4m+30=6m can you please answer this question

Mathematics
2 answers:
Arisa [49]3 years ago

Answer:

15

Step-by-step explanation:

1) let’s bring all the like terms(terms that have the same variable) together so we can combine them

Bring”6m” to the left(doing this will make 6m negative) And bring 30 to the right(doing this will make 30 negative)

*they switch spots basically*

So

4m-6m=-30

-2m=-30

Divide both sides by -2

M=15

Hope this helps!

Answer:

M = 15

Step-by-step explanation:

To get m alone you need to subtract 4m by both sides

4m - 4m + 30 = 6m -4m

30 = 2m

Now last part is to divide 2 by both sides

30/2 = 2m/2

M = 15

Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.
olchik [2.2K]

Answer:

A=28.1\ cm^2

Step-by-step explanation:

The area of a circular sector with a central angle θ and radius r is given by:

\displaystyle A=\frac{1}{2}r^2 \theta

<em>Note</em>: The angle must be in radians.

We need to find both the radius and the angle in radians.

Diameter = 9.6 cm

Radius r=Diameter/2=4.8 cm

Angle in radians= Angle in degrees*π / 180

θ = 140*π / 180 = 2.4435 rad

Now we calculate the area:

\displaystyle A=\frac{1}{2}(4.8)^2 2.4435

\boxed{A=28.1\ cm^2}

Does the point (5, 8) satisfy the inequality 2x + y &gt; 18?​
Anarel [89]

Answer:

The answer is...... NO

Step-by-step explanation:

Step 1: Plug in your values in the x and y cordinates.

2(5) + 8 > 18

Step 2: Solve

Then you multiply 2 and 5 and get 10.

SO then your equation should look like this:

10 + 8 > 18

The answer to the question is no because in order for this to work it would need to be the greater than or equal to sign, which looks like this ≥.

Hope this helps and have a great day! :)
