Answer:

The answers are:

(x,y,z)=

(5,1,-2)

(1,-2,5)

(-2,5,1)

(5,-2,1)

(-2,1,5)

(1,5,-2)

Step-by-step explanation:

In order to determine the answer, we have to express the final number into a addition.

The number 700070.07 may be written by:

700000+70+0.07

Then, we can express every number into a scientific notation,that is, at the form:

$a*10^b$

700000

a=7

b=5

$7*10^5$

a=7

b=1

$7*10^1$

0.07

a=7

b=-2

$7*10^-^2$

So, in this case, we have three numbers: 5, 1, -2. The set of values are the combination of these numbers, in total 6 set of numbers.

Finally, the possible set of values for x, y, z are:

(5,1,-2)

(1,-2,5)

(-2,5,1)

(5,-2,1)

(-2,1,5)

(1,5,-2)

Answer:

(x,y,z)=(5,1,-2) or (5,-2,1) or (1,5,-2) or (1,-2,5) or (-2,5,1) or (-2,1,5)

Step-by-step explanation:

700070.07 = 700000 + 70 + 0.07

700000 = 7*10^5

70 =7*10^1

0.07=7*10^-2

Last year, Deshaun had $20,000 to invest. He invested some of it in an account that paid 9% simple interest per year, and he inv

dezoksy [38]

Answer:

the amount Deshaun invested in an account that paid 9% interest = $9,000

the amount Deshaun invested in an account that paid 5% interest = $11,000

Step-by-step explanation:

Let x = the amount Deshaun invested in an account that paid 9% interest

Let y = the amount Deshaun invested in an account that paid 5% interest.

Thus;

x + y = 20,000 - - - - (eq 1)

Now, After one year, he received a total of $1440 in interest. Thus;

0.09x + 0.05y = 1440

Multiply each term by 100 to give;

9x + 5y = 144000 ---- (eq 2)

Making x the subject in equation 1,we have;

x = 20,000 - y

Putting 20,000 - y for x in eq 2,we have;

9(20,000 - y) + 5y = 1440

180000 - 9y + 5y = 144000

180000 - 4y = 144000

180000 - 144000 = 4y

36000 = 4y

Divide both sides by 4 to give;

y = 36000/4

y = $9,000

x = 20,000 - 9000

x = $11,000

Tory is solving the equation shown correctly in her notebook, but the paper gets smudged, and she cannot read the last few lines

elena55 [62]

This question is incomplete because the options are missing. Here are the options:

A. - 4 = 5x

B. -4 = x

C. -4 + x = 0

D. -4 + 5x = 0

The correct next line of the solution is A. -4 = 5x

An equation is:

A mathematical expression that represents mathematical equality between two expressions.

It has two expressions and is separated by the equal sign, called members.

It has known elements and unknown or unknown data represented with letters like x

According to the above, it can be inferred that the correct answer is option A. because it expresses the correct values according to the operations that have been carried out in the previous lines.
