Answer:
y = [tex]\frac{n}{K - m}[/tex]
Step-by-step explanation:
When doing problems like these, you should go through the process like using PEMDAS:
P - Parenthesis ()
E - Exponents [tex]x^{2}[/tex]
M - Multiply x
D - Division ÷
A - Addition +
S - Subtraction -
1) Since there aren't any Parentheses, or exponents, we should then check for any use of Multiplication.
As shown, there are no shown methods of multiplying.
BUT there is Division, so we will do the opposite of division, which is multiplication.
K = m - n ÷ y
y(K = m - n ÷ y)y
^ Trying to multiply 'y' onto both sides, because when you do something to one side, you do to the other. ^
'y' then cancels out on one side, so you will be left with:
= m - n
But on the other side you will have:
Ky
So your problem will look like:
Ky = m - n
2) Since we are trying to get 'y' by itself, instead of multiplying now, we will be dividing, because:
K(y) = Ky or you can also say K x y = Ky
Back to the problem, we will now divide 'K' to both sides, as stated before:
What you do to one side, you do to the other:
[tex]\frac{Ky}{K} = \frac{m - n}{K}[/tex]
'K' will cancel out on one side:
[tex]\frac{Ky}{K} = y[/tex]
Leaving you with:
'y'
While the other side, will be left as:
[tex]\frac{m - n}{K}[/tex]
So your final answer will be:
[tex]y=\frac{m - n}{K}[/tex]

Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan's height in centimeters? *(HINT: CHANGE HIS HEIGHT TO INCHES - HOW MANY INCHES ARE IN A FOOT? HOW MANY INCHES ARE IN 4 FEET? THEN ADD 2 INCHES) *
Answer:Joan's height is 127 centimetres
Step-by-step explanation:
Step 1
Joan is 4 feet 2 inches tall and we want to change to centimeters .
we first change her height to inches
1 Foot = 12 Inches
Therefore 4 Feet = 4 x 12 = 48 inches
Total height in inches =48 inches + 2 Inches = 50 inches
Step 2 --Now, we have gotten her height in inches, we can now change to centimetres.
We have that
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Joan's height is 127 centimetres

what are the solutions to (x+7)2 =81
Answer:
x = 33.5Step-by-step explanation:
Simplifying
(x + 7) * 2 = 81
Reorder the terms:
(7 + x) * 2 = 81
Reorder the terms for easier multiplication:
2(7 + x) = 81
(7 * 2 + x * 2) = 81
(14 + 2x) = 81
Solving
14 + 2x = 81
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + 2x = 81 + -14
Combine like terms: 14 + -14 = 0
0 + 2x = 81 + -14
2x = 81 + -14
Combine like terms: 81 + -14 = 67
2x = 67
Divide each side by '2'.
x = 33.5
Simplifying
x = 33.5

3) GRIP is a rectangle with: PS = 6x - 4
GI = 10x +4
m <1 = 2y +7 and
m3 = 6y +3.
Find:
a.) PR =
b.) m < 2 =
c.) m
Help please!
Answer:PR = 64; m∠2 = 63°; m∠RSI = 54°
because GRIP is a rectangle
=>PR = GI = 2PS
<=> 10x + 4 = 2.(6x - 4)
<=> 10x + 4 = 12x - 8
<=> 2x = 12
<=> x = 6
because PR = GI => PR = 10x + 4 = 10.6 + 4 = 64
GRIP is a rectangle => PS = SI
=> ΔPSI is a isosceles triangle
=> m∠1 = m∠2
but m∠2 + m∠3 = 90°
=> m∠1 + m∠3 = 90°
<=> 2y + 7 + 6y + 3 = 90
<=> 8y + 10 = 90
<=> 8y = 80
<=> y = 10
with y = 10 => m∠2 = 2.10 + 7 = 27
we also have: RS = SI
=> ΔRSI is a isosceles triangle
=> m∠3 = m∠4 = 90° - 27° = 63°
=> m∠RSI = 180° - 63°.2 = 54°

what kind of triangle is bcd
Answer:
C. obtuse
Step-by-step explanation:
Obstuse is a triangle with ONE angle bigger than 90 degrees.
The triangle ΔBCD will be an acute triangle. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The measure of the angle BCD is 70°. And the exterior angle of the angle BDC is 130°. The sum of the interior and exterior angles is 180°. Then the measure of the angle BDC will be
∠BDC + 130° = 180°
∠BDC = 50°
Then the measure of angle CBD will be given as,
∠CBD + ∠BDC + ∠DCB = 180°
∠CBD + 70° + 50° = 180°
∠CBD = 60°
The measure of all the angles of the triangle is less than 90°. Then the triangle ΔBCD will be an acute triangle. Then the correct option is B.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To find out how much time Patty spent on each skill, we can divide the total duration of Patty's gymnastics class by the number of skills she practices.
Given that Patty's gymnastics class is 5/6 of an hour long, we can represent the duration of the class as 5/6 hours.
Let's denote the time Patty spent on each skill as "x" hours.
Total time = 5x
The total duration of Patty's gymnastics class is 5/6 hours.
On simplifying the equation , we get
5x = 5/6
Divide by 5 on both sides , we get
5x/5 = (5/6)/5
x = 1/6
Hence , Patty spent 1/6 hours on each skill, or in other words, 1/6 of an hour on each skill

Step-by-step explanation:
information not complete, but this is the equation of a straight line, and assume you want to know the gradient
3y = 8 - 4x
3y = -4x + 8
dividing both sides by 3
y = -4/3x + 8/3
comparing the equation to equation of a straight line;

Tony worked hours on his science project. Sonia worked times as long on her science project as Tony did. For how many hours did Sonia work on her science project?
Complete question :
Tony worked 4 2/3 hours on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did. For how many hours did Sonia work on her science project?
Answer:
5 5/6 hours
Step-by-step explanation:
Given that :
Hours worked by Tony = 4 2/3
Hours worked by Sonia = 1 1/4 times as long as Tony
Hence, hours worked by Sonia = 1 1/4 * 4 2/3
5/4 * 14/3
= 70 / 12
= 5 10/12
= 5 5/6 hours

A circle has a circumference of 1{,}017.361,017.361, comma, 017, point, 36 units. What is the radius of the circle?
Answer:
[tex]r\approx 162~units[/tex]
Step-by-step explanation:
The Circumference of a Circle
The circumference is the arc length of the circle.
A circle with radius r has a circumference calculated by:
[tex]C=2\pi\cdot r[/tex]
If we are given the circumference, the radius can be calculated by solving the equation for r:
[tex]\displaystyle r=\frac{C}{2\pi}[/tex]
The circumference of the circle is 1,017.36 units. Calculating the radius:
[tex]\displaystyle r=\frac{1,017.36}{2\pi}[/tex]

A large high school offers AP Statistics and AP Calculus Among the seniors in this school 65% take AP Statistics, 45% take AP Calculus and 30% take both If a señor is randomly selected, what the probability that they are in AP Statistics or AP Calculus but not both
Answer:
0.8
Step-by-step explanation:
P(AP statistics) = 65%
P(AP Calculus) = 45%
P(AP statistics n AP Calculus) = 30%
Probability of AP statistics or AP Calculus but not both :
Probability of event A or B :
P(AUB) = p(A) + p(B) - p(AnB)
P(AP statistics U AP Calculus) = P(AP statistics) + P(AP Calculus) - P(AP statistics n AP Calculus)
= 0.65 + 0.45 - 0.30
= 0.8
= 80%
The probability of being a senior in the AP Statistics or AP Calculus but not both when selected randomly is 0.8 or 80%.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
