Answer:
Change 28% to a decimal by moving the decimal point 2 places to the left:
28% = 0.28
Write the question as an equation to get:
56 = 0.28x
Now to solve for x, divide both sides by 0.28:
x = 56 / 0.28
x = 200
The unknown number is 200.
Step-by-step explanation:
Step-by-step explanation:
28% of an unknown number is (x)=56
28/100 of x=56
x=56×100/28=200If x= -4 and y=-8, which expression would have a negative value?
A: x+y
B: x-y
C: x*y
D: x/y
Step-by-step explanation:
x + y will have negative value as
x + y = -4 + (-8) = - 4 - 8 = - 12
Answer:
A
Step-by-step explanation:
They are both negative so you will keep the negative sign when you add.
hi so I have a question for math.. the math problem is: The coordinates of the vertices of a quadrilateral are P(1,2), R (1,4), S (3,4), and T (4,2).

What is the additive inverse of -10?
Answer:
The inverse with respect to addition; the opposite. The additive inverse of 12 is −12. The definition of an additive inverse is the number needed to bring a negative number to zero. An example of an additive inverse is the number 30 when added to -30. So the additive inverse of -10 is 10
Step-by-step explanation:
Answer: 10
Step-by-step explanation:
To find the additive inverse of a number, all we should do is change its sign. Thus, the additive inverse of a positive number is a negative number, and the additive inverse of a negative number is a positive one. So the additive inverse of -10, which is negative, is positive 10, or just 10.

The equation of the parabola that represents the given graph is y = 3x².
The correct option is B.
What is a parabola?A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.
If the vertex of the parabola is at (0, 0), then the equation of the parabola has the form:
y = a x²
where "a" is a constant that determines the shape of the parabola. We need to find the value of "a" using the fact that the parabola passes through the point (1, 3).
Plugging in the coordinates of the passing point (1, 3), we get:
3 = a (1)²
3 = a
Therefore, the value of "a" is 5.
Hence, the equation of the parabola is:
y = 3x²

8x2 - 6x + 3 – 2x – 10x?
Answer:
8[tex]x^{2}[/tex] + 3 + -6x
Step-by-step explanation:
First we need to find the like terms so that we could add them. In this case the like terms are,
1. 6x , -2x , -10x
So, these are the only terms that we can add in this expression.
Hence,
=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)
=> 8[tex]x^{2}[/tex] + 3 + -6x
And this is as simple as this expression can go until we find the value of "x" which is not yet told.

The temperature at 6.00 am was - 12 the temperature increased by 1/2 each hour for 6 hours what was the temperature in degrees Fahrenheit at noon
Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit
Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit
