She received 1 package from SendQuick Package Service, 2 packages from Ralph's Express and 8 packages from Speedy Delivery
What is a word problem?A word problem is a mathematical exercise which is in the form of a hypothetical question that needs mathematical analysis and equations to be solved.
Let SQPS represent SendQuick Package Service
SD represent Speedy Delivery
RE represent Ralph's Express, then:
Let the number of packages from SQPS be x
The number of packages from RE will be x+1
The number of packages from SD will be 4(x+1)
Given that the total number of packages received is 11, then:
x + x+1 + 4(x+1) = 11
x + x+1 + 4x + 4 = 11
6x + 5 = 11
6x = 11-5
6x = 6
x = 1
x = 1 package from SQPS
x + 1 = 2 packages from RE
4(x+1) = 8 packages from SD
Therefore, Erica Franz received 1 package from SendQuick Package Service, 2 packages from Ralph's Express and 8 packages from Speedy Delivery

Answer:
(4,-5)
Step-by-step explanation:
A spinner with 10 equally sized slices is shown below. (2 slices are red, 4 are blue, and 4 are yellow.) The dial is spun and stops on a slice at random. What is the probability that the dial stops on a slice that is not red?Write your answer as a fraction or a whole number.
We will have the following:
Since there are 8 slices that are not red, the probability will be given by:
[tex]p=\frac{8}{10}\Rightarrow p=\frac{4}{5}\Rightarrow p=0.8[/tex]So, the probability will be of 4/5, that is 80%.

Answer:
x = 23
y = 119
Step-by-step explanation:
Line m is parallel to line n and the angle given as 61 and the angle that is represented with 4x - 31 are alternate angles and have equal measurement.
We can write the following equation based on this information:
4x - 31 = 61 add 31 to both sides
4x = 92 divide both sides by 4
x = 23
now onto y,
the angle represented with y and the angle that is represented with 4x - 31 are supplementary and their measures add up to 180:
4x - 31 + y = 180 replace x with 23
4*23 - 31 + y = 180
92 - 31 + y = 180 subtract like terms
61 + y = 180 subtract 61 from both sides
y = 119

A new restaurant just opened up in your
neighborhood. One soda costs $2.75, and five
sodas cost $13.75. Is the cost a proportional or
non-proportional relationship?
proportional
not enough information
non-proportional
The cost for the soda is proportional.
How to calculate the value?For there to be a proportional relationship, there must be a constant.
In this case, one soda costs $2.75.
Also, five sodas cost $13.75. The cost per soda will be:
= $13.75 / 5
= $2.75
Since the values of $2.75 are the same, it has a proportional relationship.

Micah has an electricity plan where he is charged a monthly fixed rate of $3.18 and a usage fee of $0.14 per kilowatt-hour. In the equation below, x represents the amount of electricity he used, and y represents the amount Micah was charged for electricity. y = $0.14x + $3.18 If Micah was charged $143.18 for electricity last month, how much electricity did he use? A. 140 kilowatt-hours B. 45 kilowatt-hours C. 1,023 kilowatt-hours D. 1,000 kilowatt-hours Reset Submit
Answer:
D. 1,000 kilowatt-hours
Step-by-step explanation:
Given:
[tex]y=0.14x+3.18[/tex]
If Micah was charged $143.18, then:
[tex]143.18=0.14x+3.18[/tex]
First, subtract 3.18 from both sides:
[tex]140.00=0.14x[/tex]
Then, divide both sides by 0.14:

A jar contains only pennies, nickels, dimes, and quarters. There are 28 pennies, 26 dimes, and 23 quarters. The rest of the coins are nickels. There are 90 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
If n represents of nickels in the jar, then the equation that can be used to find n is; n + 77 = 90
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Assume that n represent the number of nickels in the jar.
Given that the jar contains only , pennies, nickels, dimes, and quarters. There are 28 pennies, 26 dimes, and 23 quarters. The rest of the coins are nickels.
This means that the total number if pennies, dimes and quarters would be;
23 + 28 + 26 = 77
This means that the number of coins that are not nickel = is 77
The total number of coins in the jar is 90. Therefore, the equation that can be used to find n is;
n + 77 = 90
n = 90- 77
n = 13 nickels

Nishnat can trade box tops only for printer.
Nishant keeps the box tops in 38 folders.
Each folder contains 80 box tops.
Number of box tops nishant has = number of folders x number of box tops in each folder
Number of box tops nishant has = 38 x 80
Number of box tops nishant has = 3040
For printer, he needs 1500 box tops
1500 < 3040
So, he can trade box tops for a printer.
For digital camera, he needs 3500 box tops
3500 > 3040
So, he can not trade box tops for a digital camera.
For tablet computer, he needs 5000 box tops
5000 > 3040
So, he cannot trade box tops for a tablet computer,
Therefore, Nishnat can trade box tops only for printer.

The price of Apple stock, A(X), over a 12 month period decreased and thenincreased according to the equation A(x) = x x 0, where x equals the number ofmonths. The 2 - 6 + 2 price of Baller stock B(x), increased according to theequation B(x) = 3x + 2 over the same 12-month period. When were both stockvalues the same?
The question is: When we're both stock values the same? Then all you have to do is match both equations and solve for x, like this
[tex]\begin{gathered} A(x)=x^2-6x+20 \\ B(x)=3x+2 \\ \text{ Matching you have} \\ x^2-6x+20=3x+2 \\ \text{Subtract 3x from both sides of the equation} \\ x^2-6x+20-3x=3x+2-3x \\ x^2-9x+20=2 \end{gathered}[/tex][tex]\begin{gathered} \text{Now subtract 2 from both sides of the equation} \\ x^2-9x+20-2=2-2 \\ x^2-9x+18=0 \end{gathered}[/tex]Factoring the trinomial you get

ANSWER
$28
EXPLANATION
We have that the entry fee is $10 and for each ride, $6 must be paid.
We want to complete the table by finding the cost of 3 rides.
First, let us represent the cost of going to the fair and taking the ride.
Let the number of rides a person takes by x.
We have that the cost of taking x rides will be the entry fee plus the cost of each ride taken:
Cost = 10 + 6x
So, for taking 3 rides, it will cost:
Cost = 10 + 6(3)
Cost = 10 + 18
Cost = $28
That is the cost of taking 3 rides.

Identify the graphs of y 2|x+2|-6 and y=-2 in the same coordinate plane
The graphs of the absolute value function y = 2|x + 2| - 6 and the horizontal line y = -2 are given on the image at the end of the answer.
How to build the graphs?The definition of the absolute value function is given as follows:
y = |x - h| + k.
In which the coordinates of the vertex are (h,k), representing the turning point of the graph of the absolute value function, the point in which the function makes the "V".
In this problem, the definition of the function is:
y = 2|x + 2| - 6.
Hence the coordinates of the vertex are:
(-2, -6).
The multiplication by 2 represents a vertical stretch but is not related to the vertex of the function.
y = -2 is a horizontal line, and the graph with these two functions is given by the image at the end of the answer.
