Math:

Step 1: Simplify both sides of the equation. Simply steps provided.

15−1/6n=1/6n−1

15+−1/6n=1/6n+−1

−1/6n+15=1/6n−1

Step 2: Subtract 1/6n from both sides.

−1/6n+15−1/6n=1/6n−1−1/6n

−1/3n+15=−1

Step 3: Subtract 15 from both sides.

-1/3n = -16

Step 4: Multiply both sides by -3 -1/3 by 16.

Your answer is:
n = 48

15-1/6n=1/6n-1
First, lets multiply both sides by 6 so that n is a whole number:
90-n=n-6
now you group like terms on each side, to do this you add n to each side and add 6 as well so it becomes:
96=2n
Now divide both sides by 2 so you have 'n' on one side and it is:
48=n

Hope this helps :)

30% of Number A is the same as 40% of Number B.

Goryan [66]

30% of number A means

$\dfrac{30A}{100}=\dfrac{3A}{10}$

similarly, 40% of number B means

$\dfrac{40B}{100}=\dfrac{2B}{5}$

These must be equal, so we have

$\dfrac{3A}{10}=\dfrac{2B}{5}$

Multiply both sides by 10 to get

$3A=4B \iff A=\dfrac{4B}{3}$

So, you can choose any number for A, and then you multiply it by 4/3 to get B. There are infinitely many solutions to this equation.

There are 6 yellow hexagons 2 red trapezoids and 9 green triangles how many flowers could you make if they were changed 30 yello

Zinaida [17]

Answer:

<h3>a) 5 flowers</h3><h3>b) Trapezoid</h3>

Step-by-step explanation:

For one flower, the following shapes are used;

6 yellow hexagons, 2 red trapezoids and 9 green triangles

If we are given 30 yellow hexagons 50 red trapezoids and 60 green triangles, to get the number of flowers we can make, we will find the greatest common factor of 30, 50 and 60

30 = 6*5

50 = (2*5)+40

60 = (9*5)+15

We can see that 5 is common to all the factors. This means that we can make 5 flowers if they were changed to 30 yellow hexagons 50 red trapezoids and 60 green triangles.

Since there are 40 trapezoids left and 15 green triangles left, hence the shape that would have n as left over most is trapezoid (40 left over)
