Answer:
x = m × p - n
Step-by-step explanation:
[tex]m = n + \frac{x}{p} [/tex]
We can first multiply both sides by p.
[tex]m \times p = n + x[/tex]
And now we only have n left with x, so we subtract n on both sides.
[tex]m \times p - n = x \\or \\ x = m \times p - n[/tex]

Only 30 of Jahanna's 40 customers receive the newspaper on Sunday's. If it takes her 50 minutes to deliver to 40 customers on other days, how long will it take her to deliver the paper to 30 customers?
Answer: 37.5 minutes
Step-by-step explanation:
It takes Jahanna 50 minutes to deliver to 40 customers.
On Sunday however, she has to deliver to only 30 customers.
Assume that the amount of time it will take her is x minutes and use direct proportion:
50 minutes : 40 customers
x minutes : 30 customers
Cross multiply:
40x = 50 * 30
40x = 1,500
x = 1,500/40
x = 37.5 minutes

Find the values of x and y
Can someone help?
Answer:
[tex](x,y) = (65^\circ, 50^\circ)[/tex]
Step-by-step explanation:
Let all values denote degrees.
By the exterior angle theorem, [tex]x + y = 115[/tex]. Moreover, because we are dealing with an isoceles triangle, [tex]y = 180 - 2x[/tex]. Substituting this into the former equation gives [tex]180-x=115[/tex] and as such [tex]x=65[/tex]. Because [tex]x + y = 115[/tex] we now also know that [tex]y=50[/tex].
Answer:
x° = 65° & y° = 50°.
Step-by-step explanation:
115° = x° + y° ( exterior angle property )
Let's name that angle to the right of 115° as 'a'.
a = 180 - 115 = 65°. (linear pair)
Now we know that the triangle is an isosceles triangle. (given)
So this makes x° also as 65° (equal sides make equal angles).
This leaves behind y°.
y° = 180 - (65+65) = 50°.
So, x° = 65° & y° = 50°.

The Taylors have a square rug in their living room that is "x" feet long on each side. The room is 3
feet wider and 5 feet longer than the rug. Write an expression to describe the perimeter of
the living room.
Answer:
[tex]Perimeter = 4x+16[/tex]
Step-by-step explanation:
Given
[tex]Rug=x[/tex]
Required
Determine the perimeter of the room
The room is 3ft wider.
So:
[tex]Width = Rug + 3[/tex]
[tex]Width = x + 3[/tex]
The room is 5ft longer,
So:
[tex]Length = Rug + 5[/tex]
[tex]Length = x + 5[/tex]
The perimeter is:
[tex]Perimeter = 2 * (Length + Width)[/tex]
[tex]Perimeter = 2 * (x+5+x+3)[/tex]
Collect Like Terms
[tex]Perimeter = 2 * (x+x+5+3)[/tex]
[tex]Perimeter = 2 * (2x+8)[/tex]
[tex]Perimeter = 4x+16[/tex]

Point B is the midpoint of AC, and point C is the midpoint of AD. If CD=12, what is AB?
Answer: AB = 6
Step-by-step explanation:
If CD = 12 , AC also = 12
B is the midpoint of AC so one side = 6
AB is one side of AC , so AB = 6
I am not a professional, I am simply using prior knowledge!
Note- It would mean the world to me if you would mark me brainliest!
The Distance between AB will be 12 units
ConceptFirst we will find the distance between point A and CAfter that we will divide the distance between A and C by 2 to find ABWhat are steps to solve this problem?The steps are as follow:
Distance between CD is given which is 12 unit To find AC we will double the distance between CD because C is midpoint of ADSo distance AC is given by:AC = 2 x CD = 2 x 12 = 24 units
To find AB we will divide the AC by 2 because B is midpoint of ACSo distance AB is given by:AB = AC/2
AB = 24/2 = 12 units
So Distance between points AB will be 12 units

Explain in complete sentences how you convert a log function to an exponential.
Answer:
Identifying and moving the base is the key to changing from logarithmic form into exponential form. Identifying the base of the logarithmic equation and moving the base to the other side of the equal sign is how to change a logarithmic equation into and exponential equation.
Example- log 8 base 2=3
then 2^3=8
The opposite of a logarithmic function is an exponential equation, and vice versa
As a general rule, we have the following equation to convert a log function to an exponential.
[tex]\log_ba = x \to a = b^x[/tex]
Take for instance, we have the following logarithmic function

Which is better to buy, 6 CD's for $12 or 8 CD's for $14.50?
Answer:
8 CDs for $14.50
Step-by-step explanation:
We have to divide both of the numbers by the number of CDs. Our formula is:
(price) ÷ (number of CDs) = price per CD
When we divide both of the prices by the number of CDs, we see that 6 CDs for 12.00 is worse because it is 2.00, whereas the inflation is lower when you compare to the other rate. You get $1.81.

Answer:
Total copies sold= 486,585
Step-by-step explanation:
Giving the following information:
Number of copies sold in the first month= 39,900
% of copies sold in the first month= 8.2%
To calculate the total number of copies sold, we need to use the following formula:
Total copies sold= Number of copies sold in the first month/% of copies sold in the first month
Total copies sold= 39,900 / 0.082
Total copies sold= 486,585

Expand: -1/3(-2x-21)
Answer:
Step-by-step explanation:
Simplifying
3(2x + -1) = 21
Reorder the terms:
3(-1 + 2x) = 21
(-1 * 3 + 2x * 3) = 21
(-3 + 6x) = 21
Solving
-3 + 6x = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 6x = 21 + 3
Combine like terms: -3 + 3 = 0
0 + 6x = 21 + 3
6x = 21 + 3
Combine like terms: 21 + 3 = 24
6x = 24
Divide each side by '6'.
x = 4
Simplifying
x = 4
Answer:

Answer:
h = (3 - x)/2
Your answer is not correct.
Step-by-step explanation:
⅓(x + 2h) + 1 = 2
Subtract 1 from both sides;
⅓(x + 2h) + 1 - 1 = 2 - 1
This gives;
⅓(x + 2h) = 1
Multiply both sides by 3;
⅓(x + 2h) × 3 = 1 × 3
This gives;
x + 2h = 3
Subtract x from both sides to get;
2h = 3 - x
Divide both sides by 2 to get;
h = (3 - x)/2
