W=Y(b+A) , for b Solve the equation for the specified variable which is b

arsen [322]

Answer:

$b=\dfrac{W}{Y}-A$

Step-by-step explanation:

As with any "solve for ..." problem, you undo what is done to the variable of interest. Here, what is done is ...

A is added
the sum is multiplied by Y

You "undo" these operations in reverse order (from the bottom of the list up). To undo multiplication, you multiply by the reciprocal:

$W\dfrac{1}{Y}=Y(b+A)\dfrac{1}{Y}=b+A$

To undo the addition of A, add the opposite of A:

$\dfrac{W}{Y}-A=b+A-A\\\\b=\dfrac{W}{Y}-A$

Vinil7 [7]

Solution:

Array is arrangement of numbers in terms of rows and columns either by rectangles or squares.

So,if an array has 32 squares

The possible arrangements are

32 = 8× 4 or 4× 8

= 16×2 or 2×16

= 1 ×32 or 32 ×1

Here first entry denotes number of rows and second entry denotes number of columns.

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

Dont forget to make this the brainliest answer to help those in need. also add a 5 star and a heart. thanks for the support hope it helped. have a nice day
