Answer:
According to this, the answer is:
a. x=(c-0.50y)/0.75
b. c=0.75x+0.50y
Step-by-step explanation:
With the information provided, the total cost in cents is equal to the result of the price of the 75 cent bars for the amount of bars plus the price of the 50 cent bars for the amount of bars, which would be:
c=0.75x+0.50y, where:
x is the amount of the 75 cent bars
y is the amount of the 50 cent bars
Now, you can solve for x to determine the expression that represents the number of 75 cent bars if she bought y 50 cent bars:
c-0.50y=0.75x
(c-0.50y)/0.75=x
x=(c-0.50y)/0.75
According to this, the answer is:
a. x=(c-0.50y)/0.75
b. c=0.75x+0.50y

If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k
Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k

A rectangular prism has a width of x cm. Its length is 3 cm more than its width, and its height is 4 cm more than its length. Write an algebraic expression, in simplified form, for the volume of the prism.
Answer:
Step-by-step explanation:
Width: x
Length: x + 3
Height: x + 3 + 4 = x + 7
Volume of prism = area of cross section x length
Area of cross section = width x height = x ( x + 7 ) = x² + 7x
Volume = (x + 4) x (x² + 7x)
= x³ + 7x² + 4x² + 28x
= x³ + 11x² + 28x
The algebraic expression which shows the volume of the prism is [tex]x^{3}+10x^{2} +21x[/tex].
What is volume?Volume is basically amount of substance a container can hold in its capacity. Volume of rectangular prism is the product of length, breadth and height of prism.
How to calculate volume?We know that volume of rectangular prism is L*B*H.
We have been given that width is x cm.
According to question length will be x+3,
Height will be x+3+4
=x+7
Volume will be =x(x+3)(x+7)
Multiply the expressions,
=x([tex]x^{2}[/tex]+3x+7x+21)
=x([tex]x^{2}[/tex]+10x+21)
=[tex]x^{3} +10x^{2} +21x[/tex]
Hence volume of rectangular prism can be expressed as [tex]x^{3} +10x^{2} +21x[/tex].

There is a line that includes that point (-6,3)and has a slope of 1/10 . What is its equation in point-slope form?
Answer:
y = 1/10 x + 18/5
Step-by-step explanation:
The general form of the equation of a line is given as
y = mx + c where m is the slope and c is the intercept
For a line with given points (x1, y1), the equation is given as
y-y1 = m(x-x1)
Hence if there is a line that includes that point (-6,3) and has a slope of 1/10 then the line
y - 3 = 1/10(x --6)
multiply both sides by 10
10y - 30 = x + 6
Rearrange
10y = x + 6 + 30
10y = x + 36
y = 1/10 x + 36/10
y = 1/10 x + 18/5
Sam ran several errands and used 7 gallons of gas. There were 5 gallons left in the tank. (Use g as a variable.)

[tex]Left = 5[/tex]
Required
Determine the additional gallons used (g)
This is calculated as:
[tex]Left+ g= Used[/tex]
So, we have:
[tex]5 + g = 7[/tex]
Make g the subject

Write an equation in slope intercept form for the line that passes through (-2,3) and is parallel to the graph of y=-3/4x+4
Answer:
When the equation parallel the graph then the measure of the equation is - 3/4
Then the equation is y=-3/4x+c
By using the point(-2,3)
[tex] y = \frac{ - 3}{4} x + c \\ 3 = \frac{ - 3}{4} \times - 2 + c \\ 12 = 6 + 4c \\ 4c = 6 \\ c = \frac{3}{2} [/tex]
Then the equation is
[tex]y = \frac{ - 3}{4} x + \frac{3}{2} [/tex]

If the perimeter of the triangle is 90. Then the value of the variable x will be12.5.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The sum of all the sides of the triangle will be known as the perimeter of the triangle.
In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.
The dimension of the triangle are 3x, 3x, and 15. If the perimeter of the triangle is 90. Then the equation is given as,
3x + 3x + 15 = 90
6x = 90 - 15
6x = 85
x = 12.5
The value of the variable x will be12.5.

Answer:
89 seats are not being used
Step-by-step explanation:
You subtract the seats being used by teachers
342 - 75 =267
Change 2/3 into a percentage = 66.6%
Find 66.6% of 267= 177.8 (I rounded up to 178)
Then subtract 177.8/178 from 267 to find the amount of seats not being used.
The amount of seats not being used would come down to 89 seats.
