Answer:

3.5 kg

Step-by-step explanation:

if you convert 6 Ib and 3.5 kg to grams you get

6 Ib = 2721.6 grams

3.5 kg = 3500 grams

Since 3.5 kg has more grams lost from the diet.

Solve the system of equations and choose the correct ordered pair. 3x-2y=12 and 6x+3y=21
NemiM [27]

Answer:

Solution ( \frac{26}{7} ,  \frac{-3}{7})

Step-by-step explanation:

Given  :  3x - 2y = 12 and 6x + 3y = 21.

To find : Solve the system of equations and choose the correct ordered pair.

Solution : We have given

3x - 2y = 12 -------(1)

6x + 3y = 21-------(2)

Multiplying the equation(1) by 2 , it become.

6x - 4y = 24 .

Now subtract it from equation (2).

6x + 3y = 21

(-)6x - (+)4y = (-)24 .

____________

0 + 7y = -3.

On dividing both sides by 7.

y = \frac{-3}{7}.

Plug the y = \frac{-3}{7} in equation 2 .

 6x  + 3*\frac{-3}{7} = 21

6x + \frac{-9}{7}  = 21.

On multiplying both sides by 7

42x  -9 = 21 *7 .

42x  -9 = 147 .

On adding both sides by 9

42x = 147 + 9 .

42x = 156.

On dividing both sides by 42.

x = \frac{156}{42}.

x = \frac{26}{7}.

Therefore, Solution ( \frac{26}{7} ,  \frac{-3}{7})

I dont understand how to put questions together.​
lorasvet [3.4K]

Answer:

D

Step-by-step explanation:

You are subtracting two functions to get the profit, the formula is p(x)=r(x)-c(x). You know what two of those functions are equivalent to so plug it in to get

p(x)=11x-(6x+20)

to solve you must first get rid of the parentheses by distributing the negative.

p(x)=11x-6x-20

then, combine like terms (both x's)

p(x)=5x-20

That is your final answer.

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.
