Answer:
5/9
Step-by-step explanation:
Let the denominator be x and numerator be y.
Given, numerator is 4 less than denominator
=> y = x - 4 ...(1)
When 5 is added to both:
Numerator = y + 5 , and, denominator = x + 5
Now their ratio is 5/7.
=> (y + 5)/(x + 5) = 5/7
=> 7(y + 5) = 5(x + 5)
=> 7y + 35 = 5x + 25
=> 7y - 5x = 25 - 35
=> 7(x - 4) - 5x = -10 {y=x-4}
=> 7x - 28 - 5x = -10
=> 2x = 18
=> x = 9
Thus,
Fraction is y/x = (x-4)/x = (9-4)/9 = 5/9

Answer:
option A. 5 apples for $2.50
Step-by-step explanation:
You must find the price per apple for each option by dividing the cost in cents by the number of apples. 250 cents divided by 5 apples gives you 50 cents per apple, while option c is 55 cents per apple, option b is 60 cents per apple, and option d is 52 cents per apple.

Answer:
a = 14
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, sum to 180°
a² - 10a + 7a + 26 = 180
a² - 3a + 26 = 180 ( subtract 180 from both sides )
a² - 3a - 154 = 0 ← in standard form
(a - 14)(a + 11) = 0 ← in factored form
Equate each factor to zero and solve for a
a - 14 = 0 ⇒ a = 14
a + 11 = 0 ⇒ a = - 11
Since a > 0 , then a = 14
Equation practice with vertical angles solve for x
Answer:
x = -11
Step-by-step explanation:
6x+185 = 8x+207
substract 8 from both side and you will get
-2x = 22
and then divide by -2 and x will be equal to
x = -11

Answer:
3.14 units
Step-by-step explanation:
The formula for the length of an arc is ...
s = rθ
where r is the radius of the circle, and θ is the central angle in radians.
__
The relationship between degrees and radians is ...
180° = π radians
If we divide this equation by 3, we see ...
60° = π/3 radians
__
The radius is given as 3 units, so the arc length is ...
s = (3 units)(π/3) = π units
The arc length is 3.14 units.

Answer:
The second option: 1/4 x (26 - 10) x 3
Step-by-step explanation:
"The difference of 26 and 10" indicates that those two numbers are going to be subtracted, which is why you get (26 - 10).
The "of" in "1/4 of" means that the value after the "of" is getting multiplied by the 1/4: 1/4 x (26 - 10)
The "3 times" means that the 3 is getting multiplied by whatever comes after it, which is why the answer is the second option: 1/4 x (26 - 10) x 3

Which point of concurrency is NOT always inside a triangle? Check all that apply. A. circumcenter B. incenter C. orthocenter D. centroid
The point of concurrency which is not always inside a triangle is circumcenter and orthocenter.
We are given that;
The four options
Now,
A point of concurrency is a single point shared by three or more lines1. In a triangle, there are four points of concurrency that are associated with different types of line segments: centroid, incenter, circumcenter and orthocenter.
The centroid is the point of concurrency of the medians of a triangle, which are the line segments that connect the midpoints of the sides to the opposite vertices. The centroid is always inside the triangle.
The incenter is the point of concurrency of the angle bisectors of the triangle, which are the line segments that divide the angles into two equal parts. The incenter is also always inside the triangle.
The circumcenter is the point of concurrency of the perpendicular bisectors of the sides of the triangle, which are the line segments that are perpendicular to the sides and pass through their midpoints.
The circumcenter can be inside or outside the triangle, depending on the type of triangle. For an acute triangle, it is inside; for a right triangle, it is at the midpoint of the hypotenuse; for an obtuse triangle, it is outside
Therefore, by triangle the answer will be circumcenter and orthocenter.

Find the area of each circle. Use 3.14 for the value of pi. Round your answer to the nearest tenth. Do NOT include units in your answer (ie. ft, in, km, etc.) (FR)
Answer:
12.6
Step-by-step explanation:
The equation for a circle's area is [tex]A=\pi r^2[/tex].
We can use this equation to end up with A=(3.14)4
And 3.14 times 4 is 12.56.
Then we have to round to the nearest tenth.
Therefore your answer is 12.6

Find the distance between (-1,-2) and (8,9)
Answer:
[tex]\sqrt{202}[/tex] units or 14.2 units (rounded to the nearest tenth)
Step-by-step explanation:
To find the distance between a pair of two points, use the distance formula [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:
[tex]d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}[/tex]
So, as an exact answer, the distance is [tex]\sqrt{202}[/tex] units.
(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)
Answer:
14.2
Step-by-step explanation:
All you need to do is plug the coordinates into the distance formula.
√(x2 - x1)² + (y2 - y1)²
√[8 - (-1)]² + [9 - (-2)]²
√(9)² + (11)²
√81 + 121
√202

-4/5y - 4/5x
Step-by-step explanation:
The fraction ( -4/5 ) will multiply each component in the bracket. That is the (y) and the (x)
So -4/5 × y gives you -4/5y
and -4/5 × x gives you -4/5x
Therefore you have -4/5y - 4/5x
