The scenario represented by the linear function y = x + 2 is given by:
Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The y-intercept is of 2, as when x = 0, y = 2.The slope is of 1, as when x changes by 2, y also changes by 2, hence m = 2/2 = 1.Thus the function is given by:
y = x + 2.
Which means that the initial amount is of $2, and increases by $1 for each unit of time, hence the correct option is:
Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

Step-by-step explanation:
Tony has x quarters. Jane has three more quarters than Tony. Rob has twice as many quarters as Jane. Together, Rob and Jane have $4.50 in quarters. Complete each statement. (A) The expression x + 3 represents the number of quarters Jane has. (B) The expression x – 3 represents the number of quarters Rob has. (C) Tony has quarters.
Answer:
x = 3 quarters
Step-by-step explanation:
Tony = x quarters
Jane = (x + 3) quarters
Rob = 2(x + 3) quarters
Rob and Jane have $4.50 in quarters.
$1 = 4 quarters.
$4.50 = ( 4 × 4.5 ) quarters
= 18 quarters.
(x + 3) + 2(x + 3) = 18
x + 3 + 2x + 6 = 18
3x + 9 = 18
3x = 18 - 9
3x = 9
x = 9/3
x = 3
(A) The expression x + 3 represents the number of quarters Jane has. YES
x + 3
= 3 + 3
= 6 quarters
(B) The expression x – 3 represents the number of quarters Rob has.
NO
(C) Tony has quarters.
Tony = x quarters
= 3 quarters
Rob = 2(x + 3) quarters
= 2(3 + 3) quarters
= 2(6) quarters
= 12 quarters
Answer:
(A) The expression x + 3 represents the number of quarters Jane has.
B) The expression 2(x+3) represents the number of quarters Rob has.
(C) Tony has 3 quarters.

Answer:
50
Step-by-step explanation:
Let's drag the x line to the other side with the 14 and 48.
Then we do the Pythagorean theorem like 14^2 + 48^2 = x^2.
So then we get that x^2 is 2500
then we clearly know the square root of 2500 is 50
So 50 is our answer.
Answer:
x = 50in.
Step-by-step explanation:
[tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex]
[tex]14^{2}[/tex] + [tex]48^{2}[/tex] = 2500
[tex]\sqrt{2500}[/tex] = 50

|) Mei Li is going orange
picking. She is choosing
between two orange
orchards. The cost of a
basket of oranges at each
orchard is shown.
Which orchard should Mei
Li choose? Explain.
Answer:
Annie's Orange Grove
Step-by-step explanation:
* you need to find out how much each pound of oranges cost at both orchards.
* to do so you take the total amount of money and divide it by the number of pounds you get.
1) 7.25 ÷ 20 = .36
2) 5 ÷12 = .4
* as you can see .36 is less than .4 and therefore is the better deal.

A package of 8 pens costs $1.09. Milo’s work to find the unit price of the pack is shown below.
8p/$1.09 =
8÷$1.09 =

Where did Milo make his first error?
Answer:
He wrote the unit rate incorrectly.
Step-by-step explanation:
Given
[tex]Pens = 8[/tex]
[tex]Cost = \$1.09[/tex]
Required
Determine Milo's error
First, we need to solve for the unit price; then compare our results with Milo's
[tex]Unit\ Price = \frac{Cost}{Pens}[/tex]
[tex]Unit\ Price = \frac{\$1.09}{8}[/tex]
[tex]Unit\ Price = \$0.13625[/tex]

The four members of the "Fantastic Four" made 40 cookies each for the bake sale. They know that 35% of their cookies are chocolate chip.
How many chocolate chip cookies were made?
Answer:
56 Chocolate Chip cookies
Step-by-step explanation:
To find the answer first add up all of the cookies, in this case, 40+40+40+40 witch equals 160. then find 35% of that. This can be done by dividing 160 by 100 to get 1% then multiplying that by 35 to get 35% witch is 56. Therefore you have 56 Chocolate Chip cookies.

Long division is easier than you think. Here's how to solve this problem:
1. See how many times 36 can go into 66.
Multiply until you reach a number that is closest (or exact) to 66.
36 x 1 = 36; 36 x 2 = 72.
72 is over 66, so 2 doesn't work. Therefore, we'd put "1" in the first space on the shelf (right above the 6).
2. Subtract.
Now that we have "1" on the shelf, you need to subtract 36 by 66. We do this because 36 x 1 is 36. If it were the number "2" on the shelf, we'd subtract 72, and so on.
66 - 36 = 30.
3. See how many times 36 can go into 30.
Since it can't go into 30, we bring the 3 down (hence the arrow pointing down). The number is now 303.
4. See how many times 36 can go into 303.
I won't write it all out, but after multiplying 1-7 by 36, we find that the closest solution is 36 x 8 = 288.
We put "8" on the shelf, next to "1".
5. Subtract.
Now that "8" is on the shelf, we subtract 288 by 303, which gives us 15.
Since 36 cannot go into 15, and there are no more numbers we can drag down, your remainder is 15.
Your answer is:
36 R 15
The first two boxes under 663 should be filled with 36, the next three under that should have 303, the next three should have 288, and the final two boxes should have 15.

Step-by-step explanation:
The surface area of Earth is approximately 5.1 x 108 km2. The surface area of Jupiter is approximately 6.2 x 1010 km2. Approximately
how many times larger is Jupiter's surface area than Earth's surface area?
A 8
B 12
C 80
D 120
Answer:
The correct answer is: Option D: 120
Step-by-step explanation:
Given that
[tex]S_E = 5.1*10^8\ km^2\\S_J = 6.2*10^{10}\ km^2[/tex]
In order to find how much larger is the area of Jupiter we will divide the surface area of Jupiter by the Surface area of Earth. First of all we will have to equate the exponents of 10 so that the cutting can be done
Now,
[tex]= \frac{S_J}{S_E}\\= \frac{6.2*10^{10}}{5.1*10^8}[/tex]
10^10 can be written as: 10^8*10^2
[tex]=\frac{6.2*10^2*10^8}{5.1*10^8}\\= \frac{6.2*100}{5.1}\\=\frac{620}{5.1}\\=121.5686[/tex]
Closest to 121 is 120.
Approximately Jupiter's surface area is 120 times larger then Earth's surface area.
Hence,
The correct answer is: Option D: 120
The theater sells two types of tickets: adult tickets for $14 and child tickets for $6.
Last night, the theater sold a total of 438 tickets for a total of $5012. How many adult tickets did the theater sell last night?
Answer:
Number of adult tickets = 298
Number of child tickets = 140
Step-by-step explanation:
Number of adult tickets = a
Number of child tickets = c
a + c = 438 -------------------(I)
14a + 6c = 5012 ----------------(II)
Multiply equation (I) by (-6) and then add, so c will be eliminated.
(I) * (-6) -6a - 6c = -2628
(II) 14a + 6c = 5012 {Add}
8a = 2384
a = 2384/8
a = 298
Plugin a = 298 in equation (I)
298 + c = 438
c = 438 - 298
c = 140
