Simplify, the fraction 25/35
Answers
Answer:
5/7
Step-by-step explanation:
Hi, so the question is simplify 25/35. each fraction can be divided by five.
So each will be divided by five. So, first the numerator which is the top of the fraction. 25/5=5 so the new simplified top is 5.
The denominator, the bottom fraction, 35/5= 7, so the new simplified denominator is 7.
Refix the fraction and you have that 25/35 = 5/7
Answer:
5/7
Step-by-step explanation:
Say you got a 25 out of 35 questions right on a test you got 5/7 of them correct and get a 71.43% right.
Or think of it like 7 can go into 35 a total of 5 times and 5 can also go into 25 5 times.
Hope this helps have a great day:)

Answer:
(9,3)
Step-by-step explanation:
Use elimination to solve.
-2 (-3x + 3y = -18)
6x - 6y = 36
-6x - 3y = -63
The 6x and -6x are eliminated and you are left with -9y = -27 when you combine -6y and -3y, and 36 - 63.
y = 3
Then, substitute 3 into either equation to find x
-3x + 3(3) = -18
-3x + 9 = -18
-3x = -27
x = 9
There are 6 lines. The 1st line has 9 people, 2nd line 11 people, 3rd 13 people.

Step-by-step explanation:
Hello!
Step 1:
First, we want to calculate what percentage of the random sample voted pretzels. To do that, we divide the number of pretzel voters depending on the total number of voters.
Calculate:
Pretzel voters ÷ Total voters27 ÷ (78 + 27 + 55 + 65)27 ÷ 2250.1212%So, approximately 12% of the sample voted on pretzels.
Step 2:
Now that we know the average percentage of people that want pretzels, we can find the same percentage of the actual population of 2600 people.
We need to solve for 12% of 2600
Calculate:
12% of 26000.12 * 2600312Based on our percentages, we predict that 312 people favor pretzels.

WHat is the best method for this system?
Answers
Answer:
Elimination method
Step-by-step explanation:
We have a choice to eliminate the y or x:
I chose x
So now we double the second equation to make the co efficient of x the same:
6x-5y = -3
6x+4y = 24
Now we subtract both equations to eliminate the x's:
6x-5y = -3
- - -
6x+4y = 24
-9y = -27
y = 3
Now we substitute this value into either equation 1 or 2:
I chose 2
3x + 2(3) =12
Simplify:
3x + 6 =12
Subtract 6 from both sides:
3x + 6 -6 = 12 -6
Simplify:
3x = 6
Divide both sides by 3:
3x÷3 = 6÷3
Simplify:
x = 2
Answer:
(2, 3 ) by the elimination method
Step-by-step explanation:
6x - 5y = - 3 → (1)
3x + 2y = 12 → (2)
multiplying (2) by - 2 and adding to (1) will eliminate x
- 6x - 4y = - 24 → (3)
add (1) and (3) term by term to eliminate x
0 - 9y = - 27
- 9y = - 27 ( divide both sides by - 9 )
y = 3
substitute y = 3 into either of the 2 equations and solve for x
substituting into (2)
3x + 2(3) = 12
3x + 6 = 12 ( subtract 6 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
solution is (2, 3 )
30 POINTS HURRY! Which of these graphs represents x < -1?
Answers
Answer:
Option A
Step-by-step explanation:
Given the following question:
[tex]x < -1[/tex]
Keep a few things in mind when graphing the inequality:
. x value is less than -1 (which means the line will go in the direction of the x)
. < is a greater sign not greater than or equal (≤) so it would be a open dot.
. The number line starts at -1.
According to all this information your answer is indeed option A.

A machine part is a 4-in. -square piece of metal plate with a round hole 2 in.
in diameter drilled through the center. What is the equation of the circle given
that the piece of metal is placed in Quadrant 1 with its corner at the origin?
Answers
The round hole in the square machine part is an inscribed circle
The equation of the circle is [tex](x - 2)^2 + (y - 2)^2 = 1[/tex]
How to determine the equation of the circleThe corner of the square machine part is said to be at the origin.
This means that, the coordinates of the machine parts are:
(x,y) = (0,0), (4,0), (4,4) and (0,4)
Calculate the midpoint of the diagonals, to determine the midpoint of the circle.
(x,y) = 0.5 * (0 + 4, 4 + 0)
This gives
(x,y) = (2,2)
The diameter of the circle is:
d = 2 inches
Divide by 2 to calculate the radius
r = 1 inch
The equation of a circle is represented as:
[tex](x - a)^2 + (y - b)^2 = r^2[/tex]
Where:
Center = (x,y) = (a,b) = (2,2)
So, we have:
[tex](x - 2)^2 + (y - 2)^2 = 1^2[/tex]
Evaluate the square of 1
[tex](x - 2)^2 + (y - 2)^2 = 1[/tex]
Hence, the equation of the circle is [tex](x - 2)^2 + (y - 2)^2 = 1[/tex]

The answer is (B), because the rate of the function is 0.50 from 0 to 8 ounces, thus the line should have a slope of 1/2. But afterward, it levels off horizontally as every ounce above 8 ounces to 12 ounces is $4.
Hope that helps!
Answer:
B
Step-by-step explanation:
Since it is 0.5 per serving between 0 and 8 ounces the graph would intersect at (1, 0.5) and it does for B. And then it says $4 for any serving 8 oz and 12 oz. B shows that the line changes to 4 dollars when it reaches 8 oz. Sorry for the terrible explanation.
