Explanation:
7+6 = 13. Divide this over 5 to get 13/5 = 2 remainder 3. The quotient 2 is something we don't care about. We only worry about the remainder. Therefore 7+6 = 3 (mod 5)
-------------
2+1 = 3 (mod 5) for similar reasoning as above. 3/5 = 0 remainder 3.
-------------
20 = 9 (mod 11) since 20/11 = 1 remainder 9. Imagine you had 20 cookies and 11 friends. Each friend would get 1 whole cookie (quotient) and there could be 9 left over (remainder).
-------------
35/11 = 3 remainder 2
Or you could use repeated subtraction like so to find the remainder
35-11 = 24
24-11 = 13
13-11 = 2
The last result (2) is smaller than 11, so we stop here and this is the remainder.
Therefore, 35 = 2 (mod 11)
--------------
Here's another way to think of it. Consider you have $35 in your pocket. Let's say a store is selling trinkets for $11 each. We can pose these key questions:
What is the most number of trinkets you can buy?If you buy that max amount, how much will you have left over?The answer to the first question is 3 trinkets because 3*11 = 33 dollars is under the budget of $35. The amount left over is 35-33 = 2 dollars which is the remainder. It's not larger than 11, so we cannot buy any more trinkets at this point.

Answer:
Chunking is best for smaller numbers and arithmetic. Short division is great for dividing larger numbers by one digit numbers. Long division is handy for dividing large numbers by numbers with 2 or more digits.
Step-by-step explanation:
Seiji and Gavin both worked hard over the summer. Together they earned a total of $450. Gavin earned $50
more than Seiji.
(a) Write a system of equations for the situation. Use s for the amount Seiji earned and g for the amount
Gavin earned.
(b) Graph the equations in the system. Let the x-axis = Seiji and the y-axis = Gavin. (Complete the
numbering on the axis)
(c) Use your graph to estimate how much each person earned.
[a] If the total is 450 and Gavin (g or y) earned 50 more than Seiji (s or x) then we can create the following system:
{ s + 50 = g
{ g + s = 450
[b] See attached
[c] Gavin earned $250 and Seiji earned $200
Using the graph, we will look at where the points intercept. The x will be Seiji, and the y will be Gavin. Using this, we can see the answer is (200, 250) leaving Seiji with 200 dollars and Gavin with 250 dollars
(there is also a simpler way to do this, but as I was following the assignment I think this is what you need!)

Answer:Calculate the Land Transfer Tax on a house for 248000
Calculation example
1.multiply $55,000 by 0.5% (55,000 × 0.005) = $275.
2.multiply the amount exceeding $55,000 up to $250,000 by 1.0% (195,000 × 0.01) = $1,950.
3.multiply the amount exceeding $250,000 up to $400,000 by 1.5% (150,000 × 0.015) = $2,250.

find the values for c and d that make the function differentiable:f(x) = 5x^2 + c if x = or < than 3dx^2 - 3 if x > 3
9514 1404 393
Answer:
c = -3; d = 5
Step-by-step explanation:
The function is differentiable if it is continuous and the derivative is continuous.
This function will be continuous if the limit as x approaches 3 from either side is the same. From the left, the limit is ...
5(3^2) +c = 45 +c
From the right, the limit is ...
d(3^2) -3 = 9d -3
__
The derivative will be continuous if the limit as x approaches 3 from either side is the same. From the left, the limit is ...
f'(x) = 10x
= 10(3) = 30
From the right, the limit is ...
f'(x) = 2dx
= 2d(3) = 6d
__
This gives us a pair of simultaneous equations in 'c' and 'd':
45 +c = 9d -3
6d = 30
The latter tells us d = 5. Then the former tells us ...
45 +c = 9(5) -3 ⇒ c = -3
The function is differentiable if c = -3 and d = 5.

Additional comment
With these values, the function becomes ...

find the domain, in interval notation.
Judging by the image the function graphed has an asymptote at x = 3 and extends forever to -infinity along the x axis.
so the answer would be - infinity not included (because infinity is a concept not a number) to +3 not included because the function infinitely approaches x = 3. this is (-∞,3) in interval notation.

