A woman bought a bag of rice for $5700 and in 3 weeks later,she could only buy 3/4 of a bag for $5700. Find the percentage increase.
Answer: 25%
Step-by-step explanation:
3/4x=5700
x = 7600
7600 - 5700 = 1900

A rectangle has a height of x+ 9 and a width of x^2 + 2x
Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
X^2
+
2x
X
+
9
Answer:
x³ + 11x² + 18x
Step-by-step explanation:
(x² + 2x)(x + 9)
Step 1: Distribute x²+2x into x + 9.
x³ + 2x² + 9x² + 18x
Step 2: Combine like terms.
x³ + 11x² + 18x
The area of this rectangle is x³ + 11x² + 18x.
Answer:
Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x
Step-by-step explanation:
The height is (x + 9) and the width is (x^2 + 2x) and the the area of the rectangle is equal to: Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x

Least Common Multiple:

Calculating Multipliers :
3.2 Calculate multipliers for the two fractions
Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Deniminator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 2
Right_M = L.C.M / R_Deno = 1
Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 4 • 2
—————————————————— = —————
L.C.M 18
R. Mult. • R. Num. x
—————————————————— = ——
L.C.M 18
Adding fractions that have a common denominator :
3.4 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:

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:
8-x
——— • 18 = 0 • 18
18
Now, on the left hand side, the 18 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
8-x = 0
Solving a Single Variable Equation:
4.2 Solve : -x+8 = 0
Subtract 8 from both sides of the equation :
-x = -8
Multiply both sides of the equation by (-1) : x = 8
One solution was found :
x = 8

Miguel sells insurance. He earns a 6% commission on each sale he makes. Miguel has a goal of earning $600 in commissions. Miguel need to sell $ Worth of insurance to meet his goals
Answer: $12,000
Step-by-step explanation:
Miguel makes 6% on every sale he makes and wants to make $600 in commissions.
The amount he needs to sell is therefore the amount that has $600 as 5% of it.
Assume the amount of insurance needed is x.
x * 5% = 600
x = 600 / 5%
x = $12,000
what is 4x – 97 + 12 – x = -80.5
Answer: x - 1.5
4x – 97 + 12 – x = -80.5
3 x - 85 = -80.5
3 x - 85 +85 = -80.5 + 85
3x = -80.5 + 85
3x = 4.5
x = 1.5
Step-by-step explanation: hope this helps
Answer:
x=1.5
Step-by-step explanation:
4x-97+12-x=-80.5
Combine like terms
-97+12=-85
4x-x=3x
now you have 3x-85=-80.5
add 85 to both sides and now you have
3x=4.5
Now divide 3 to both sides and you get x=1.5

A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it
sets the price at x dollars, it will sell f(x) = 4,920 - 6x phones. Therefore, the company's revenue is x . (4,920 - 6x). Find
the price x that will maximize the company's revenue.
Answer:
410
Step-by-step explanation:
Revenue is given by the relation :
x . (4,920 - 6x)
F(x) = 4920x - 6x²
To obtain the price, x which maximizes revenue, we take the first derivative of the revenue function and equate to 0
F'(x) = 0
F'(x) = 4920 - 12x
4920 - 12x = 0
-12x = - 4920
x = 4920 / 12
x = 410
Price will be 410

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the temperatures on different days be represented by the table
Now , total temperature is S = -6 + 3 + 4 - 2 - 1
On simplifying the equation , we get
S = -2°C
Hence , the temperature is S = -2°C
