Answer:

m = 7.1

Step-by-step explanation:

3 (m -5) + 8 = 7 -1/2 (4m - 11)

So, what I did first was distribute the values in the parenthesis to get,

3m - 15 + 8 = 7 -2m -5.5

Now that we have the parenthesis taken care of we can do the simpler math,

3m - 23 = 7 -2m - 5.5

I just added the 15 and 8, so now I move the -5.5 to the opposite side by adding.

3m - 23 = 7 -2m -5.5

<u>        +5.5             +5.5</u>

3m - 28.5 = 7 - 2m

Here we can do the same with the -2m.

3m - 28.5 = 7 - 2m

<u>+2m                 +2m</u>

5m - 28.5 = 7

To get rid of the -28.5 I added it to the 7 getting an answer of,

5m - 28.5 = 7

<u>      + 28.5    +28.5</u>

5m = 35.5

Finally, divide 5m and 35.5 both by 5.

5m/5 = m

35.5/5 = 7.1

Answer: m=7.1

Sorry it's really long, but I hope this helps! Have a great day!

Find the value of x<br> a. 6<br> b. 12<br> c. 4<br> d. 10
Ede4ka [16]

Answer:

x=4

Step-by-step explanation:

Midpoint Theorem: The line joining the midpoints of two sides of the triangle is half of the length of the third side and parallel to it.

From the given figure we can see that BE is the line segment joining midpoints of two sides of the triangle. This means that

BE=\frac{1}{2} CD        [ By midpoint theorem]

Substituting values of the lengths of BE and CD

x+2=\frac{1}{2}\times 12

Simplifying and solving for x.

x+2=6

Subtracting both sides by 2

x+2-2=6-2

x=4

∴ x=4

Help that one side is 2x-2
bogdanovich [222]

Answer: x = 2/3

Step-by-step explanation:

<em>Add all sides.</em>

2x-2 + 2x - 2 + x + x =

6x - 4

<em>Put " = 0 "</em>

6x-4 = 0

Add 4 to both sides.

6x-4    =  0

   +4    = +4

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

6x=4

You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!

<em></em>

<em>NOW DIVIDE 6 FROM BOTH SIDES</em>

6x = 4

/6      /6

-----------

x= 4/6

<em>SIMPLIFY / REDUCE FRACTION</em>

4/6 divided by 2 = 2/3

2/3 is the answer !

2.5 + 3(5-2.1p) = -13.37
EastWind [94]

Answer:

2.5 + 3(5-2.1p) = -13.37

2.5+15-6.3p=-13.37

17.5-6.3p=-13.37

-6.3p=-30.87

p=4.9

hope this helps

have a good day :)
