Megan buys 5 boxes of cookies for $3.75 each. What is her change from $20.00? Explain your answer.
Answer:
$1.25
Step-by-step explanation:
3.75 x 5 = 18.75
20-18.75 = 1.25
Answer: $1.25
Step-by-step explanation: Megan bought five boxes of cookies. Each box is $3.75. Multiply $3.75 by 5. Your answer is $18.75.
She has $20. Subtract $20.00 minus $18.75.
Her change is $1.25.

Carl makes $18.50 for every two hours of work. The constant of proportionality for this relationship is $________ per hour
Answer:
$9.25 per hour
Step-by-step explanation:
So we know that the question is asking for how much Carl makes per hour, but what we do know is that he makes $18.50 every 2 hours. Therefore, you want to divide $18.50 by 2 because you want that 2 to become a 1. Here is what it looks like as an equation:
Step 1) $18.50 = 2x
divide both sides by 2 to leave x on its own.
Step 2) $9.25 = x
Hope this helps! :)
Answer: 9.25 per hour

what are reasons A and B in the proof?
A. Distributive Property
B. Commutative Property of Multiplication
C. Associative Property of Multiplication
D. Multiplication
The reason A is the cumulative property of multiplication and the reason B is multiplication.
What is the cumulative property of multiplication?This law merely asserts that while adding and multiplying integers, you can rearrange the numbers in a problem without changing the solution.
Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.
The given expression A 12[J.(2.3).k] is showing the cumulative property.
The expression B ( 12.6).jk is showing the property of multiplication.
Therefore, the cumulative feature of the above expression A 12[J.(2.3).k] is evident. The property of multiplication is demonstrated by the formula B (12.6).jk.

Answer:
Step-by-step explanation:
Using CPCT rule in triangle we got ∠CBD ≅ ∠ DEC. Hence, proved.
Given that, in ΔCAD B is on AC, E is on AD, AC = AD and AB = AE.
What are congruent shapes?Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same. To do this we need to check all the angles and all the sides of the shapes. If two shapes are congruent they will fit exactly on top of one another.
We need to prove ∠CBD ≅ ∠ DEC.
It is given that AC=AD, so ΔCAD is isosceles triangle, then ∠ACD=∠ADC.
Now, consider ΔBCD and ΔCED.
AC-AB=AD-AE (∵AB=AE)
So, BC=DE
DC=CD (common side)
∠BCD=∠EDC (Derived)
Therefore, by SAS congruency ΔBCD ≅ ΔCED.
Using CPCT rule in triangle we got ∠CBD ≅ ∠ DEC. Hence, proved.

What is the minimum angle of rotation (in degrees) that will carry the star onto itself?
Answer:
Minimum angle = 108°
Step-by-step explanation:
From the figure attached,
Minimum angle to overlap the star onto itself is the angle of rotation from point A to B.
Let the angle between A and B measure a°.
If we complete a star pentagon by joining the vertices of the star,
Formula to measure the internal angle of a polygon is,
Measure of internal angle = [tex]180\times \frac{(n-2)}{n}[/tex]
Measure of ∠ABC = [tex]\frac{(5-2)}{5}\times 180[/tex]
= 108°
Since, one side star divides the interior angle into three equal parts,
Measure of interior angle = [tex]\frac{108}{3}[/tex] = 36°
From ΔAOB,
m(∠OAB) + m(∠AOB) + m(∠ABO) = 180° [Sum of interior angles of a triangle = 180°]
36° + a + 36° = 180°
a + 72° = 180°
a = 180 - 72
a = 108°
Therefore, by the minimum angle of rotation of 108° star will overlap onto itself.
Explain how rigid transformations can be congruent.
Step-by-step explanation:
The three types of Rigid Transformations are Reflection, Rotation, and Translation.
Congruent means equal in all lengths, size and shape.
Rigid transformations are always congruent (or equal) because they never change their form, size or shape. They will always be the same shape and size no matter when it is moved.
They can be congruent when the shape is not different from the original, same size, same length/width, same form.
Dilation is NOT part of a rigid transformation because it widens or decreases its size/shape.

DONE
For
Answer:
The equations in the slope-intercept form
y = - 2 x + 5
y = - 2 x + 3
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the line.b is the y-intercept.To put any equation in the slope-intercept form state y on the left side, x and the numerical term on the right side, the coefficient of y must be 1.
Let us do that with the given equations
∵ 2x + y = 5
→ Subtract 2x from both sides to move x to the right sides
∴ 2x - 2x + y = 5 - 2x
∴ y = 5 - 2x
→ Switch 5 and - 2x
∴ y = - 2x + 5
∵ 3y = 9 - 6x
→ Divide each term by 3 to make the coefficient of y = 1
∴ [tex]\frac{3y}{3}=\frac{9}{3}-\frac{6x}{3}[/tex]
∴ y = 3 - 2x
→ Switch 3 and - 2x
∴ y = - 2x + 3
The equations in the slope-intercept form
y = - 2x + 5
y = - 2x + 3
Answer:
Write each equation in slope-intercept form.
y = -2x + 5
y = -2x + 3
What do the equations have in common? How are they different?
- The slopes are the same.
- The y-intercepts are different.
The system represents lines that (are parallel),
therefore the system has no solution.

A portrait without its frame has a height of 2.5 times its width w, in inches. Its frame is 2 in. Wide all along its perimeter. What is an expression for the area of the framed portrait in terms of w? Simplify your expression & write it in standard form. Fill in the blanks:
Answer:
2.5w² + 14w + 16
Step-by-step explanation:
Width of portrait without frame = w
Height of portrait without frame = 2.5*w = 2.5w
Given that the portrait has a frame that is 2 in wide all along its borders, therefore,
Width of framed portrait = w + 2 + 2 = w + 4
Height of framed portrait = 2.5w + 2 + 2 = 2.5w + 4
Expression of the area of the framed portrait in terms of w = (w + 4)(2.5w + 4)
Simplify and express in standard form as follows:
Area = (w + 4)(2.5w + 4)
Apply the distributive property of multiplication
w(2.5w + 4) +4(2.5w + 4)
2.5w² + 4w + 10w + 16
Combine like terms
Area = 2.5w² + 14w + 16

5m-3/63 = 9/21 solve for m
Answer:
m=10.5
Step-by-step explanation:
First, add 3/63 on both sides to get 5m by itself.
5m-3/63 = 9/21
+3/63 +3/63
(9/21 x 3 = 27/63)
5m = 30/63
Simplify.
5m = 10/21
To get m by itself, divide 5...
5m = 10/21
/5 /5
Multiply by the reciprocal.
5x21/10
m=10.5
I hope this helps you out! Have an amazing day c:

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
5m - ( 3/63 ) = ( 9/21 ) be equation (1)
On simplifying the equation , we get
5m - ( 1/21 ) = ( 9/21 )
Adding 1/21 on both sides of the equation , we get
5m = ( 9/21 ) + ( 1/21 )
Now , on further simplification , we get
5m = 10/21
Divide by 6 on both sides of the equation , we get
m = ( 10/21 ) / 5
m = 2/21
Therefore , the value of m is 2/21
Hence , the equation is m = 2/21

solve equation 7-5c=17+5z
Answer:
Solving for C? Well
7 - 5c = 17 + 5z
-5c = 10 + 5z
c = (10 + 5z) / -5 = -2 - z
c = -z - 2 :)
Answer:
Step-by-step explanation:
mark the term with the c variable on one side of the equation.
so you'll get
-5c = 17 + 5z - 7
-5c = 10 - 5z
(divide whole equation by -5 now)
c = -2 + z
or
c = z-2
