Find x when f(x)=1 . (These means find the input that gives an output of 1.)
f(x)=1/x-2
Answer:
x = 1/3
Step-by-step explanation:
1 = 1/x -2
add 2 to both sides

Paul has $3.69. His sister gives him
another $5.25, and he goes out and
buys a CD single for $3.99. How
much does he have left?
Answer:
$4.95
Step-by-step explanation:
Paul originally has $3.69.
His sister gives him $5.25.
$3.69 + $5.25 = $8.94
The CD single cost him $3.99
$8.94 - $3.99 = $4.95
Therefore, he has four dollars and 95 cents ($4.95) left.
Answer:
$4.95
Step-by-step explanation:
3.69+5.25= 8.94
8.94-3.99=4.95
Solve for x Enter your answer, as one inequality,in the box
Answer:
x= (1,8)
Step-by-step explanation:
Answer:
Step-by-step explanation:
-3≤ 6x - 9 Add 9 to both sides
-3 + 9 ≤ 6x Combine left
6 ≤ 6x Divide by 6
6/6 ≤ 6x/6
1 ≤ x
6x - 9 < 39 Add 9 to both sides
6x < 39 + 9 Combine
6x < 48 Divide by 6
6x/6 < 48/6
x < 8
So the inequality is
1 ≤ x < 8
I think that is what you want. You have to express it as a combined inequality.

write 8xmxn without the multiplication sign
Step-by-step explanation:
[tex]8mn[/tex]
or equivalently
[tex]8\cdot m\cdot n[/tex]
We often write variable side-byside without the multiplication sign in algebra. It also applies to terms with indices. For instance,
[tex]\text{We write }a^2b^3c^4\text{ and mean }a^2\times b^3\times c^4[/tex]
We may, often also add a dot at the middle of both terms as another version of multiplication sign for better readability if the terms are more complicated, for instance
[tex]a\cdot b\cdot c[/tex]
and
[tex]\frac ab\cdot \sqrt{\frac{d^4}{b^9}}\cdot\pi[/tex]

What would be the equation to you have a part time job. You work for 3h on Friday and 6h on Saturday. You also recieve an allowance of 20 per week. You earn 92 per week how much do you earn per hour at your part time job
What is the equation for this promblem?
Answer:
Step-by-step explanation:
So, to go about your question, we must first ask, how many hours a week is being worked?
In this problem, that is 9 hours per week.
Next, we must question how much per week is made
That is $92 per week
Finally, we must determine if the allowance is occuring many times in the week or just once.
In this problem, that is only occuring once for the week.
So, the equation we must setup is 9x +20 =92.
To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.
9x+20=92
-20 -20
Now our equation is
9x=72
Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.
9x=72
9 9
x=8 because of 72/9 is equal to 8.
I hope this helps, and I will answer any questions you have.

One garden had 5 times as many raspberry bushes as a second garden. After 22 bushes are transplanted from the first garden to the second garden, the number of raspberry bushes in the gardens are the same. How many bushes did each garden have originally?
Please show work and no links or files! :)
To solve this problem form the system of equations as per statements given in the question then get the answer by solving them.
Number of bushes in garden one were 55 and in second garden 11 originally.
Let the number of raspberry bushes in one garden = x
And the number of raspberry bushes in second garden = y
Garden one has 5 times as many raspberry bushes as second garden,So the equation for the given statement will be,
x = 5y -------(1)
22 bushes were transplanted from garden one to the second, number of bushes in both the garden becomes same,Therefore, equation for this statement will be,
(x - 22) = (y + 22)
x - y = 22 + 22
x - y = 44 ------(2)
Substitute the value of x from equation (1) to equation (2)
5y - y = 44
4y = 44
y = 11
Substitute the value of 'y' in equation (1),
x = 5(11)
x = 55
Therefore, Number of bushes in garden one were 55 and in second garden 11 originally.

find a formula for the sun S of any three consecutive odd number?
Answer:
Let first no. be x
Therefore,
2nd no. is x+1
Third no. is x+2
SUM OF NO.'s=x+x+1+x+2

A bag contains 8 black marbles, 5 white marbles and 12 red marbles. What is the probability of selecting a red marble, not replacing it, then selecting a white marble?
Answer:
1/10
Step-by-step explanation:
8 black marbles, 5 white marbles and 12 red marbles = 25 marbles
P(red) = red/total = 12/25
Remove the marble
8 black marbles, 5 white marbles and 11 red marbles = 24 marbles
P(white) = white/total = 5/24
P(red, remove,white) = 12/25 * 5/24
=12/24 * 5/25
=1/2 * 1/5
=1/10
Step-by-step explanation:
Total balls = 12 + 5 + 8 = 25 marbles
Probability of getting white marbles = 5/24
Probability of red marbles = 12/24 = 1/2
Now
Probability = 1/2 × 5/24 + 1
Probability = 1/2 × 5/25
Probability = 5/50
Probability = ⅒
