graph the lines go to three on the Y axis put a point go up the y-axis two and over 1 and plot another point.

y=180+11-6x

Step-by-step explanation:

Let D =Devaughn's age

S= Sydney's age

So D+S=64

D=S+12

Now

D+S=64⇒D=64−S

and so

S+12=64−S 2S=52

S=26

Therefore

D=S+12

D=38

Which of the following is the correct five-number summary?

22, 24, 26, 28, 29
23, 24.5, 26, 28, 29
22, 24, 27, 28, 30
22, 24.5, 26, 28, 30

Answers

Given:

The data values are 22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30.

To find:

The five-number summary.

Solution:

We have,

22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26, 26, 26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30

Divide the data values on 2 equal parts.

(22, 23, 23, 24, 24, 24, 25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28, 28, 28, 28, 29, 29, 30)

Divide each parentheses in two equal parts.

(22, 23, 23, 24, 24, 24), (25, 25, 25, 25, 26, 26), 26, (26, 26, 27, 27, 27, 28), (28, 28, 28, 29, 29, 30)

Now,

Minimum value = 22

[tex]Q_1=\dfrac{24+25}{2}=24.5[/tex]

Median = 26

[tex]Q_2=\dfrac{28+28}{2}=28[/tex]

Maximum value = 30

So, the five number summary is 22, 24.5, 26, 28, 30.

Therefore, the correct option is D.

Expo Milano 2015 was visited by 22.2 million people. It is expected that Expo 2020 Dubai will
be visited by 25 million people. Find the percent of change.

Answers

Answer:

12.6% is the percent of change.

Step-by-step explanation:

As Expo Milano 2015 was visited by 22.2 million people.

And it is expected that Expo 2020 Dubai will  be visited by 25 million people.

so

25 - 22.2 = 2.8 million people

so dividing the 2.8 by 22.2 would give us the percentage of increase.

2.8/22.2 = 0.126 which is = 12.6%

Therefore, 12,6%  is the percent of change.

Find the length of MN.

*LOOK AT PICTURE*

Answers

Answer:

MN = 10

Step-by-step explanation:

There is a scale factor of 2 [This means that the lengths of triangle ∆MPN are exactly 2 times larger than ∆SRQ], so 5 × 2 = 10.

Notice that each corresponding line is marked by a black mark perpendicular to the side. Since 2 corresponds to 4, and 3 corresponds to 6, 5 must correspond to 10. These triangles are similar as indicated by the marks so there is just a size difference. Because these two triangles are similar, the sides must be proportional.

∆MPN ~ ∆SRQ.

It can also be thought of as completing a set of proportional fractions:

4/2 = 6/3 = ?/5

4/2 = 2 → 6/3 = 2 → ?/5 = 2.

?/5 = 2, ? = 5 × 2 = 10.
