While shopping, Dawn finds a backpack that she likes on the sale rack. Its original price is $60,
but everything on the rack comes with a 30% discount. Dawn also has a coupon for 15% off of
her total purchase.
Dawn says, "Thirty percent and fifteen percent make forty-five percent and 45% of $60 is $33,
so it will cost $33."
Is Dawn correct? Explain why or why not. Be sure to support your reasoning with a
mathematical model.
No. Because 33 $ is the money deducted from the 60 $. Dawn bought everything for less than 60 $.
So, if Dawn purchases everything on the rack with a 30% discount and 15% coupon the total will indeed make 45%.
We have to take 100% - 45%= 55% to know the reduction number. Let's proceed to the calculations now.
100%= 60 $
1%=60/100
55%= 60/100 × 55 = 33 $
Now NOTE; 33 $ is the money reduced from the 60 $. So, logically, 33 $ isn't the amount which Dawn purchased the whole rack.
To find the amount at which she purchased everything, we need to do,
60 $ - 33 $ = 27 $

How many 4 point problems are on the test if there are 32 2 points questions? Click here
Answer:
Equation: 100 = 2x + 4y
There are 9 4 points problems
Step-by-step explanation:
In this case, we know that we have a test that in total, we must sum 100 points. This could be with question of 2 points or questions of 4 points.
We do not know exactly how many questions of 2 or 4 point are, but we can write an equation that could give us an idea.
Let's call "x" the number of questions worth 2 points.
Let's call "y" the number of questions worth 4 points.
All together must give 100 points, therefore, the logic equation to do this is:
100 = 2x + 4yNow, for the second part of this problem, we want to know how many 4 points problems would be in the test if we have 32 questions of 2 points. For that, we use the above equation, and solve for y:
100 = 2(32) + 4y
100 = 64 + 4y
100 - 64 = 4y
36 = 4y
y = 9Hope this helps

Answer:
-3x²+17x-20

When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.

Consider the diagram and angle measures shown below What is the value of m angle 3 ?
Answer:
The answer is below
Step-by-step explanation:
m∠lon = m∠2 (vertical opposite angles are equal)
m∠lon = m∠1 (corresponding angles are equal).
Therefore; m∠2 = m∠1 (substitution property)
3x + 25 = 7x + 5
Subtracting 5 and 3x from both sides of the equation:
3x + 25 - 5 - 3x = 7x + 5 - 5 - 3x
4x = 20
dividing through by 4:
4x / 4 = 20 / 4
x = 5
Given that:
m∠3 = -2x + 70
substituting x = 5:
m∠3 = -2(5) + 70 = 60
m∠3 = 60°
Therefore:
m∠4 + m∠2 + m∠3 = 180° (substitution)
(155 - 3x) + (7x + 5) + (-2x + 70) = 180
(-3x + 7x - 2x) + (155 + 5 + 70) = 180
2x + 230 = 180
2x = -50
x = -25
Therefore; m∠3 = -2x + 70 = -2(-25) + 70 = 50 + 70
m∠3 = 120°

Help please I’m in a test rn btw
Answer:
3 and 1
Step-by-step explanation:
To make this equation true you have to fill in the blank spots so x is 3
So I simply multiplied 3 times x which is 3x+ blank is 10
if I want x to be 3 then I fill in the blank for 1
now I do additive inverse to get the x by itself
subtract 1 on both sides
the equation is now 3x=9
Divide 3 in each sides and x=3
Answer:
1x + 7 = 10
-4x + 22 = 10
Step-by-step explanation:
Equations
We are given the following expression:
__x + __ = 10
Where the spaces must be filled with any value that makes x=3 the solution to the equation.
Let's call a and b the variables to fill up the spaces:
ax + b = 10
For x=3, the following equation must stand:
3a + b = 10
Any combination of a and b that makes true the above equation will solve the problem. Let's solve for b:
b = 10 - 3a
Make a=1, thus b = 10 - 3 = 7
So the equation:
1x + 7 = 10
Has the solution x=3
For a = -4, b = 10+12 = 22
Another combination is:
-4x + 22 = 10

A parallelogram has an area of x2 + 9x - 36.
a. What are expressions for the length and width of the parallelogram?
b. If x is an integer, what is the least possible value of x for a parallelogram
to exist? Explain.
Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentiation:
A = x^2 + 9x - 36. This factors into A = (x + 12)(x - 3). We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.
Note that if x = 3 the area becomes zero. So: x must be greater than 3, so that the (x - 3) factor is positive.
Example: If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.

