Answer:m > 27

Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = -3

Step-by-step explanation:

3x + 9 = 12x + 36 (rewrite)

3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9

3x - 12x = 36 - 9 (collect like terms)

-9x = 36 - 9 ( substract)

-9x = 27 (divide both sides for the answer)

-9       -9

x = -3

Answer:

n+1=4(n-8)

n+1=4xn/4 x-8

n+1=4n-32

1+32=4n-n

33=3n

33/3=3n/3

11=n

Answer:

numerator

Step-by-step explanation:

it becomes the numerator because however many places over the numbers to the decimals are is the amount if its in like the 10th 100th 1000th and so on. But if there is a one or more to the left side of the decimal it becomes the whole number, so that leaves the numerator. So that is how the numerator is the answer.

I took the test :)

Answer:

-3.5

Step-by-step explanation:First you need to order the numbers so the numbers ordered would be -20,-16,-10-,10-,7,0,1,2,5,8 the median is finding the middle number in a list so you would cross of the end numbers until you are left -7 and 0 you then find the mid point of these two numbers which is -3.5 so that would be the answer.

Answer:

The median is -3.5

Step-by-step explanation:

hope this helps

-16, -20, -10, 1, -10, 5, 0 ,8 ,2 ,-7

Arrange the number in numerical order.

-20,-16,-10,-10,-7,0,1,2,5,8

There's two number is the middle which is -7 and 0 all you have to do is add them together and divide by 2.

-7+0= -7÷2=-3.5

Answer:

Scott is 6 feet tall

Step-by-step explanation:

Just basically 72 divided by 12 because 12 is one foot

Answer:

6

Step-by-step explanation:

Answer: After 6 Months Casey would have paid $450 at either gym.

Step-by-step explanation:

Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:

35x + 240 = 75x (the 1st gym with a joining fee $240 and 35 monthly equals $75 monthly)

Subtract 35x from both sides:

35x - 35x + 240 = 75x - 35x

240 = 40x

Divide by 40:

240 / 40 = 6

6 = x

So they cost the same after 6 months

35 * 6+ 240 = 75 * 6

450 = 450

And you'll be spending $450 in total.

Answer:

2+2 is 4-1 is 3 quick maths

Step-by-step explanation:

Answer:

I will give you everything angle QSR would be 128 degrees and angle QRS would be 26 degrees from those two you can figure out that angle RQS is also 26 degrees making this a isosceles triangle, meaning that even if we do not know what side QS and RS are we know that they will be equal. Hope this helped.

Answer:

37.5

Step-by-step explanation:

Answer:

wt87

Step-by-step explanation:

u = ⟨-2, 6⟩

v = ⟨3, 2⟩

w = ⟨-1, 4⟩

u + v = ⟨-2, 6⟩ + ⟨3, 2⟩

u + v = ⟨-2 + 3, 6 + 2⟩

u + v = ⟨1, 8⟩

2 (u + v) = 2 ⟨-1, 8⟩

2 (u + v) = ⟨2 • 1, 2 • 8⟩

2 (u + v) = ⟨2, 16⟩

-3 w = -3 ⟨-1, 4⟩

-3 w = ⟨-3 • (-1), -3 • 4⟩

-3 w = ⟨3, -12⟩

2 (u + v) - 3 w = 2 (u + v) + (-3 w)

2 (u + v) - 3 w = ⟨2, 16⟩ + ⟨3, -12⟩

2 (u + v) - 3 w = ⟨2 + 3, 16 + (-12)⟩

2 (u + v) - 3 w = ⟨5, 4⟩

Then the magnitude of this vector is

||2 (u + v) - 3 w|| = √(5² + 4²) = √41 ≈ 6.403

so the second choice is correct.

Answer:

B) 6.4; θ = 38.7°

Step-by-step explanation:

got it right on edge :)

Answer:

The slope is 1.

Step-by-step explanation: This answer is correct, because the rise is 2 and the run is 2 which means 2/2 and that equals 1.

x = -1

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

-1

Step-by-step explanation:

5(x+1)+5=5

Distributive property

5(x)+5(1)+5=5

5x+5+5=5

5x+10=5

    -10  -10

5x=-5

---  ---   divide both sides by 5 to get x by itself

5   5

x=-1

Answer:

h = 24 cm

Step-by-step explanation:

volume of water in the cylinder = volume of water in the rectangular base container

But ,

volume of cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

where:  is the radius and h is the height.

volume of cuboid = length x width x height

                             = l x w x h

So that;

[tex]\pi[/tex][tex]r^{2}[/tex]h = l x w x h

But, r = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, [tex]\pi[/tex] = [tex]\frac{22}{7}[/tex].

Thus,

[tex]\frac{22}{7}[/tex] x [tex](9)^{2}[/tex] x 28 = 27 x 11 x h

[tex]\frac{22}{7}[/tex] x 81 x 28 = 27 x 11 x h

7128 = 297h

h = [tex]\frac{7128}{297}[/tex]

  = 24

h = 24 cm

The depth of the water in the container is 24 cm.
