The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the ________property of multiplication.
Answer:
The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the Commutative property of multiplication.
Step-by-step explanation:
Commutative property is A × B = B × A
So the equation 4 ∙ 5 = 5 ∙ 4 is same as commutative property
Answer:
The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the commutative property of multiplication.
Step-by-step explanation:
The commutative property means that the positions of the numbers on each side of the equation can be swapped and both sides would be equal.
You can think of it as A x B = B x A
Suppose you need to put a fence around a rectangular garden that has a perimeter of 64ft. The width is 12ft less than the length. Find the width and length of the garden.
Answer:
x=length
x-12=width
you techinally have to count 2 lengths and 2 widths.
2x + 2x - 24= 64
4x = 88
x = 22
so the length is 22 and the width is 10

19. Helen has 2 more than twice as many stamps as Gail. If Gail
buys 10 more stamps, she and Helen will have the same
number of stamps. How many stamps does each person have
now?
Answer:
x(Gail)=8 and y(Helen)=18
Step-by-step explanation:
2x+2=y and x+10=y
Plug y in and solve for x
2x+2=(x+10)
2x-x=10-2
x=8
Plug x in and solve for y
(8)+10=y
y=18

Step-by-step explanation:
[tex]77^\frac{1}{10}[/tex] is the same as [tex]\sqrt[10]{77^1} ,[/tex] or simply [tex]\sqrt[10]{77}[/tex]
77^1/10 can be written as [tex]\sqrt[10]{77}[/tex]
what is representation of root?The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.
A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.
We have that [tex]77 ^ {1/10}[/tex].
Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]
Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]
Similarly we can write 77^1/10 as [tex]\sqrt[10]{77}[/tex]

you verified that the solution is correct.
–5(1 – 5x) + 5(–8x - 2) = -4x – 8x
Answer: x = -5
-------------------------------------------------------------------------------------------------------------
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(1−5x)+5(−8x−2)=−4x−8x
-------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the equation.
−5(1−5x)+5(−8x−2)=−4x−8x
(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)
−5+25x+−40x+−10=−4x+−8x
(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)
−15x+−15=−12x
−15x−15=−12x
-------------------------------------------------------------------------------------------------------------
Step 2: Add 12x to both sides.
−15x−15+12x=−12x+12x
−3x−15=0
-------------------------------------------------------------------------------------------------------------
Step 3: Add 15 to both sides.
−3x−15+15=0+15
−3x=15
-------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by -3.
−3x /−3 = 15/ −3
x=−5

n, find the value of x and y.
35°
Answer:
x = 145, y = 35
Step-by-step explanation:
so y is equal to 35 because alternate interior angles are equal to each other (you can search this up if you're confused) and x = 145 because of supplementary angles so I did 180 - 35 = 145. hope this helps!

Determine the equation of this line, pitting your answer in the form Ax + By + C = 0, where A B C are intergers.
Answer:
5x + 4y - 20 = 0
Step-by-step explanation:
1. Find the two points given: (0,5) and (4,0)
2. Find the slope of the line:
m = [tex]\frac{5-0}{0-4} = \frac{-5}{4}[/tex]
3. Find y intercept by plugging in one point into the y-intercept form
y = (-5/4) x + b
0 = (-5/4) (4) + b
b = 5
4. Write out the equation in y-intercept form
y = (-5/4) x + 5
5. Rewrite it in Ax + By + C = 0 form
(5/4) x + y - 5 = 0
6. Since A B C all need to be integers, multiply the whole equation by 4
5x + 4y - 20 = 0
