Let s = something

(2/3) + s = 1

Multiply both sides by 3.

2 + 3s = 3

Subtract 2 from both sides.

3s = 1

Divide both sides by 3.

3s/3 = 1/3

s = 1/3

What is the irrational number in This set: 12.89, square root of 12 and 12/144 ?

kifflom [539]

Good night,

<span>Irrational numbers are those that can't be expressed as a fraction:

12.89 can be expressed as: </span> $\frac{1289}{100}$

$\frac{12}{144}= \frac{1}{12}$

<span>The above numbers can be expressed as a fraction, then the logical answer is: </span> $\sqrt{12}$

But we will check the answer:

$\sqrt{12}= \sqrt{2^{2}*3 } =2* \sqrt{3} =3.4641016...$

As you can see we can't express that number as a fraction, so that is te correct answer.

-2x + 3y = 18. x = -y + 1

Bezzdna [24]

Answer:

D. X=-3, y=4

Step-by-step explanation:

-2x+3y=18 equation 1

x=-y+1 equation 2

-2(-y+1)+3y=18 replace x value of equation 2 into equation 1

2y-2+3y=18

5y=20

y=4

solve for x by replacing y value into either equation.

x=-y+1

x=-4+1

x=-3

Quincy claims that if 80 coats are sold, the outside temperature is likely to be about 42°

nikklg [1K]

No. Quincy should have used the trend line to find the corresponding x value when y=80.

Is the sequence geometric? if so what is the common ratio/answers 2,-4,-16,-36/

VLD [36.1K]

Answer:

We conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.

Step-by-step explanation:

Given the sequence

2, -4, -16, -36,...

A geometric sequence has a constant ratio 'r'.

Let us compute the ratio of all the adjacent terms

$\frac{-4}{2}=-2,\:\quad \frac{-16}{-4}=4,\:\quad \frac{-36}{-16}=2.25$

It is clear that the ratio is not constant.

Thus, the given sequence is not a geometric sequence.

Therefore, we conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.
