eight hundred tickets were sold for a theater production
Answer:
280 student tickets
520 adult tickets
Explanation:
I'm guessing this is the question you meant to ask:
Eight hundred tickets were sold for a movie production and the receipts for the performance wear $8600. The tickets for adults and students sold for $12.50 and $7.50, respectively. How many of each ticket were sold?
One month Dante rented 2 movies and 3 video games for a total of$22 . The next month he rented 4 movies and 8 video games for a total of$57 . Find the rental cost for each movie and each video game.
Answer:
x = $1.25; y = $6.50
Step-by-step explanation:
Let x be the cost of movies and y be cost of video games.
Month 1 has 2x+3y = 22
So here x = (22-3y)/2 and y = (22-2x)/3
Month 2 has 4x+8y =57
Here x = (57-8y)/4 and y = (57-4x)/8
Now you have two options: Find the y or the x. I will demo the x and you can try the y if you wish.
(22-2x)/3 = (57-4x)/8
176-16x = 171-12x
-4x = -5
x = 1.25
Now with the x found, you plug it into either of the y equations to figure out the other variable.
y = (22-2(1.25))/3
y = 6.5
And to double check:
y = (57-4(1.25))/8
y = 6.5

The numbers are measurements of radius diameter and circumference of circles A and B. Circle A is smaller than Circle B which number belongs to which quantity? 2.5, 5, 7.6, 15.2, 15.7, 47.7
Step-by-step explanation:
a diameter is always twice the radius.
the only pairs in this list, where one number is twice the other, is :
2.5 and 5
7.6 and 15.2
so,
2.5 is the radius of A
5 is the diameter of A
7.6 is the radius of B
15.2 is the diameter of B
15.7 is then the circumference of A (as the smaller of the remaining 2 numbers).
47.7 is the circumference of B.
this is also proven by the formula for the circumference of a circle : c = 2×pi×r

Nonsense, Or not part the question I ask for will be reported.
Thanks~
Answer:
x=–(3/4)
Step-by-step explanation:
Subtract 5x from both sides:
−3x−5x=5x+6−5x
Simplify:
−8x=6
Divide both sides by −8
−8x/−8 =6/−8
Simplify again, result will be:
x=−(3/4)

Kinetic energy can be calculated using the formula KE=1/2mv²,
where m= mass and v= velocity.
Calculate the kinetic energy of an object with mass 5kg moving at a velocity of 4m/s.
Answer:
40J
Step-by-step explanation:
YOU say 1/2 x 5 x4² ( 4 is velocity. 5 is mass )
it becomes 1/2 x5 x16
then it becomes 1/2 x 80
half of 80 is 40
the answer is then 40 JUOLES

Step-by-step explanation:
A quotient is a fraction.
A sum is addition.
A variable is an unknown number shown by using a letter.
Therefore, the answers for quotient and variable in this picture should be switched. However, the negative sign has to be included, so the quotient should be a -9/y.

Answer:
The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0
has solutions x = 2 and x = 3.
Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.
Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.
A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.
As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

Answer:

Step-by-step explanation:
y=3(x-1)
multiply
3(x-1)
then y=3x-3
y+1=4/3(x+3)
multiply 4/3(x+3)
y=4/3x+3
Answer:
1) D. y = 3x-3
2) A. y = 4/3 x+3
Step-by-step explanation:
1)
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : y-(3*x-3)=0
Step 1:
Equation of a Straight Line
Solve y-3x+3 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-3x+3 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000
y-intercept = -3/1 = -3.00000
Calculate the X-Intercept :
When y = 0 the value of x is 1/1 Our line therefore "cuts" the x axis at x= 1.00000
x-intercept = 3/3 = 1
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -3.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - (-3.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 6.000/2.000 = 3.000
Geometric figure: Straight Line
Slope = 6.000/2.000 = 3.000
x-intercept = 3/3 = 1
y-intercept = -3/1 = -3.00000
2)
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(4/3*x+3)=0
Step 1:
Simplify 4/3
Equation at the end of step 1:
y - ((4/3 • x) + 3) = 0
Step 2: Rewriting the whole as an Equivalent Fraction
Adding a whole to a fraction
Rewrite the whole as a fraction using 3 as the denominator :
3 = 3/1 = 3 · 3/3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
4x + 3 · 3/3 = 4x+9/3
Equation at the end of step 2:
y - (4x+9)/3=0
Step 3:
Rewriting the whole as an Equivalent Fraction :
Subtracting a fraction from a whole
Rewrite the whole as a fraction using 3 as the denominator :
y = y/1 = y · 3/3
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
y • 3 - ((4x+9)) 3y - 4x - 9
———————————————— = ———————————
3 3
Equation at the end of step
3
:
3y - 4x - 9
——————————— = 0

STEP

When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
3y-4x-9
——————— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3y-4x-9 = 0
Equation of a Straight Line
4.2 Solve 3y-4x-9 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3y-4x-9 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3/1 so this line "cuts" the y axis at y= 3.00000
y-intercept = 9/3 = 3
Calculate the X-Intercept :
When y = 0 the value of x is 9/-4 Our line therefore "cuts" the x axis at x=-2.25000
x-intercept = 9/-4 = -2.25000
Calculate the Slope :
Slope = 2.667/2.000 = 1.333
Geometric figure: Straight Line
Slope = 2.667/2.000 = 1.333
x-intercept = 9/-4 = -2.25000
y-intercept = 9/3 = 3
