3/5 can be un-simplified into a number of different fractions. 3/5, 6/10, 12/20, etc.

The way we figure this out is by multiplying each side of the fraction by an integer. Say 2. So if the fraction is 3/4, times the top and bottom by 2 making it 6/8

dedylja [7]

Step-by-step explanation:

J = 2b

M = J + 7

M = 21

J = 21 - 7

J = 14

B = 7

<em>Equation:</em>

If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.

Prove the divisibility of the following numbers:
ratelena [41]

Make use of prime factorizations:

16^5+2^{15}=(2^4)^5+2^{15}=2^{20}+2^{15}

Both terms have a common factor of 2^{15}:

16^5+2^{15}=2^{15}\left(2^5+1\right)=2^{15}\cdot33

- - -

The second one is not true! We can write

15^7+5^{13}=(3\cdot5)^7+5^{13}=3^7\cdot5^7+5^{13}

Both terms have a common factor of 5^7:

15^7+5^{13}=5^7\left(3^7+5^6\right)

Since 30=5\cdot6, and 5\mid5^7, we'd still have to show that 5^6(3^7+5^6) is a multiple of 6. This is impossible, because 6=3\cdot2 and there is no multiple of 2 that can be factored out.

Pls help me with this i will give crown
valkas [14]

Answer:

C

Step-by-step explanation:

The easiest way to solve this would be to find the difference between the numbers. We can do -3-(-9) to find the difference of 6. We can then make sure this is true for the rest of the sequence by adding 6 to each number.

-9+6=-3

-3+6=3

3+6=9

9+6=15

Now that we've verified that this is true, we know the answer is C
