Answer:
YES
Step-by-step explanation:
If 18/22 is expressed in simplest terms. that is if both the numerator and denominator is divided by 2. It gives 9/11
We can determine if they are the same by multiplying both fractions by 100
9/11 x 100 = 81.8
18/22 x 100 = 81,8
they yield the same number, thus the records are the same
can somebody please solve for x and y, if you get the answers correct I'll give you extra points
Answer:
1 ,x=18,y=13.3
2,x=8,y=30
3,x=15

Jackie had a puzzle book that contains a total of 70 puzzles she has completed 2/5 of the puzzles in the book if Jackie completes 18 more puzzles what is the total number of puzzles that she will have completed in the book
Answer: 46 puzzles
Step-by-step explanation:
There are 70 puzzles in total in the book.
Jackie has completed / of those puzzles. In whole numbers that is:
= 2 /5 * 70
= 28 puzzles
She then completes 18 more puzzles.
Total that she has completed is:
= 28 + 18
= 46 puzzles
The Area of EFGH is 2x+9 which is similar to The Area of JKLM is 2x-6. The perimeter of EFGH is x+3 which is similar to the Perimeter of JKLM is x-1. FInd all Possible values of X.
Answer:
[tex]x = 9[/tex]
Step-by-step explanation:
Assume EFGH and JKLM are rectangles
JKLM appears to be the smaller of both.
So:
[tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
Where n is the scale of dilation
The area of EFGH is:
[tex]Area = EF * GH[/tex] ----- (1)
Substitute [tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
[tex]Area = n*JK * n*LM[/tex]
[tex]Area = n^2*JK * LM[/tex]
So, we have:
[tex]Area = EF * GH[/tex] and [tex]Area = n^2*JK * LM[/tex]
[tex]EF * GH = 2x + 9[/tex] --- Given
[tex]JK * LM = 2x - 6[/tex] --- Given
So:
[tex]Area = EF * GH[/tex] and [tex]Area = n^2*JK * LM[/tex]
[tex]Area = 2x + 9[/tex] and [tex]Area = n^2 * (2x - 6)[/tex]
Equate bot areas
[tex]2x + 9 = n^2*(2x - 6)[/tex]
Make n^2 the subject
[tex]n^2 = \frac{2x + 9}{2x - 6}[/tex]
The perimeter (P) of EFGH is:
[tex]P = 2*(EF + GH)[/tex] ----- (1)
Substitute [tex]EF = n * JK[/tex] and [tex]GH = n * LM[/tex]
[tex]P = 2*(n*JK + n*LM)[/tex]
[tex]P = 2n*(JK + LM)[/tex]
So, we have:
[tex]P = 2*(EF + GH)[/tex] and [tex]P = 2n*(JK + LM)[/tex]
[tex]2*(EF + GH) = x + 3[/tex] --- Given
[tex]2*(JK + LM) = x - 1[/tex] --- Given
So:
[tex]P = 2*(EF + GH)[/tex] and [tex]P = 2n*(JK + LM)[/tex]
[tex]P =x + 3[/tex] and [tex]P = n *(x - 1)[/tex]
Equate bot perimeters
[tex]x + 3 = n(x - 1)[/tex]
Make n the subject
[tex]n =\frac{x + 3}{x - 1}[/tex]
Square both sides
[tex]n^2 =\frac{(x + 3)^2}{(x - 1)^2}[/tex]
Recall that: [tex]n^2 = \frac{2x + 9}{2x - 6}[/tex]
So, we have:
[tex]\frac{(x + 3)^2}{(x - 1)^2} = \frac{2x + 9}{2x - 6}[/tex]
Evaluate all squares
[tex]\frac{x^2 + 6x +9}{x^2 - 2x + 1} = \frac{2x + 9}{2x - 6}[/tex]
Cross multiply
[tex](x^2 + 6x +9)(2x - 6) = (x^2 - 2x + 1)(2x + 9)[/tex]
Open brackets
[tex]2x^3 +12x^2 + 18x - 6x^2 -36x -54 = 2x^3 - 4x^2 + 2x + 9x^2 - 18x +9[/tex]
Subtract 2x^3 from both sides
[tex]12x^2 + 18x - 6x^2 -36x -54 = - 4x^2 + 2x + 9x^2 - 18x +9[/tex]
Collect like terms
[tex]12x^2 - 6x^2 + 18x -36x -54 = - 4x^2 + 9x^2+ 2x - 18x +9[/tex]
[tex]6x^2 - 18x -54 = 5x^2- 16x +9[/tex]
Collect like terms
[tex]6x^2 -5x^2 - 18x +16x -54 -9= 0[/tex]
[tex]x^2 -2x -63= 0[/tex]
Expand
[tex]x^2 +7x - 9x - 63 = 0[/tex]
Factorize
[tex]x(x +7) - 9(x + 7) = 0[/tex]
[tex](x -9) (x + 7) = 0[/tex]
[tex]x = 9\ or\ -7[/tex]
x can not be negative.
So: [tex]x = 9[/tex]
If y lies on a number line , and x is added to y , which of the following would be true about the location of y + x?
Answer:
Step-by-step explanation:
If x is a positive number then y + x lies to the right of y, if x is a negative number then the location of y + x will be to the left, if x is zero then y and y + x are the same point

