Answer: we are simply to subtract the length of the gold ribbon which is 2 4/6 ft from the length of the silver ribbon, 5 2/6 feet. Mathematically,
5 2/6 feet - 2 4/6 feet = 8/3 feet
Therefore, Gina has 8/3 feet more of the silver ribbon than the golden ribbon.

Fill in the blanks below so the answer is x = 3
X +
= 10
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

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.
A gardening store ordered 222,840 potted plants last year. This year, the store ordered 5% more than that number. How many potted plants were ordered this year?

222840+11,142= 233,982
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°
Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.
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.
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).
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.

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

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 $

Find the area of each sector. Round your answers to the nearest tenth.
Answer:
Area of sector = 102.6 feet squared
Step-by-step explanation:
Given:
Radius of circle = 14 ft
Angle θ = 60°
Find:
Area of sector
Computation:
Area of sector = [θ/360]πr²
Area of sector = [60/360](22/7)(14)²
Area of sector = [1/6][22/7][196]
Area of sector = 102.6 feet squared
Your test in math class has problems worth 2 points and problems worth 4 points. Altogether the
test has 100 points. Write an equation that represents the total points on the test formed by the
number of 2-point problems and the number of 4-point problems
Labels: x= Click here
y= Click here
A
Write an equation in standard form
Click here
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

Multiply: (3x - 5)(-x + 4)
Applying the distributive property, the expression becomes (3x)(-x) + (3x)(4) + (-5)(-x) + (-5)(4).
What is the simplified product in standard form?
Answer:
-3x²+17x-20
Step-by-step explanation:
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.
(3x)(-x)=-3x²
+
(3x)(4)=12x
+
(-5)(-x)=5x
+
(-5)(4)=-20
Add those and you will get your answer. Hope this helped :)
