3y means *three times y.* So it can be written as 3y or 3•y or written out three times the variable y.

How to go from sum of products to product of sums?
irina [24]

Multiplication gives us distribution over the products, so

 

(a′+b+d′) (a′+b+c′+f′) = a′ (a′+b+c′+f′) + b (a′+b+c′+f′) + d′ (a′+b+c′+f′)

 

And then you can then distribute again each of the factors on the right.

Then you should simplify in any given number of ways. To take as an example, you have a′b and ba′, and since a′b + a′b = a′b + a′b = a′b, you can just drop one of them. Since bb = b, you can rewrite bb as b and etc.

 

So in the end part we should arrive at a sum of products. Then you can just invert. For example, if at the end you had:

p′ = a′b + bc′ + d′f ′+ a′f′

 

Then we would have

p = p′′ = (a′b + bc′ + d′f′ + a′f′)′ = (a′b)′⋅(bc′)′⋅(d′f′)′⋅(a′f′)′

 

Then applying De Morgan's laws to each of the factors, e.g., (a′b)′ = a+b′, so we would have

p = (a+b′)⋅(b′+c)⋅(d+f)⋅(a+f)

which is a product of sums.

The ratio of the number of Miki's stickers to the number of Ken's
Lera25 [3.4K]

Answer:

Miki had 288 stickers and Ken had 252 stickers.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

Miki has x stickers.

Ken has y stickers.

The ratio of the number of Miki's stickers to the number of Ken's stickers was 8:7.

This means that \frac{x}{y} = \frac{8}{7}, that is: 7x = 8y, or x = \frac{8y}{7}

After Miki gave Ken 18 of her stickers, they had the same number of stickers.

This means that:

x - 18 = y + 18

x - y = 36

Since x = \frac{8y}{7}

\frac{8y}{7} - y = 36

\frac{8y}{7} - \frac{7y}{7} = 36

\frac{y}{7} = 36

y = 36*7 = 252

And

x - y = 36

x = 36 + y = 36 + 252 = 288

Miki had 288 stickers and Ken had 252 stickers.
