1/5 ÷ 2
Explain how you could use multiplication to help check your answer to Number 1
Answer:
1/10
Step-by-step explanation:
you can find the reciprocal of 2 (which is 1/2) and multiply it to 1/5 and get 1/10, that is your answer
I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!
Answer:
1/10
Step-by-step explanation:
You first divide and then divide just becomes multiplication(I know its weird)
K(Keep) C(Change) F(Flip)
(1/5 ) (division becomes) x (The whole number 2 becomes the recipicol 1/2)
Then you multiply 1/5 times 1/2 =1/10
The table shows the relationship between the amount of candy bought (in pounds) and the total cost of the candy (in dollars) (5 points) Amount of Candy (pounds) 1 2 3 4 5 Cost (dollars) 65 120 195 220 300 Part A – Answer the question - Is cost proportional to pounds of candy bought? Why or why not? (You MUST show work to receive full credit!) Part B - – Write an equation to represent the relationship. The formula for the equation is y = kx
Answer:
65
Step-by-step explanation:
Answer:
(cost) is proportional to (amount of candy) because all of the values of the
ratios comparing cost to pounds are equivalent. All of the values of the ratios
are equal to . Therefore, every measure of (amount of candy) can be
multiplied by the number to get each corresponding measure of (cost).

Answer:
5z^2-8z+3
-5×-3=15
-5+-3=-8
so...
5z^2-5z-3z+3
5z(z-1)-3(z-1)
therefore the answer is...
(5z-3) (z-1)
10 + 3x= 5 – 2x
What are the steps to finding the answer
Answer:
x=-1
Step-by-step explanation:
10+3x=5-2x (Add 2x to both sides)
10+5x=5 (Subtract 10 from both sides)
5x=-5 (Divide both side by 5)
x=-1
Answer:
x=-1
Step-by-step explanation:
10 + 3x= 5 – 2x
You first +2x on both sides
10 + 3x+2x= 5 – 2x+2x
subtract 10 on both sides
10-10+5x=5-10
Then divide 5 to isolate x
5 divide 5x=-5 divide 5
x=-1
Hope that helps :)

2x – 3y < -12
Answer:ok....
Step-by-step explanation:
1)Identify the conjugate for 6 – 7√3 and explain your reasoning.
2)Multiply the radical expression 6 – 7√3 and its conjugate and write in simplified form. Show all your steps
3) Explain why we always get an integer when multiplying a radical expression by its conjugate? Provide your own appropriate example with supporting work that matches your explanation..
Answer:
1) The conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].
2) -111
3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.
Step-by-step explanation:
1) A radical number of the form [tex]r = a + b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], where the first component is a non-radical real number which acts as a "pivot" and the second component is the radical component, which generates a "displacement" from pivot.
The conjugate of [tex]r[/tex] is a real number [tex]s = a - b\sqrt{c}[/tex], [tex]\forall \,a,b,c\in \mathbb{R}[/tex], which that is "pivot" plus "displacement" in the direction opposite to that of [tex]r[/tex]. We proceed to complement this explanation with the image attached below.
Then, the conjugate for [tex]6-7\cdot \sqrt{3}[/tex] is [tex]6+7\cdot \sqrt{3}[/tex].
2) We proceed to performed all the need algebraic operation until result is found:
1) [tex](6+7\sqrt{3})\cdot (6-7\sqrt{3})[/tex] Given
2) [tex]6\cdot (6-7\sqrt{3})+7\sqrt{3}\cdot (6-7\sqrt{3})[/tex] Distributive property
3) [tex]6\cdot [6+(-7)\cdot \sqrt{3}]+7\cdot \sqrt{3}\cdot [6+(-7)\cdot \sqrt{3}][/tex] Definition of subtraction/ [tex]-a\cdot b = (-a)\cdot b[/tex]
4) [tex]6\cdot 6 +[6\cdot (-7)]\cdot \sqrt{3}+(6\cdot 7)\cdot \sqrt{3}+[7\cdot (-7)]\cdot (\sqrt{3}\cdot \sqrt{3})[/tex] Distributive, associative and commutative properties
5) [tex]36 +(-42)\cdot \sqrt{3}+42\cdot \sqrt{3}+(-49)\cdot 3[/tex] Definition of multiplication/[tex]-a\cdot b = (-a)\cdot b[/tex]/Definition of square root
6) [tex][36 +(-147)]+\sqrt{3}\cdot [42+(-42)][/tex] Commutative, associative and distributive properties/[tex]-a\cdot b = (-a)\cdot b[/tex]
7) [tex]-111+\sqrt{3}\cdot 0[/tex] Definition of subtraction/Existence of additive inverse
8) [tex]-111+0[/tex] [tex]a\cdot 0 = 0[/tex]
9) [tex]-111[/tex] Modulative property/Result
3) It is because number and its conjugate have the same numbers but their second components are opposite to each other.

