Answer:
v=16/3
Step-by-step explanation:
3(2v-9)=5
Multiply 2v and -9 with 3
6v-27=5
Add 27 to both sides
6v=32
Divide both sides by 6
v=16/3
The price of a share of stock for Nike at the beginning of the week was $24.75. Over the next five days, the share of stock gained $2.50 on Monday, lost $3.25 on Tuesday, lost $0.75 on Wednesday, gained $1.25 on Thursday, and gained $4.75 on Friday. What was the price of the share of stock at the end of Friday? A. $37.25 B. $29.25 C. $12.25 D. $22.50 What is the Answer?
Answer: B. $29.25
Step-by-step explanation:
In integers loss is represented by negative integers whereas profit is represented by positive numbers.Given, Beginning price = $24.75
Over the next 5 days,
On Monday, gain of $2.50 represented by + $2.50.
On Tuesday, loss of $3.25 represented by - $3.25 .
On Wednesday, loss of $0.75 represented by - $0.75.
On Thursday, gain of $1.25 represented by + $1.25.
On Friday, gain of $4.75 represented by + $4.75.
Price of the share of stock at the end of Friday = (Beginning price)+ ( + $2.50 - $3.25- $0.75+ $1.25+ $4.75)
= $( 24.75 + 2.50 -3.25 -0.75 +1.25 +4.75)
= $29.25
Hence, the correct option is B. $29.25.

For how many games is the total cost of bowling equal for the two bowling establishments? Family bowling game $4, shoes $1. Knight owl bowling game $3.75, shoes $2.
Answer: If you play 4 games, the price will be the same in the two establishments.
Step-by-step explanation:
Ok, in Family Bowling we have:
$4 per game, plus $1 per shoes (the shoes are paid only one time).
Then, the price for X games, is:
Pa(X) = $4*X + $1.
In Knight Owl Bowling we have:
$3.75 per game and $2 for the shoes, the price for X games will be:
Pb(X) = $3.75*X + $2.
Now, if we want to pay the same in both establishments, we have:
Pa(X) = Pb(x)
$4*X + $1 = $3.75*X + $2
Now we should solve this for X.
$4*X - $3.75*X = $2 - $1 = $1
($4 - $3.75)*X = $1
$0.25*X = $1
X = $1/$0.25 = 4.
If you play 4 games, the price will be the same in the two establishments.
If Mary and Tom put their money together they have £36. If Mary's money were halved and Tom's money doubled they would have £42. How much does each of them have? If you're answering, could you please show working out, thanks so much.
Answer:
Mary has £20 and Tom has £16
Step-by-step explanation:
Represent their current respective money amounts by m and t.
Then m + t = £36, but also m/2 + 2t = £42.
Multiplying the second equation by 2 removes the fraction:
m + 4t = £84
and multiplying this by -1 results in
-m - 4t = -£84, which can now be added to the first equation m + t = £36:
-m - 4t = -£84
+m + t = £36
---------------------
-3t = -£48
We have successfully eliminated m. To solve this last result for t, divide both sides by -3, obtaining t = £16
Since m + t = £36 and t = £16, m must be £20.
Mary has £20 and Tom has £16

Drag the numbers to order them from least to greatest.
Answer:
[tex]\sqrt{7}[/tex], 2.8, [tex]\pi[/tex], [tex]\sqrt{17}[/tex], 4.6
Step-by-step explanation:
To order the numbers from least to greatest turn all the numbers into decimal form.
[tex]\sqrt{7}[/tex]: 2.65
[tex]\sqrt{17}[/tex]: 4.12
[tex]\pi[/tex]: 3.14
4.6
2.8
Now order them from least to greatest (make sure you put the numbers back into their original form)
[tex]\sqrt{7}[/tex], 2.8, [tex]\pi[/tex], [tex]\sqrt{17}[/tex], 4.6
The numbers in the form of least to greatest will be [tex]\sqrt{7}[/tex], [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], 4.6.
What are rational and irrational numbers ?Rational numbers are those numbers which have terminating,Repeating or recurring digits after the decimal place.
Irrational numbers have non-repeating, non-recurring non-terminating digits after the decimal place.
According to the given question we have to order the number from least to greatest.
Given number are 4.6, [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], [tex]\sqrt{7}[/tex].
We know the value of π is 3.14 approx and square root of 17 lies between square root of 16 and 25 which are 4 and 5 but more close to 4 and square root of 7 lies between square root of 4 and 9 which are 2 and 3.
∴ The given numbers in increasing order will be
[tex]\sqrt{7}[/tex], [tex]2\overline{.8}[/tex], π, [tex]\sqrt{17}[/tex], 4.6.

7 times the difference of a number and 1
answer: 7(x-1)
hope this helps you
Answer: The answer is 7(x - 1).
Step-by-step explanation:
So far, we know that the givens are:
7 times the difference of a number and 1
We just need to understand what it says:
7 times ( difference of a number and 1)
So "the number" can be any number, but you have to replace it with a variable such as n, s, x, etc. And by the way, difference is from subtraction, the result of the subtraction of 1 from the unknown number. Using this, we get:
7(x - 1)

Factor of 3x-3a+xy-ay
Answer:
(3 - y) & (x - a) are the factors
Step-by-step explanation:
3x-3a+xy-ay
=> 3x - xy - 3a - ay
=> x(3 - y) - a(3 - y)
=> (3 - y)(x - a)
(3 + y) & (x - a) are the factors of the expression 3x-3a+xy-ay.
Here, we have,
given that,
the expression is : 3x-3a+xy-ay.
now, we have,
To factor the expression 3x - 3a + xy - ay, we can group the terms as follows:
3x-3a+xy-ay
=> (3x - 3a) + (xy - ay)
Now, let's factor out the common factors from each group:
=> 3(x - a) + y(x - a)
Notice that both terms now have a common factor of (x - a).
We can factor out this common factor:
=> (x - a)(3 + y)
Therefore, the factored form of the expression 3x - 3a + xy - ay is (x - a)(3 + y).
Hence, (3 + y) & (x - a) are the factors of the expression 3x-3a+xy-ay.

inverse of g(x)=2x -8
Answer:
The inverse is 1/2x +4
Step-by-step explanation:
g(x)=2x -8
y = 2x-8
Exchange x and y
x = 2y-8
Solve for y
x+8 = 2y-8+8
x+8 = 2y
Divide by 2
1/2 x + 8/2 = 2y/2
1/2x +4 = y
The inverse is 1/2x +4
Answer:
y = 1/2x + 4
Step-by-step explanation:
The first equation is y = 2x - 8
switch out y for x
x = 2y - 8
add 8 to both sides
2y = x + 8
divide by 2 on each side
y = 1/2x + 4

3х – 13 = 23
Please give an explanation to the answer
Answer:
x = 12
Step-by-step explanation:
3x - 13 = 23
Bring non-variable numbers to other side:
3x = 36
Divide both sides by 3:
x = 12
Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.
