What is the value of y?
y + 35 = ( y ) + ( y - 31 )
y + 35 = 2y - 31
Add both sides 31
y + 35 + 31 = 2y - 31 + 31
y + 66 = 2y
Subtract both sides y
y - y + 66 = 2y - y
y = 66

Solve the equation:
3x - 5 = -26
Answer:
x = -7
Explanation:
Move the constant to the right-hand side and change its sign:
3x = -26 + 5
Calculate the sum:
3x = -21
Divide both side of the equations by 3:
Therefore, the answer will be x = -7
Answer:
[tex]3x - 5 = - 26 \\ \\ = > 3x = - 26 + 5 \\ \\ = > 3x = - 21 \\ \\ = > x = - \cancel\frac{ - 21}{3} \\ \\ = > x = - 7[/tex]

In order to do perimeter you need to add each corners value, in this case a to B is one side and A to D is another, in order to get from A to B you have to walk 3 units, so their is our first part, now for the second you need to walk from point a to point D which if you do it will be 4 units.
Now we have 2 numbers, 4 and 3, We still have the other side but it will be the same, so you will do 4+4 and 3+3, in this case it will be 8+6 so the answer should be 14. I might be wrong.
In an all boys school, the heights of the student body are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. What is the probability that a randomly selected student will be shorter than 63 inches tall, to the nearest thousandth?
The probability that a randomly selected student from the all-boys school will be shorter than 63 inches tall is approximately 0.9%.
To find the probability that a randomly selected student will be shorter than 63 inches tall, we need to use the standard normal distribution table or a statistical calculator.
Calculate the z-score for the value of 63 inches using the formula:
z = (X - μ) / σ
where X is the value (63 inches), μ is the mean (70 inches), and σ is the standard deviation (3 inches).
z = (63 - 70) / 3
z = -7 / 3
z = -2.3333
Now, we look up the area to the left of the z-score -2.3333 in the standard normal distribution table.
Using a standard normal distribution table, the cumulative probability for z = -2.33 (rounded to two decimal places) is approximately 0.009.
So, the probability that a randomly selected student will be shorter than 63 inches tall is approximately 0.009 or 0.9% (rounded to the nearest thousandth).

£730 is divided between June, Sushil & Fiona so that June gets twice as much as Sushil, and Sushil gets three times as much as Fiona. How much does Sushil get?
Answer:
Sushil gets $219.
Step-by-step explanation:
With the information provided, you can write the following equations:
It says that £730 is divided between June, Sushil & Fiona, which can be expressed as:
x+y+z=730 (1), where:
x is the amount June gets
y is the amount Sushil gets
z is the amount Fiona gets
Also, the statement indicates that June gets twice as much as Sushil which means that the amount June gets is equal to two for the amount Sushil gets:
x=2y (2)
Besides, you know that Sushil gets three times as much as Fiona which means that the amount Sushil gets is equal to 3 for the amount Fiona gets:
y=3z (3)
Now, you can replace (3) in (1) and (2) and you will have 2 new equations:
x=2(3z)
x=6z (4)
x+3z+z=730
x+4z=730 (5)
You have the following equations:
x=6z (4)
x+4z=730(5)
Next, you can replace (4) in (5) and solve for z:
6z+4z=730
10z=730
z=730/10
z=73
Now, you can replace the value of z in (3):
y=3z
y=3(73)
y=219
Finally, you can replace the value of y in (2):
x=2y
x=2(219)
x=438
According to this, the answer is that Sushil gets $219.

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2), (-2,1).Find the value of k
Answer:
[tex]k = 1[/tex]
Step-by-step explanation:
Given
[tex]3y = 5x + k[/tex]
Opposite points: [tex](1,-2)[/tex] and [tex](-2,1)[/tex]
Required
Find k
First, calculate the midpoint of the opposite points.
[tex](x,y) = 0.5(x_1 + x_2,y_1 + y_2)[/tex]
This gives:
[tex](x,y) = 0.5(1 -2,-2 + 1)[/tex]
[tex](x,y) = 0.5(-1,-1)[/tex]
Open bracket
[tex](x,y) = (-0.5,-0.5)[/tex]
The equation [tex]3y = 5x + k[/tex] becomes:
[tex]3 * -0.5 = 5 * -0.5 + k[/tex]
[tex]-1.5 = -2.5 + k[/tex]
Solve for k
[tex]k = 2.5-1.5[/tex]
[tex]k = 1[/tex]

What are the first three terms of the sequence defined by the recursive function an = an-1-(an-2-4), when a5 =-2 and a6 = 0?
-14, 14,- 4
6, 10,8
-2 0,2
2, 8, 10
Answer:
6, 10 and 8
Step-by-step explanation:
Given the recursive function an = an-1-(an-2 - 4), when a5 =-2 and a6 = 0?
a6 = a5 - (a4 - 4)
0 = -2 - (14 - 4)
2 = - (a4 - 4)
-2 = a4 - 4
a4 = -2 + 4
a4 = 2
a5 = a4 - (a3 - 4)
-2 = 2 - (a3 - 4)
-2-2 = - (a3 - 4)
-4 = -(a3 - 4)
4 = a3 - 4
a3 = 4+4
a3 = 8
Also
a4 = a3 - (a2 - 4)
2 = 8 - (a2 - 4)
2-8 = - (a2 - 4)
-6 = -(a2 - 4)
6 = a2 - 4
a2 = 6+4
a2 = 10
a3 = a2 - (a1 - 4)
8 = 10 - (a1 - 4)
8-10 = - (a1 - 4)
-2 = -(a1 - 4)
2 = a1 - 4
a1 = 2+4
a1 = 6
Hence the first 3 terms are 6, 10 and 8

C. 6, 10, 8

13 card of each category is present
So, there are 13 spades present in the deck
Probability is the ratio of favorable to the total outcomes.
[tex]\therefore P=\dfrac{13}{52}\\\\\Rightarrow P=\dfrac{1}{4}[/tex]
AADE and AABC are similar. Which best explains why the slope of the line between
points A and D is the same as the slope between points A and B?
The triangles are similar, so the sides are proportional:
AE = AC and DE = BC. Therefore, De = BC, so the slope of
AD is the same as the slope of AB.
Points A, D and B are on the hypotenuses of similar triangles.
Therefore, AD = AB, so the slope of AD is the same as the
slope of AB
The triangles are similar, so the sides are proportional:
DE = BC. Therefore, the slope of AD is the same as the slope
of AB
AE C
The triangles are similar, so the sides have equal lengths.
Therefore, AD = DB, so the slope of AD is the same as the
slope of AB
Answer:
(c) The triangles are similar, so the sides are proportional: DE = BC. Therefore, the slope of AD is the same as the slope of AB
Step-by-step explanation:
Given
See attachment for proper format of question
Required
Why is the slope between A and D the same
From the question, we understand that:
[tex]\triangle ADE[/tex] and [tex]\triangle ABC[/tex] are similar
This implies that similar sides are proportional.
i.e.
[tex]AD \to AB[/tex]
[tex]AE \to AC[/tex]
[tex]DE \to BC[/tex]
Slope (m) is calculated as:
[tex]m = \frac{Rise}{Run}[/tex]
So, the slope of [tex]\triangle ADE[/tex] is:
[tex]m = \frac{DE}{AE}[/tex]
Slope of [tex]\triangle ABC[/tex] is:
[tex]m = \frac{BC}{AC}[/tex]
Since the triangles are similar, then:
[tex]m = m[/tex]
i.e.
[tex]\frac{DE}{AE} = \frac{BC}{AC}[/tex]
Hence, (c) is true