Which inequality represents "six times a number is less than negative thirty-nine and three-quarters"? 6x > –39Three-fourths 6 + x > -39 Three-fourths 6x < -39Three-fourths 6 x less-than-or-equal-to negative 39 and three-fourths
Given:
The phrase is "six times a number is less than negative thirty-nine and three-quarters".
To find:
The inequality represented by the given phrase.
Solution:
Let x be the unknown number.
Six times a number is "6x".
Less than is "<".
Negative thirty-nine and three-quarters is "[tex]-39\dfrac{3}{4}[/tex]".
So, six times a number is less than negative thirty-nine and three-quarters is:
[tex]6x<-39\dfrac{3}{4}[/tex]
Therefore, the correct option is C.
Answer:
"six times a number is less than negative thirty-nine and three-quarters".

It's the fourth answer, y=10. This is because the line is a straigh line is 180 degrees, which is shown in the photo. You have to take away 120 degrees (the angle is the same on both sides) which would leave you with 60. Then, thats the sum of the angle, but since were solving for y, you have to divide 60 by 6, which gives you your answer, 10. Hope this helps, if you need anything else you can message me!

Answer:
it's 5/12 + 1/3
Step-by-step explanation:
you would multiply the -5/6 by -1/2 to get 5/12 since the negative would cancel out
so 5/12 + 1/3 would be the answer.
Also this question doesn't make any sense since you are supposed to simplify the parentheses first.
Consider best strategy to solve the problem. If 9 inches are equal to 27 feet on a map how many feet are equal to three inches
Answer:
9
Step-by-step explanation:
If 9 inches equal 27 what you would do is divide in order to find how much feet would be in 1 inch. So:
9/27= 3 feet
Then to find how much feet are equal to 3 inches you just multiply that by 3. So your answer is 9 feet.
Overall the work should look like
9 inches= 27 feet
9/9 inches= 27/9 feet
1 inch = 3 feet
3 inches x 3 feet
= 9

What is the area of the shaded region?
Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²
Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²

Step-by-step explanation:
Part A
x-intercepts of the graph represent the value of goods at which profit of of the company is zero → Break even of the company
Maximum value of the graph represents the maximum profit of the company at certain price of the goods.
Part B
Interval in which the function is increasing → x = 0 to x = $3
Profit of the company increases when price of the goods increase from 0 to 3.
Interval in which the function is decreasing → x = $3 to x = $6
Profit of the company decreases when the price of the goods increases from 3 to 6.
Part C
Average rate of change of the function from x = a and x = b,
= [tex]\frac{f(b)-f(a)}{b-a}[/tex]
By applying the same rule,
Average rate of change of the function between x = 1 and x = 3
= [tex]\frac{120-60}{3-1}[/tex]
= [tex]\frac{60}{2}[/tex]
= 30
