Answer:
The answer is x= -4/3
Step-by-step explanation:
3(x-4)=12x
=3x-12=12x
=3x-3x-12=12x-3x
-12=9x
To find x divide both sides by 9.
-12÷9=9x÷9
-4/3=x

Store A sells 3 t-shirts for $25. Store B sells the same t-shirts: 5 for $40. Which store has the better deal?
Show your work supporting your answer.
Answer:
Store B
Step-by-step explanation:
To figure out which store has the better deal, we need to figure out the price per unit. We can do this by dividing the price by the number of the shirts. Store A sells their t-shirts for 8.33 or 8 1/3 dollars per shirt, while Store B sells their shirts for 8 dollars a shirt. 8 < 8 1/3, therefore Store B has the better deal.
Answer:
B.
Step-by-step explanation:
If you do 3/25=5/x. You would get $41.6. Another way to show it is to divide 25/3 and 40/5, which would give us $8.3 and $8.

The lowest elevation in Lammefjord, Denmark, is 23 feet below sea level. The elevation of the Sea of Galilee in Israel is about 30 times lower than the elevation of Lammefjord. What is the approximate elevation of the Sae of Galillee written as an integer?
Answer:
[tex]Sea\ of\ Galilee = -690ft[/tex]
Step-by-step explanation:
Given
[tex]Lowest\ Elevation = 23ft[/tex] below sea level
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
Required
Determine the elevation of the Sea of Galilee
We have that the lowest elevation in Lammefjord is:
[tex]Lowest\ Elevation = -23ft[/tex]
It is negative because, the elevation is below sea level.
Calculating the elevation of Sea of Galilee, we have:
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
[tex]Sea\ of\ Galilee = 30 * -23ft[/tex]
[tex]Sea\ of\ Galilee = -690ft[/tex]
Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level

If you are trying to simplify the expression, the answer is -14x^2+8x-37
Step-by-step explanation:
First, keep removing the parentheses.
(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)
Next, try expanding the expression.
3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6
3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6
3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2

i dont understand the question
Step-by-step explanation:
The point (1,0) lies on the graph of
P(x) = x^4 - 2x^3 - x+2
A. True
B. False
Answer:
The given statement is true.
Step-by-step explanation:
Given function is:
[tex]P(x) = x^4 - 2x^3 - x+2[/tex]
And the given point is:
(1,0)
In an ordered pair, the first element is the input and second is the output. If we plug in the input to the function and get the respective output then the point lies on the graph of function.
For (1,0) we will put x = 1 in function and check whether we get 0 as output
[tex]P(x) = (1)^4 - 2(1)^3 - 1+2\\= 1-2(1)-1+2\\= 1-2-1+2\\=0[/tex]
Hence,
The given statement is true.

Question 4 of 10
Which of the following is equal to divide 9•4
Answer:
36 ÷ 9= 4
Step-by-step explanation:
9 x 4= 36
The division equation for this is 36 ÷ 9= 4
The product of the expression 9 and 4 is 36.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Give that we have to multiply 9 with 4.
This means that 9 has to be added repeatedly up to 4 times or 4 has to be added repeatedly up to 9 times.
In both cases, the product must be the same.
9 multiplied by 4 = 9 + 9 + 9 + 9
Which is also equal to,
4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4
= 36
Hence the product is 36.

what is the sum of three consecutive even numbers is 30?
Answer:
here:
you can make an equation
x + ( x + 2) + (x + 4) = 30
then by combining like items you get
3x + 6 = 30
then solve
3x = 30 - 6 ; then 3x = 24 , and x = 8
so the three numbers are 8 ; 10 and 12.
What is the remainder when
f(x) = 2x4 + x2 – 8x – 1 is divided
by x - 6?
Answer:
Step-by-step explanation:
x - 6 = 0
x = 6
f(x) = 2x⁴ + x² - 8x - 1
=2(6)⁴+ 6² - 8*6 - 1
= 2*1296 + 36 - 48 - 1
= 2592 + 36 - 48 - 1
= 2628 - 49