1 1\4-2\7 show your work
Answer:
27/28
Step-by-step explanation:
You would have to find the LCM of 4 and 7, which is 28. Then you multiply the numerators by the same number you multiplied on the denominator. You would then get 1 7/28 - 8/28 = 35/28 - 8/28 = 27/28.
Select each equation which is equivalent to 60% of 25.
0.6 • 25 = x
x • 1.6 = 25
610=x25
60100=25x
x25=60100
6.0 • 25 = x
Answer:
answer is 0.6 x 25 = x
Step-by-step explanation:
to find % of number, you simply just need to convert the percent to a decimal, which is done by division of 100.
60 / 100 = 0.6
What is the maximum value of 5 - 4x - x2 and the value of x for which the maximum occurs? Explain your answer.
Answer:
Max value: 9
Max x value: -2
Step-by-step explanation:
We're trying to find the vertex of y = 5 - 4x - x²
We can try to convert this equation to vertex form
First, subtract 5 from both sides
y = 5 - 4x - x²
- 5 -5
y - 5 = -4x - x²
Then add -4 to both sides (this is because this the sqaure of half b -4)
y - 5 - 4 = -4x - x²+ 4
y - 9 = -4 - 4x - x²
Factor the right side of the equation
y - 9 = -(x + 2)(x + 2)
y - 9 = -(x + 2)²
Add 9 to both sides
y - 9 = -(x + 2)²
+ 9 + 9
y = -(x + 2)² + 9
To find the max values we have to make it to where x + 2 = 0
x + 2 = 0
- 2 - 2
x = - 2
When we make equation inside the parenthesis 0, we get y = 9
y = -(-2 + 2)² + 9
y = -(0)2 + 9
y = 9

:
Equation at the end of step 1
(23x2 - 6x) - 3
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 8x2-6x-3
The first term is, 8x2 its coefficient is 8 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 8 • -3 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -6 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2
-3 + 8 = 5
-2 + 12 = 10
-1 + 24 = 23
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
8x2 - 6x - 3

Ellen makes and sells bookmarks. She graphs the number of bookmarks sold compared to the total money earned. What is the rate of change for the function graphed to the left?
Answer:
Given coordinates on the graph is (4,0), (8,10), (12,20).
We need to find the rate of change for the function graphed.
Actually rate of change is the second name of slope.
So, we need to find the slope between given coordinates.
We know slope formula
Let us choose first two coordinates (4,0), (8,10).
(x1,y1) = (4,0) and (x2,y2) = (8,10).
Plugging values of x1,x2,y1 and y2 in slope formula, we get
Slope=
Therefore, rate of change is 5/2 or $2.5 earned per bookmark sold.

Please help haha imm failing math 5(x−2 2/5)=−5.2
Answer:
x= 1.36
Step-by-step explanation:
Answer:
Step-by-step explanation:
5(x−2 2/5) = −5.2
1. We need to use distibutaive property
5×x and 5×-2.4
5x - 12 = -5.2
2. We need to get x alone.
5x - 12 = -5.2
-12 -12
5x = 6.8
3. We need to divide
5x = 6.8
/5 /5
x = 1. 36
check:
5(1.36−2 2/5)=−5.2
6.8 - 12 = 5.2

You can tell by what is separated by addition or subtraction.
Midpoints
H is the midpoint of iJ, and IH, = 0.75. What is the value of HJ?
IH + HJ = 2 (IH)
0.75 + HJ = 2(0.75)
0.75 + HJ = 1.5
HJ = 1.5 - 0.75

First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:

Step-by-step explanation:
200,000,000×100÷2.3= 4,600,000
2022-2013= 9
4,600,000×9= 41,400,000
200,000,000 + 41,400,000 = 241,400,000
Answer:
241,400,000
Step-by-step explanation:
200,000,000×100÷2.3= 4,600,000
2022-2013= 9
4,600,000×9= 41,400,000
200,000,000 + 41,400,000 = 241,400,000

-2x+7=3-(-2x)
Answer:
X = 1
Step-by-step explanation:
-2x + 7 = 3 - ( -2x)
-2x + 7 = 3 +2x (- - = +) (+ + = +) and (different signs always negative: - + = -)
(any term or numbers moved from one side of the = sign goes from negative to positive or from positive to negative, from multiplying to dividing and from dividing to multiplying. First isolate the additions or subtractions.)
-2x + 7 = 3 + 2x
-2x + 7 - 3 = 2x
-2x + 4 = 2x
4 = 2x + 2x
4 = 4x (a number next to a letter is multiplying. It goes to the other side of the equation dividing)
4 /4 = x
X = 1
-2x + 7 = 3 - (-2x)
-2x + 7 = 3 + 2x
-2x - 2x = 3 - 7
-4x = -4
x = 1
