Algebraic expression for each statement in terms of w would be:
Each pencil will cost: w/5.
A pen will cost: w/5 + 0.35
Number of pencils 20 dollars will buy = w/5 = 20/5 =4 pencils.
What is an Algebraic Expression?Algebraic expression in mathematics is an expression that is made up of variables, constant, and mathematical symbols, which can be used to represent a statement.
Thus:
Let w represents the price for 5 pencils.
Each pencil will cost: w/5.
A pen will cost: w/5 + 0.35
a. cost in dollars for a pen = w/5 + 0.35
b. Number of pencils 20 dollars will buy = w/5 = 20/5 =4 pencils.

Raheel is comparing the cost of two parking garages. Garage A charges a flat fee of $6 per car plus $0.50 per hour. Garage B charges a flat fee of $2 per car plus $1 per hour.
Answer:
$6 + .50x = $2 + $1.00x
4 = .50x
8hr = x, the number of hours when both garages cost the same amount
$6 + .50 x 8 =
$10 would be the cost a both garages after 8 hours
Step-by-step explanation:
#A
Flat fee=6Rate of change=0.5Equation in slope intercept form
y=mx+by=0.5x+6#B
Flat fee=2$Rate of change=1Equation in slope intercept form
y=x+2Now for compare take any no
Let's take 10
For garage A
y=0.5(10)+6=5+6=11$For garage B
y=10+2=12$Hence Garage B is charging more
Do 42 and 43 pleasee
Answer:
42. A
43. C
Step-by-step explanation:
42. The answer is A. This is because we are distributing (multiplying) the 7.2 to each number in the parentheses.
43. If Hal ran 4.5 laps, then he ran...
0.65 mil (since each lap is 0.65 miles)* 4.5 (laps) = C. 2.925 miles.

What is an ideal gas equation?An ideal gas is a theoretical composed of a set of randomly moving gas particles that interacts only through elastic collision.
Given
A balloon containing 0.040 mol of a gas with a volume of 5.0 mL was expanded to 1.0 L.
[tex] \rm V_1 = 5 \ mL\\ V_2 = 1000 \ mL\\ n_1 = 0.040 \ mol [/tex]

In a camp ,there is enough flour for 300 persons for 42 days.How long will the flour last if 20 more persons join the camp
Answer/Step-by-step explanation:
Direct proportion: If a variable increases then other variable also increases with a constant factor i.e. y = kx
Inverse proportion: if a variable increases then other variable decreases with a constant factor i.e xy = k
Assume that food will last for d days if 20 more persons join the camp.
Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,
Days x number of persons = constant
Equate the product of 300 persons and 42 days with (300 + 20) person and d days to solve for d.
[tex](300+20) *d=300*42[/tex]
⇒ [tex]d = \frac{12600}{320}[/tex]
⇒ [tex]d =\frac{1260}{32}[/tex]
⇒ [tex]d=\frac{315}{8}[/tex]
⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]
Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction

You and your friend leave your houses at the same time to meet at a restaurant. The distance (in miles) your friend
is from the restaurant is given by y = -40% + 200, where I is the number of hours since your friend left home.
You live 100 miles from the restaurant and arrive at the same time as your friend. Write a linear equation that
represents your distance from the restaurant
Answer:
When x=0 the friend is 200 miles from the restaurant and at x=5 the friend reaches the restaurant. When x=0 you are 100 miles from the restaurant, so 100 is the y intercept, and when x=5 you reach the restaurant so 5 is the x intercept. We have y=mx+100 and y=0 when x=5, so 0=5m+100 therefore m=-20 and the equation is y=-20x+100.
which of the following polynomials has a graph with odd symmetry? a. 7x^4+13x^3-11 b. 5x^7+4x^6+3x^5+x c.13x^5 -1/2x^3+7x+3 d. 8x^5+7x^3-5x
Answer:
D) [tex]f(x)=8x^5+7x^3-5x[/tex]
Step-by-step explanation:
A function is odd if its graph is symmetric to the origin, which we can check this if [tex]f(-x)=-f(x)[/tex] is true:
Option A
[tex]f(x)=7x^4+13x^3-11\\\\f(-x)=7(-x)^4+13(-x)^3-11\\\\f(-x)=7x^4-13x^3-11[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option B
[tex]f(x)=5x^7+4x^6+3x^5+x\\\\f(-x)=5(-x)^7+4(-x)^6+3(-x)^5+x\\\\f(-x)=-5x^7+4x^6-3x^5+x[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option C
[tex]f(x)=13x^5-\frac{1}{2}x^3+7x+3\\\\f(-x)=13(-x)^5-\frac{1}{2}(-x)^4+7(-x)+3\\ \\f(-x)=-13x^5-\frac{1}{2}x^4-7x+3[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option D
[tex]f(x)=8x^5+7x^3-5x\\\\f(-x)=8(-x)^5+7(-x)^3-5(-x)\\\\f(-x)=-8x^5-7x^3+5x[/tex]
Since [tex]f(-x)=-f(x)[/tex], then the function DOES have odd symmetry. You can also see that the function is odd because every term has an odd exponent.
You can use the formula a = to find the batting average a of a batter who has h hits in n times at bat. in If a person has a batting average of 280 and has been at bat 300 times, how many hits does the batter have?
Answer:
Step-by-step explanation:
BA = Number of hits / Times at bat
BA = 280 / 300
BA = 0.933
No one past or present, has ever had that kind of batting average.
