Answer:
x-13
Step-by-step explanation:
why you may ask?
subtracted=being taken away from
13 is *being taken away from* x
so if using numbers, 13 is being taken away from 20
or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

How do you convert mass to volume without density?
Answer:
Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be
The general formula is:
ρ
=
m
V
where
ρ
is density in
g/mL
if mass
m
is in
g
and volume
V
is in
mL
.
So to get the mass...
m
=
ρ
V
Or to get the volume...
V
=
m
ρ
When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.
Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.
These days, you should be able to search for the density of any common object.
When you have the density and volume but not the mass, then just make up a mass.
You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
Don't guess!

What is the exact circumference of a circle that has a radius of 10 cm?
Answer:
C = 20π cm
Step-by-step explanation:
If you want the "exact circumference," use π instead of the usual approximation 3.14 or 3.14159.
Here the circumference is C = 2π(10 cm), or C = 20π cm.

$5000 at 10% for 3 years. Compound Interest.
6% $5,955
8% $6,299
10% $6,655
12% $7,025
Please help me if you can. Please also write how you got the answer thank you.
First state your variables:
a = Andile
Everything is related to Andile and therefore we do not need to make this equation more difficult by adding in more variables.
a + (a - 40) + 2(a - 40) = 380
Expand brackets and simplify:
2a - 40 + 2a - 80 = 380
4a - 120 = 380
4a = 500
Then solve for 'a' by dividing by both sides:
a = $125
Now we know Andile's pay we can find Taylor's quite easily:
t = a - 40
t = 125 - 40
t = $85
Taylor earned $85.
Please mark as brainliest :)
Hope this helps :)))

Answer:it a
Step-by-step explanation:
the answer is c because the definition of multiplicative inverse is :
In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number.

Answer:
By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)
Step-by-step explanation:
The formula for 90 degree clockwise rotation is
(x,y)--->(y,-x)
The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.
Hope this helps!
I'll leave the rest of the formulas I have in my notes for you!
180 degree rotations
(x,y)--->(-x,-y)
90 degree counterclockwise
(x,y)--->(-y,x)
270 degree rotation
(x,y)--->(y,-x)
A pretzel stand at the state fair sells 3 pretzels for $6.75, 6 for $13.50,
and 9 for $20.25. What is the most likely cost for 15 pretzels?
A $27.00 B $33.75
C $40.50 D $46.75
Answer: B
Step-by-step explanation:
Since 9 is 20.75 just add 6.75 each time you add 3 so 9--> 12 = 27.00
12--> 15 = 33.75
Answer: B
Step-by-step explanation:
Since 9 is 20.75 just add 6.75 each time you add 3 so 9--> 12 = 27.00
12--> 15 = 33.75

POD: 4 (2a + 3) = 28
Answer:
a = 2
Step-by-step explanation:
4 (2a + 3) = 28
4 * 2
= 8
4 * 3
= 12
8a + 12 = 28
28 - 12
= 16
8a = 16

Eve wants to buy a balance beam. The original price is $388. How much will Eve pay if she buys it during the sale? It was on sale for 75%!
Answer:
Eve will pay $97 if she buys it during the sale.
Step-by-step explanation:
price during sale = original price - (original price * discount percentage)
disc. % = 75%
75% = 0.75
pr. = 388 - (388 * 0.75)
pr. = $97