Solve. {3d−e=7 d+e=5 Use the linear combination method. The solution is (2, −1). There are infinitely many solutions. The solution is (3, 2). There is no solution.
Answer:
The solution of the given equations are (3,2).
Step-by-step explanation:
Given equations are :
3d−e=7 ...(1)
d+e=5 ...(2)
Add equations (1) and (2) we get :
3d-e+d+e=7+5
4d = 12
d = 3
Put the value of d in equation (2).
3+e=5
e = 2
So, the value of d = 3 and e = 2. Solution of the given equations are (3,2).

The area of the circle will be 3.14 feet .
Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.
Answer:-★Given,
→ Diameter = 2 feet
→ Circumference = 2/2 = 1 feet
★Now,
→Area of a circle = πr²
→ = 3.14 × 1 × 1
→ = 3.14 feet
Hence , the circumference is 3.14 feet.
If you add Natalie's age and Fred's age, the result is 40. If you add Fred's age to 4 timesNatalie's age, the result is 76. Write and solve a system of equations to find how old Fred and Natalie are.
Answer:
Natalie is 12 years and Fred is 28 years
Step-by-step explanation:
lets assume Natalie's age is X and Fred's age is Y
From the first sentence: X+Y = 40
From the second sentence: Y + 4X = 76
lets rearrange the equations
X+Y =40 ....... equation 1
4X+Y=76........ equation 2
To solve both equations, we will have to look for a way to eliminate one of the unknown to leave us with one unknown. since there are two +Y in both equations, we can subtract both equations to eliminate Y. Please note that whatever you do to one of the unknown in this equations applies to all other numbers & alphabets
So: 1. X - 4X = -3X
2. Y - Y = 0
3. 40 -76 = -36
writing the equation as one will be -3X = -36
X = 12
Put X = 12 into any of the equation
By putting X as 12 into equation 1 : 12 + Y = 40
Y = 40 -12 =28
Recall that Natalie is X and Fred is Y
Therefore Natalie is 12 years and Fred is 28 years
be
To crosscheck put in the gotten answers into the equations
X+Y =40 ....... 12 + 28 = 40
4X+Y=76........ 4(12) + 28 = 76

Ally the turtle was born with 1 square on her shell, as in the first picture below. When she was 1 year old, 8
new squares appeared around the old squares, as in the second picture below. Each year, a new group of
squares appeared around the old squares.
How many new squares appeared on Ally's shell each year? Extend the pattern and fill in the blanks in the
chart below.
Answer:
2=16 3=24 spot on her shell
Step-by-step explanation:
The number of squares appeared on Ally's shell at the age of 2 is 64 and the age of 3 is 512.
What is a Square ?"A square is a two-dimensional plane figure with four equal sides and all the four angles are equal to 90 degrees. The properties of rectangle are somewhat similar to a square, but the difference between the two is, a rectangle has only its opposite sides equal. Therefore, a rectangle is called a square only if all its four sides are of equal length."
Given,
When the turtle was 1 year old the number of squares = 8
When the turtle was 2 year old the number of squares = 8 * 8 = 64
When the turtle was 3 year old the number of squares = 64 * 8 = 512
Hence, square at age 1 = 8, squares at age 2 = 64, squares at age 3 = 512.

The system of equations is graphed on the coordinate plane.
y=-5/3x+3
y=1/3x - 3
Enter the coordinates of the solution to the system of equations
in the boxes.
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.
