y=5

Step-by-step explanation:

x=28-6y

2x-3y=-19

Bens teacher ask him to write a three- digit number that uses the digit 3 once and the digit 6 twice. The value of one 6 needs t
nata0808 [166]
We have three numbers to arrange so that 6 is 1/10 of the value of the other six.

Since position tells us whether we're talking about single, tens, hundreds, thousands (e.g. 25 is two times 10 plus five times 1) we know that the two sixes must be next to each other.

This leaves us with two options.
663 or 366.

In each of these cases the second 6 in the number is one tenth of the first 6.

If we look at the only other option: 636 we see that the second 6 is one hundredth of the value of the first 6.

What is the factorization of the expression below?
olchik [2.2K]

Answer: D. (x-6)(x-6)

Step-by-step explanation:

We have the following trinomial, which is also known as perfect square trinomial, because the first and the third term are squares:

x^{2}-12x+36  (1)

First term:x^{2}  

Third term:36=6^{2}  

If we factorize this expression we have:

(x-6)(x-6)=x^{2}-6x-6x+36=x^{2}-12x+36

As we can see, the trinomial (1) has two factors:

(x-6) and (x-6)

Therefore, the correct option is D.

IrinaK [193]

Answer:

Option (b) is correct.

The expression is equivalent, but the   term is not completely factored.

Step-by-step explanation:

Given :  a student factors  to

We have to choose the correct statement  about   from the given options.

Given   is factored to

Consider    

Using algebraic identity,

comparing  and b = 4, we have,

Thus, the factorization is equivalent but we can simplify it further also, as

Using algebraic identity,

Thus,

Can be written as

Thus, the expression is equivalent, but the   term is not completely factored.

Option (b) is correct.

Please help! Correct answer only! This assignment is due today.
Bas_tet [7]

Step-by-step explanation:

Well they made 19 clay, where 12 were vases. That means 7 were not vases. She randomly chooses 16 clay objects, which then also means 3 were left behind. so if the vases are  12/19, which is approximately 63%, then 63% of the objects are vases. Makes sense, right? Well now we need to multiply that by the initial 11 in the question. After all of this work..

Answer: 6.9474 or 6.94736.

Please mark as Brainliest.
