How many bags of grapes had a weight of 3/8 pounds or less?
Kyra went to the grocery store on Monday and bought 5 apples and 2 oranges for a total of $3.45. On Thursday she bought 3 oranges and 7 apples for a total of $4.90. How much do the apples and oranges cost?
Answer:
The apples and oranges cost .49 cents each
Step-by-step explanation:
When we do 5 + 2 we get 7, 7 is our number of apples and oranges combined.
Next we do 3.45 divided by 7 and get .49
When we do the same for thursday, we get the same answer which confirms our answer.
The table below shows the value of a car during certain years . Using an exponential model , write an equation for the curve of best fit, then estimate the value of the car in 2016 .
The exponential function that gives the value of the car in t years after 2008 is:
[tex]A(t) = 27500(0.88)^t[/tex].
Using the function, the estimate for the value of the car in 2016 is of $9,900.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem:
The initial value is of A(0) = 27,500.Considering the first year change, we have that 1 - r = 24200/27500 = 0.88.Hence, the equation is:
[tex]A(t) = 27500(0.88)^t[/tex]
2016 is 8 years after 2008, hence the value of the car will be given by:
[tex]A(8) = 27500(0.88)^8 = 9900[/tex]

The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let y represent the value of the car after x years after 2008, hence:
at x = 0, y = 27500
27500 = ab⁰
a = 27500
At x = 1, y = 24200, hence:
24200 = 27500b¹
b = 0.88
y = 27500(0.88)ˣ
In 2016, x = 8, hence:
y = 27500(0.88)⁸ = 9890
The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890

1. Avenue A runs parallel to Avenue B, and Avenue C runs diagonally across the two streets. Use the marked angles to write and solve an equation to find the value of x. 10x + 6 Avenue A 6x – 18 Avenue C Avenue B
The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12.
How to determine the value of x from a system of angles
In this question we must apply all Euclidean theorems of angles between two parallel lines cut by a third diagonal line. The internal angle between avenues B and C equals 6 · x - 18 and the external angle between avenues A and C equals 10 · x + 6.
By alternate internal angles between parallel lines we infer the measure of the internal angle between the avenues A and C equals 6 · x - 18, and definition of supplementary angles we have the following expression:
(6 · x - 18) + (10 · x + 6) = 180
16 · x - 12 = 180
16 · x = 192
x = 12
The value of the equations related to the angle system related to the two parallel lines (avenues A and B) cut by a third diagonal line (avenue C) is equal to to 12. [tex]\blacksquare[/tex]

Answer: 3) [tex]\frac{x+3}{x}[/tex]
Step-by-step explanation:
Start by factoring the numerator by grouping
[tex]\frac{x^3+2x^2-9x-18}{x^3-x^2-6x} \\\frac{(x^3+2x^2)+(-9x-18)}{x^3-x^2-6x} \\\frac{x^2(x+2)-9(x+2)}{x^3-x^2-6x} \\\frac{(x^2-9)(x+2)}{x^3-x^2-6x} \\\frac{(x-3)(x+3)(x+2)}{x^3-x^2-6x}[/tex]
Now factor the denominator
[tex]\\\frac{(x-3)(x+3)(x+2)}{x^3-x^2-6x}\\ \\\frac{(x-3)(x+3)(x+2)}{x(x^2-x-6)}\\[/tex]
Factor the trinomials by finding two numbers that add to get -1 and multiply to get -6. In this case the numbers are -3 and 2
[tex]\\\frac{(x-3)(x+3)(x+2)}{x(x^2-x-6)}\\\\\\\frac{(x-3)(x+3)(x+2)}{x(x-3)(x+2)}\\[/tex]
Cancel out the terms that are both in the numerator and denominator. In this case they are (x-3) and (x+2)

Using Reflection, ADP and BCP are the same.
If line PD is equal to line PC, angle 1 is equal to angle 2 and angle 3 is equal to angle 4, then line AP is equal and a reflection of line BP, line AD is also equal and a reflection of line BC
In reflected angles, the sides and angles of the shape are not altered.

Barrett is 5 years less than half Cayden’s age. If Barrett is 11 years old, what is Cayden’s age?
(Someone help I’ve done this problem multiple times and I keep getting different answers)
The age of Cayden is given by the equation C = 32 years old
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 age of Cayden be C
Let the age of Barret be B = 11 years old
And , Barrett is 5 years less than half Cayden’s age
B = ( C / 2 ) - 5
On simplifying the equation , we get
11 = ( C / 2 ) - 5
Adding 5 on both sides , we get
16 = C / 2
Multiply by 2 on both sides , we getr
C = 32 years old
Therefore , the value of C is 32 years
Hence , age of Cayden is 32 years