Help plz anyone who’s good with slope?
Answer:
-3
Step-by-step explanation:
you go down from the dot left most and you count towards the line that the second dot falls on and count over too it
Answer:
slope = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m = [tex]\frac{-1-2}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3

Pleaseeeeee help this is due today and I don’t know how to do thissss! Tug of War Activity
DIRECTIONS: Use the information provided about the first two rounds to figure out who will win the remaining rounds of the Tug of War.
Round 1:
On one side of the rope, there are four acrobats who all have equal strength. On the other side are five grandmas who each have equal strength as well. The result of the tug of war is dead even-- it’s a perfect tie.
Round 2:
On one side is Ivan the dog. On the other side are two grandmas and one acrobat. Again, it is dead even-- a perfect tie.
Round 3:
Three grandmas and Ivan are pulling against four acrobats. Which team wins? Justify your answer with at least 2 sentences.
Round 4:
Ivan and three acrobats are matched up against a team of grandmas. The result is a tie-- the two sides are evenly matched. How many grandmas were on the team? Explain your reasoning.
Bonus Round 5:
Create two teams of your choice in Round 5 that are not equally matched. Use Ivan and at least one acrobat and one grandma on either team. Explain which side will win and how you know.

Solve 5(y - 10) = -5
Answer:
y = 9
Step-by-step explanation:
Trying to get the variable alone is the main goal in solving these
to get the variable alone here we can divide both sides by 5, which gets us
y - 10 = -1
now we can add 10 to both sides to get y = 9

Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 1) ← 2 points on the line
m = [tex]\frac{1-0}{0-(-2)}[/tex] = [tex]\frac{1}{0+2}[/tex] = [tex]\frac{1}{2}[/tex]

Thank you so much !!
Answer:
Y = 8
Step-by-step explanation:
7- -1 is 8. If you're subtracting a negative, you're basically adding.
So 7+1 is 8.
Jaylen earns the same amount of money each month. His telephone bill is 1 20 of his monthly earnings, and he pays a total of $840 each year for his telephone service. How much does Jaylen earn each month, in dollars? Do not include commas or dollar signs.
Given :
Jaylen earns the same amount of money each month.
His telephone bill is 1/20 of his monthly earnings, and he pays a total of $840 each year for his telephone service.
To Find :
How much does Jaylen earn each month, in dollars.
Solution :
Monthly payment of telephone bill is :
[tex]M = \$ \dfrac{840}{12}\\\\M = \$70[/tex]
Let, his monthly salary is A.
So,
[tex]M = \dfrac{A}{20}\\\\A = 20\times M\\\\A = 20 \times 70\\\\A = \$1400[/tex]
Therefore, Jaylen monthly income is $1400.
put them in the order from least to greatest. You can use the number line to help.

Find the value of 3a + 2b -3 when a=-5 and b=-6
Answer:
-30
Step-by-step explanation:
Substituting values of a and b in equation
3(-5)+2(-6)-3
-15-12-3
-15-15
-30
Answer: -30.
Step-by-step explanation:
We start by multiplying 3 by -5 and 2 by -6.
So the new equation will be [tex]-15-12-3[/tex].
Then, we can either minus -12 by -3 or we can minus -15 by -12. Either way, we get the right answer.
[tex]-15-12=-27[/tex]
Then, the new equation will be [tex]-27-3[/tex].
[tex]-27-3 = -30[/tex].
Answer: [tex]-30[/tex].
