A bicycle store costs $1800 per month to operate. The store pays an average of $35 per bike. The average selling price of each bicycle is $75. How many bicycles must the store sell each month to break even?
Answer:
45
Step-by-step explanation:
1800 total
35 dollars per bike
75 bucks to sell bike
75-35= 40
40 bucks per bike
1800 divided by 40 = 45 so 45 bikes

if y=3x^3+x^2-5 and z=x^2-12 what polynomial is equivalent to 2(y+z)
Answer:
2y + 2z
6x³+2x²-10 + 2x²-24
6x³+4x²-34 ■
Step-by-step explanation:
The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
What is Polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.
Here, y = 3x³+x²-5 and z = x²-12
Now,
2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )
2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )
2 ( y + z ) = 6x³ + 4x² - 34
Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

Haha there is no question
Step-by-step explanation:
We went to the store and bought 6 giant candy bars and 2 small
bags of jawbreakers and spent $13.00. My friend went to the store
and bought 4 giant candy bars and 6 small bags of jawbreakers
and spent $11.00. How much did a candy bar cost? How much did
a bag of jawbreakers cost?
Answer:
Giant Candy Bar: 2$
Small Bags of Jawbreakers: .50$
Step-by-step explanation:
First you make out the equations, with the variables of c for giant candy bars and j for the small bags of jaw breakers.
First equation we make is 6c+2j=13
The second equation is 4c+6j=11.
You can then make one of the equations a negative and equal to the other. What I mean is we can use the elimination method. So I choose to do -18c+-6j=-39 (Multiplied by -3) so we can eliminate the 2 6js and get 4c=11 and -18c=-39. You then add the remaining equations together to get -14c=-28, so c=2. Using that we can then chose an equation to substitute c with. Ill choose the first one, so you get 6(2)+2j=13. 12+2j=13; 2j=1. By simplifying, you get the jawbreakers as .50 dollars.

A milk tank at a dairy farm has the form of a rectangular prism. The tank is 3.5 feet wide. The width of the tank is 5/7 of its length, and the height is 4/5 of its width. How many cubic feet of milk can the tank hold? How many pounds of milk can it hold if 1 cubic foot of milk weighs 66.5 lbs?
Answer:
48.02 or 48 1/50 cubic feet and 3193.33 or 3193 33/100 LB ( I do rsm too )
Step-by-step explanation:
The width is 3.5
The length is 3.5*7/5 which is 4.9
The height is 4/5 of 3.5 which is 2.8
So, the volume in cubic feet is 3.5*4.9*2.8 which is 48.02 or 48 1/50
So, the amount in Lb is 66.5*48.02 which is 3193.33 or 3193 33/100
A tank can hold [tex]\boldsymbol{24.5}[/tex] cubic feet of milk and a tank can hold [tex]\boldsymbol{1629.25}[/tex] pounds.
Rectangular prismA rectangular prism is a three-dimensional solid object that has six rectangle-shaped faces.
Length of a rectangular prism [tex](l)=3.5[/tex] feet
Width of a rectangular prism [tex](w)=\frac{5}{7}(3.5)[/tex]
[tex]=2.5[/tex] feet
Height of a rectangular prism [tex](h)=\frac{4}{5}(3.5)[/tex]
[tex]=2.8[/tex] feet
Volume of a milk tank [tex]=lwh[/tex]
[tex]=3.5(2.5)(2.8)[/tex]
[tex]=\boldsymbol{24.5}[/tex] cubic feet
[tex]=24.5(66.5)[/tex] pounds
[tex]=\boldsymbol{1629.25}[/tex] pounds
So, a tank can hold [tex]\boldsymbol{24.5}[/tex] cubic feet of milk and a tank can hold [tex]\boldsymbol{1629.25}[/tex] pounds.

A car traveled 25 miles of a 200 mile trip to its destination. The car travels at a speed of 35 miles per hour. How many hours until the car reaches its destination? Respond to the two questions below and show all work.
Answer: 5 hours
Step-by-step explanation:
The car has already travelled 25 miles into the 200 miles that it is meant to travel.
The distance left is therefore:
= 200 - 25
= 175 miles
The car is travelling at 35 miles per hour.
The time left for travel is:
= Distance / Speed
= 175 / 35
= 5 hours

Answer:
No, X=7
Step-by-step explanation:
Answer:
Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:
x-4y=6
x+4y=12
we see here that elimination would best fit:
x+x+4y-4y=6+12
or:
x=2y-3
7x+3y-81=23
substitute (2y-3) for x.
Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)
and use the quadratic formula:
x=(-b±sqrt(b^2-4ac))/2a

Solve the system of equations using subtraction. y = -2x + 1 4x + 2y = -3 a. Infinity many solutions b. No solution c. (0,-5) d. (-5,0)
Given:
The given system of equation is:
[tex]y=-2x+1[/tex]
[tex]4x+2y=-3[/tex]
To find:
The solution of given system of equations using subtraction.
Solution:
We have,
[tex]y=-2x+1[/tex] ...(i)
[tex]4x+2y=-3[/tex] ...(ii)
First equation can be rewritten as
[tex]2x+y=1[/tex] (Adding 2x on both sides)
[tex]4x+2y=2[/tex] ...(iii) (Multiplying both sides by 2)
After subtracting (ii) from (iii), we get
[tex]4x+2y-(4x+2y)=2-(-3)[/tex]
[tex]4x+2y-4x-2y=2+3[/tex]
[tex]0=5[/tex]
This statement is false because [tex]0\neq 5[/tex]. It means, there is no value of x and y for which the given system of equations are true.
Therefore, the given system of equations has no solution and the correct option is b.

Answer:
The height of the triangle is: h = 6.4 cm
Step-by-step explanation:
Given
Area of the triangle A = 40 cm²
The Base of the triangle b = 12.5 cm
To determine
height of triangle h = ?
We know that the area A of a triangle is:
A = 1/2 bh
where
b is the baseh is the height of the triangle.so
A = 1/2 bh
substituting A = 40 and b = 12.5
40 = 1/2 (12.5) h
40 × 2 = 12.5 h
12.5 h = 80
divide both sides by 12.5
12.5h/12.5 = 80/12.5
h = 6.4 cm
Thus, the height of the triangle is: h = 6.4 cm

O (-6,8)
O (6,4)
O (8,6)
O (4, 6)
Answer:
The solution to the system of equations will be: (-6, 24)
Step-by-step explanation:
Given the system of equations
y = -3x+6
x = -6
substituting x = -6 in the equation y = -3x+6
y = -3x+6
y = -3(-6) + 6
y = 18+6
y = 24
Therefore, the solution to the system of equations will be: (-6, 24)
Note: it seems you have not mentioned the correct option in the answer choice as the correct choice is (-6, 24).

O (1,2)
O (1.5, 2)
O (1.5, -2)
(3,-2)
Answer:
(1.5, -2)
Step-by-step explanation:
First subract -3 from 6 to find the total distance of the line segment.
6 - (-3)
Two negatives make a positive
6 + 3
9 units distance
Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.
-3 + 4.5
-3 + 3 + 1.5
(1.5, -2)
6 - 4.5
6 - 4 - 0.5
2 - 0.5
(1.5, -2)
The midpoint of segment RS is (1.5, -2).
