The value of x is 24 because 24-12=12
I worked it out by doing the opposite so by doing 12+12
Then the value of y is also 24 and I used the same method

Actually, If you put x=24 the answer wouldn't be 12 like the equation, but if put x=28 in the problem: 3/4 * (28-12) it WILL equal 12 just like the equation says. Same thing with y, if you put y=24 in the equation it wouldn't equal 12 like said it would. Now, using PEMDAS, x=32 we can solve the equation. 3/4 * 32-12=12.

To make short, the answer of

Equation 1:

x=28

Equation 2:

y=32

Solve for t. t + 19 = 45) it will give u 29 points if u help me!

Oksi-84 [34.3K]

Hi there!

<u><em>Answer:</em></u>

<u><em>t=26</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

First, you subtract by 19 from both sides of an equation.

$t+19-19=45-19$

Then, you subtract by the numbers from left too right.

$45-19=26$

<u><em>Final answer is t=26</em></u>

I hope this helps you!

Have a nice day! :)

What is the difference of the rational expressions below?

Stolb23 [73]

Answer: A

Step-by-step explanation:

We need to get the denominators to be same first before we can do anything to the numerator.

<em>The LCD (lowest common denominator) is </em> $3x^{3}$ <em>. To find the LCD, multiply the denominators together: </em> $x^{3}$ <em> · </em> $3x$ <em> = </em> $3x^{3$ .

Below, we are trying to get the denominators to equal the same or to $3x^{3}$ .

$\frac{3}{3} (\frac{4}{x^{3} } ) - \frac{x^{2} }{x^{2} } (\frac{2x-1}{3x} )$

$\frac{12}{3x^{3} } - \frac{2x^{3}-x^{2} }{3x^{3} }$

Now that the denominators are the same, we can subtract the numerators from each other.

$\frac{ 12 - (2x^{3} -x^{2})\\}{3x^{3} } \\$

$\frac{12-2x^{3} +x^{2} }{3x^{3} }$

Now, we can just reorganize the variables.

Answer: A or $\frac{-2x^{3} + x^{2}+12 }{3x^{3} }$

Mark bought a house in 1995 for $200,000. His house has appreciated 4 % every year since he bought it. How much is his house wor

Svetach [21]

Answer:

the worth of the house today is $392,000

Step-by-step explanation:

in 1995 --------- $200,000

and its appreciates by 4% yearly

so by 2019 the house will be

firstly we subtract 2019 from 1995 to know how many years the house has appreciated for

2019 - 1995 = 24years

therefore to get the total % the house has appreciated for we multiply the year by 4%

24 * 4% = 96%

so to get the appreciated value we multiply 96% by the initial amount of the house

96% * $200,000 = $192,000

therefore the worth of the house at present will be the initial amount plus the appreciated value

$200,000 + $192,000 = $392,000
