Kurt says factors and multiples are related. Use the equation 8×5 = 40 to describe the relationship between factors and multiples.
Answer:
Before heading towards the solution, you need to make sure how multiple and factors are related to each other.
The multiple of a number could be obtained by multiply it with another number.
For example, the first five multiples of 12 are 12, 24, 36, 48 and 60
1 X 12 = 12
2 X 12 = 24
3 X 12 = 36
4 X 12 = 48
5 X 12 = 60
Factors are the numbers that are multiplied to get a given number.
For example,
1 X 12 = 12
2 X 12 = 24
3 X 12 = 36
The factors of 12 are 1, 2, 3, 4, 6 and 12.
As division and multiplication can be used to find factors and multiples.
For example a whole number is a multiple of its factors.
Let w = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} be the set of even wholes numbers from 2 to 20.
As 2 is a factor of 20 because 20 ÷ 2 = 4
20 is a multiple of 2 because 2 X 10 = 20
So, in the same way, the equation 8 X 5 = 40 can be used to determine how factors and multiples are related.
Let the equation be
8 X 5 = 40
8 is a factor of 40 because 8 X 5 = 40
40 is a multiple of 8 because 40 ÷ 5 = 8
So, this is how factors and multiples are related to each other.

(-3,10) and (-3,6) find the slope pleassseeee !!!
Answer:
the slope is undeifined
hope this helps :)
Answer:
undefined
Step-by-step explanation:
the formula for the slope of a line is m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
m = (6-10)/(-3+3) = -4/0 = undefined, you cannot divide by zero.
write an equation of the line in slope-intercept form slope 1 and y intercept -8

Akira and Hideo are twins with different jobs. Akira earns five-eighths of what Hideo earns, but Akira's expenses are half of Hideo's. Akira ends up saving 40% of his income. What percentage of his income does Hideo save?
Answer:
25%
Step-by-step explanation:
Let x represent Akira income and let y represent Hideo income.
Since Akira earns five-eighths of what Hideo earns, therefore Akira income is given by:
x = (5/8)y
Let a represent Akira expenses and let y represent Hideo expenses. Since Akira expenses is half of Hideo, hence:
a = (1/2)b; b = 2a
Given that Akira savings is 40% of his income, we have:
savings = income - expenses
40% of x = x - a
a = x - 0.4x
a = 0.6x
For Hideo:
Income = y, expenses = b = 2a
Savings = income - expenses
Savings = y - 2a
Savings = y - 2(0.6x) = y - 1.2x
Savings = y - 1.2(5/8)y
saving = y - 6y/8
savings = 2y/8 = 0.25y
Therefore Hideo saves 25% of his income
a collector purchased a rare book for $97.56 and then sold the book in an online auction for $141.82. The auction charged the collector $8.25 in fees for the use of its service. how much did the collector earn by selling the book
Answer:
$36.01
Step-by-step explanation:
141.82 - 8.25 = 133.57
133.57-97.56=36.01
The collector earned a total of $36.01 by selling the book.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
The collector earned $141.82 - $97.56 = $44.26 by selling the book.
To find the total amount the collector earned, we need to subtract the price they paid for the book from the price they sold it for. This gives us the profit that the collector made on the sale of the book.
However, we also need to subtract the auction fees that the collector had to pay.
The collector paid $8.25 in fees, so their total earnings from the sale of the book were :
⇒ $44.26 - $8.25
Apply the subtraction operation, and we get
⇒ $36.01.
Therefore, the collector made a total of $36.01.

-3(2+6x) +7x
Answer:
x = -17
Step-by-step explanation:
To simplify, we need to solve within the parentheses first:
-3(2 + 6x) + 7x
(-6 - 18x) + 7x
Next, we combine like terms:
-6 - 18x + 7x
-6 - 11x
Next, we isolate the variable "x":
-6 - 11x
/x
-6 - 11 = x
Combine like terms:
x = -17

Bryans gocket team is purchasing jersys. The company charges $250 for the onetime set-up fee and $23 for each printed jersey which expression repressents the total cost of x number for the team
Given:
The company charges $250 for the onetime set-up fee and $23 for each printed jersey.
To find:
The expression that represents the total cost of x number for the team.
Solution:
We have,
Fixed charges = $250
Additional charges = $23 per printed jersey
Let x be the number of printed jersey. Then,
Additional charges = $23x
Total chargers = Fixed charges + Additional charges
= $(250 + 23x)
Therefore, the expression for the total charges is $(250 + 23x).

Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°
Answer:
Step-by-step explanation:
x=5
y=-5
Hence it lies in 4th quadrant.
x=r cos θ
5=r cos θ ...(1)
y=r sin θ
-5 =r sin θ ... (2)
square and add
(5)²+(-5)²=r²(sin ²θ +cos ²θ )
r²=25+25=50
r=±5√2
dividing
tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)
θ=135°,315°
so polar coordinates are (5√2,315°) and (-5√2,135°)
