Answer:
The correct answer is,
[tex]x = 18[/tex]
Answer:
x = 18
Step-by-step explanation:
So first you want to get rid of the fractions, which are 1/2 and 1/3. To do this you can multiply both sides of the equation by 6, so you would get:
3x - 42 = 2(x - 12).
Next, on the right side of the equation you can distribute the 2.
3x - 42 = 2x - 24
You want to get all the x variables on one side so you can subtract 2x from both sides.
x - 42 = -24
And finally you add 42 to both sides
x = 18

HELP HELP HELP IM GONNA FAIL
Answer:
[tex]y=\frac{9\sqrt{3} }{2}[/tex] or 7.79 x= 9/2 or 4.5
explanation:
This is a special right triangle; a 90-60-30 triangle.
The side labelled y = a, side labelled x is equal to [tex]a\sqrt{3}[/tex], and the hypotenuse equals 2a.
First solve for a. [tex]9\sqrt{3}=2a[/tex] [tex]a=\frac{9\sqrt{3} }{2} =y[/tex] and that gives you y.
Then use a to find x. [tex]a\sqrt{3} =x[/tex] so [tex]\frac{9\sqrt{3} }{2} *\sqrt{3} = 9/2=4.5[/tex]

What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
We have to given that;
The expression is,
⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)
Now, We can subtract the expression as;
⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)
⇒ 12x² - 11y² - 13x - 5x² + 14y² + 9x
⇒ 12x² - 5x² - 11y² + 14y² - 13x + 9x
⇒ 7x² + 3y² - 4x
Thus, The value of the difference of the polynomials are,
⇒ 7x² + 3y² - 4x

Math help please right answer
Answer:
135°
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 720
Two of the angles are right (has 90°)
so 4x + 180 = 720 subtract 180 from both sides
4x = 540 divide both sides by 4
x = 135°
What is the solution to the equation 6- t = 2t
Answer:
t=2
Step-by-step explanation:
Literally just move all the common like terms onto one side.
6=3t
It is usually prefered to have the variables on the left and the coefficients on the right so you would flip your equation.
3t=6
Then you get t by itself by dividing by 3. Your final answer should be 2.

Mrs. Sanders can clean the windows of her house in
3 hours. Her daughter can clean the windows in 6 hours.
How long will it take them to clean the windows if they
work together?
9514 1404 393
Answer:
2 hours
Step-by-step explanation:
Mrs. Sanders cleans 1/3 of the windows per hour. Her daughter cleans 1/6 of the windows per hour. Working together, they clean 1/3 +1/6 = 1/2 of the windows per hour.
It will take them 2 hours to finish when they work together.

3. Given the function f(x)=x^2+4x-12:
a. Identify the zeros using factorization.
Answer:
x = -6, 2
Step-by-step explanation:
A zero is the x-value of a point on the x-axis that the graph intersects. Knowing this, we can set the function itself to 0 to find the zeros.
1) Set the function to 0.
[tex]x^2+4x-12 = 0[/tex]
2) Factor out the polynomial. Ask yourself, what are two numbers that have a product of -12 and add up to 4? (In this case, it's 6 and -2.)
[tex]x^2+4x-12 = 0\\(x+6)(x-2) = 0[/tex]
3) Look at the answer from the last step. What do the x's have to equal in order for equation to equal 0? They have to be -6 and 2. Therefore, those are the zeros.
