Answer:
c-43=47
Step-by-step explanation:
Well this is kinda obvious.
He already sold 43 cups of hot choclate and he needed 47 more.
So the total amount of cups is (c) so we can make an equation like this
c-43 (since theres total which is unknown so ”c” and then Theres the already sold 43 cups).
c-43=47 (the 47 is the amount he needs to sell)
So final equation to determine total cups needed
c-43=47

Answer:
Step-by-step explanation:
38,500-36,000=2,500
B. The difference in the starting salaries is $2,500.
D. Luisa will make more money in the first 8 years.
The required scenario are,
(1) The difference in the starting salaries is $2,500.
(2) Damon will make more money in the first 8 years.
Given that,
Luisa took a job in which her salary can be modeled by the exponential function y = 36.000(1.025)", where x is the number of years after she is hired. Damon took a job with a starting salary of $38.500 and yearly raises of $800.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
According to the question,
Difference in starting salary = 38500 - 36000 = $2500
Luisa's salary after 8 years = $43862.50
Damon's salary after 8 years = $45108.89
Thus, the required scenario is,
(1) The difference in the starting salaries is $2,500.
(2) Damon will make more money in the first 8 years.

please explain how to use cancellation method with examples. I'm really confused...
Answer:
Cancellation it enables us to eliminate or get rid of one of the variables, so we can solve a more simplified equation.
Some textbooks refer to the elimination method as the addition method or the method of linear combination.
This is because we are going to combine two equations with addition!
Step 1
First, we align each equation so that like variables are organized into columns.
Step 2
Second, we eliminate a variable.
If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.
Step 3
Thirdly, we substitute this value back into one of the original equations and solve for the other variable.
Example of how to apply the elimination method for solving systems of equations is attached.
Nadia drew a square in her notebook Each side measured 2.5 centimeters
Answer:
The perimeter of the square is 10 cm.
The area of the square is 6.25 cm.
Step-by-step explanation:
To find perimeter, add all the sides.
2.5 + 2.5 + 2.5 + 2.5 = 10
To find area, multiply the length by the width. Since Nadia drew a square, all the sides will have the same measurement (2.5 cm, in this case). So, simply multiply 2.5 by 2.5, knowing that the length and width of the square are the same size.
2.5 × 2.5 = 6.25
The area of Square is 6.25 cm² and Perimeter of Square is 10 cm.
what is Area and Perimeter of Square?The Area of Square is the product if its side
i.e., Area of square = side x side
and, perimeter of square = 4 x side
Given:
Side of Square= 2.5 cm
then , area of Square= side x side
= 2.5 x 2.5
= 6.25 cm²
and, Perimeter of Square= 4 x side
= 4 x 2.5
= 10 cm

and then the 3 ounces for yourself so 8 ounces taken away
20 - 8 = 1212 ounces leftThe line segment, AB has a point C as its midpoint. If A is at (2,2) and C is at (5,4) what are the coordinates of the endpoint B
A:(-1,0)
B:(3.5,3)
C:(5,4)
D:(8,6)
Answer:
( 8 , 6 )
Step-by-step explanation:
A = ( 2 , 2 ) and C = ( 5 , 4 )
→ Form an equation

+ 16
h =
Answer:
h=3/4
Step-by-step explanation:
19=h4+16
19-16=h4+16-16
3=h4
3/4=h4/4
3/4=h
h=3/4
Answer:
h = 3/4 or as a decimal it would be 0.75
Step-by-step explanation:
19 = h × 4 + 16
Reorder the terms
Use the communative property to reorder the terms
19 = 4h + 16
19 = 4h + 16
Move the terms
Move the variable to the left - hand side and change its side
19 - 4h = 16
Move the constant to the right - hand side and change its sign
-4h = 16 - 19
-4h = 16 - 19
Calculate
calculate the difference of 16 minus 19
-4h = -3
-4h = -3
Divide both sides of the eqaution by -4
Therefore your answer is h = 3/4 or if you want a decimal simplify 3/4 by dividing 3 and 4, which gives you 0.75
A duck dives underwater and its path is described by the quadratic function y = 2x^2 - 4x, where y represents the position of the duck in meters and x represents the time in seconds. How long was the duck underwater?
Solving the quadratic equation, it is found that the duck was underwater for two seconds.
The path of the duck after x seconds is modeled by:
[tex]y = 2x^2 - 4x[/tex]
It is a concave up parabola, thus, the negative values of y, when he is underwater, are between the roots.
To find the roots:
[tex]y = 0[/tex]
[tex]2x^2 - 4x = 0[/tex]
[tex]2x(x - 2) = 0[/tex]
[tex]2x = 0 \rightarrow x = 0[/tex]
[tex]x - 2 = 0 \rightarrow x = 2[/tex]
2 - 0 = 2, thus, the duck was underwater for two seconds.

HELP.....................
Let me first ask this :
how do u find the midnumber of 1 and 3 ?
( 1 + 3 ) ÷ 2 =
4 ÷ 2 =
2
_________________________________
It is the exact way we do to find the midpoint of a line ; have a look :
The midpoint of AB is P thus :
( Point A + Point B ) ÷ 2 = Point P
Suppose that we have point B as ( x , y ) then :
[ ( 2 , 3 ) + ( x , y ) ] ÷ 2 = ( 6 , - 1 )
Now we add the same components of points A and B together, that is, we add the first component A to the first component B and replace the first component, and so we add the second component A to the second component B. And replace the second component :
[ ( 2 + x , 3 + y ) ] ÷ 2 = ( 6 , - 1 )
( 2 + x/2 , 3 + y/2 ) = ( 6 , - 1 )
Well now we have a draw so the first components of both sides of the draw must be equal Also, the second components of the two sides of the equation must be equal , thus :
2 + x/2 = 6
Multiply both sides by 2
2 × ( 2 + x )/2 = 2 × 6
2 + x = 12
Subtract both sides 2
2 - 2 + x = 12 - 2
x = 10 &3 + y/2 = - 1
Multiply both sides by 2
2 × ( 3 + y )/2 = 2 × ( - 1 )
3 + y = - 2
Subtract both sides 3
3 - 3 + y = - 2 - 3
y = - 5________________________________
And finally, after all the hardship and misery, we realized that
B = ( 10 , - 5 )Which mean Option C is the correct answer.
