Answer:

6(9r-7)

Step-by-step explanation:

54r–42

Both 54 and 43 can be divided by 6

54/6 =9  and 42/6 =7

6*9r - 6*7

Factor out the 6

6(9r-7)

Answer:

6(9r - 7)

Step-by-step explanation:

Think:  what's the largest factor shared by 54 and 42?

54 = 6·9 and 42 = 6·7

That largest common factor is 6.

Then 54r - 42 = 6(9r - 7)

Answer:

(2,4) is a solution to this system of equations

Step-by-step explanation:

Given system of equation are

y=2x \hfill (1)

y=\frac{-1}{2}x+5\hfill (2)

To find the solution of the given system of equations

To Check that (2,4) is a solution to this system or not

Solving equations (1) and (2)

From equation (1) and y=2x

Now substitute y=2x is equation (2)

2x=\frac{-1}{2}x+5

\frac{-1}{5}x+5-2x=0

5-\frac{x}{2}-2x=0

5-\frac{x+4x}{2}=0

5-\frac{5x}{2}=0

\frac{10-5x}{2}=0

10-5x=0

-5x=-10

x=\frac{10}{5}

Substitute x=2 in equation (1)

y=2x

y=2(2)

Therefore y=4

Therefore the solution is (2,4)

Therefore (2,4) is a solution to the system of equations.

Help no troll answer plz

Answer:

Step-by-step explanation:

<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>

<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!

Wavelength (lambda) = Velocity (v) ÷ Frequency ( sec^{-1} or Hz )

f = v / (lambda)

f = 3 / 2 = <em>1.5 (Hz)</em>

<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>

Only the circled ones

2.

M must be (0,0) since it coincides with the origin
R must be (a+b, √(a²-b²)).
The x-coordinate is b from A translated to the right by a.
The y-coordinate is the same as A.

(I think the square root is there to confuse you).

3.

R(0,0)
C(a,b) (same x as T, same Y as E)

5.

Not sure how to prove that.

what is the correct first step in finding the area of the base of a cylinder with a volume of 140 pi cubic meters and a height o
maxonik [38]
The volume of the cylinder by definition is given by:
 V = Ab * h
 Where,
 Ab: base area
 h: height
 Substituting values we have:
 140 = Ab * 12
 To find the area, the first step is:
 Pass the 12 dividing.
 Answer:
 
the correct first step in finding the area of the base of a cylinder is:
 
Pass the 12 dividing.
