Tmes -3 each times so next 2 numbers are -243 then 729

Answer:

-243 and 729.

Step-by-step explanation:

We have been given a pattern –3, 9, –27, 81, . . . We are asked to find the next two numbers of our given pattern.

We can see that our given pattern is in form of geometric sequence. We need to find the common ratio of our given sequence by dividing any term of sequence by its previous term.

r=\frac{9}{-3}=-\frac{9}{3}=-3.

So the next number of our given term would be 81\times -3=-243.

The next number would be  -243\times -3=729.

Therefore, the next two numbers of our given sequence are -243 and 729.

25 is 36% of what number
ch4aika [34]

Answer:

x = 69.44

Step-by-step explanation:

We have, 36% × x = 25

or, 36/100 × x = 25

Multiplying both sides by 100 and dividing both sides by 36,

we have x = 25 × 100/36

x = 69.44

If you are using a calculator, simply enter 25×100÷36, which will give you the answer.

The (greatest, least) of the common factors of 2 or more numbers is the (greatest, least) common factor of the numbers.
Liula [17]

Answer:

The greatest of the common factors of 2 or more numbers is the greatest common factor of the numbers.

Step-by-step explanation:

As we know that

The greatest common factor of two or more whole numbers is the largest whole number that divides evenly into each of the numbers.

Thus, the greatest of the common factors of 2 or more numbers is the greatest common factor of the numbers.

For example, lets find the greatest common factor of 36 and 54.

The possible factors of 36 are:

                                                   1, 2, 3, 4, 6, 9, 12, 18, and 36.

The possible factors of 54 are:

                                                   1, 2, 3, 6, 9, 18, 27, and 54.

The common factors of 36 and 54 are:

                                                   1, 2, 3, 6, 9, 18

So, from the common factors, it is easy to figure out that 18 is the greatest common factor.

6x-4y=-14 <br>-3x-3y=12<br><br>with the elimination method
Vanyuwa [196]
6x-4y=-14
2(-3x-3y=12)

6x-4y=-14
-6x-6y=24

-10y=10
Divide both sides by 10
-1y=1 divide by -1
y=-1

6x-4(-1)=-14
6x+4=-14
-4 -4
6x=-18
Divide both sides by 6
x=-3

Solve the equation 7=4s+19
lyudmila [28]

Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract 19 from both sides

7 (-19) = 4s + 19 (-19)

7 - 19 = 4s

-12 = 4s

Isolate the s. Divide 4 from both sides

-12/4 = 4s/4

s = -12/4

s = -3

-3 is your answer for s

hope this helps
