6=1/12v solve each equation. Check your solution
Answer:
112v=6 1 12 v = 6 . 12
Step-by-step explanation:
The solution to the equation is v = 72.
We have,
To solve the equation 6 = (1/12)v, we can follow these steps:
Multiply both sides of the equation by 12 to eliminate the fraction:
6 * 12 = (1/12)v * 12,
72 = v.
Therefore, the solution to the equation 6 = (1/12)v is v = 72.
To check this solution, we substitute v = 72 back into the original equation:
6 = (1/12)(72),
6 = 6.
Since both sides of the equation are equal, we can confirm that the solution v = 72 is correct.
Thus,
The solution to the equation is v = 72.

what is the greatest three-digit multiple of 33 that can be written using three different digits?
Please help me!!!
Answer:
957Step-by-step explanation:
The largest three-digit multiple of 33 * 30 is 990, which uses only two different digits. Now we work backwards: Subtracting 33 once gives 990-33=957, which has three different digits. Therefore, our answer is 957
957 is the greatest three-digit number which is multiplied by 33.
What are digits?A numerical digit is a single sign that can be used alone or in combination to denote a number in a positional numeral system.
A digit is a component of a set that, when put together, forms a numerical system.
Examples of digits include 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
If we multiply 33 by 31
It gives 1023 which is a four-digit number.
Now trying to multiply less than 31
By 30
33 × 30 = 990 but here two digits are the same.
By 29
33 × 29 = 957 and all three are different.
Hence "957 is the greatest three-digit number which is multiplied by 33".

Answer:
5/2
Step-by-step explanation:
Use PEMDAS to solve the equation in y=mx+b form.
Add 5x on each side of the = sign (which cancels on left side, and add on right)
Your equation should look like this: 2y=5x+10
Next, you're going to divide the whole equation by 2, to get y by itself

1. How many pounds of Brazilian Coffee should be mixed with 6 pounds of Colombian Coffee to get
mixture?
Answer:
12 pounds
Step-by-step explanation:
Colombian Coffee sells for $9.25 per pound. Brazilian Coffee sells for $7.75 per pound.
The management wishes to mix 6 pounds of Colombian Coffee with an amount of Brazilian Coffee so that the mixture sells for $8.25 per pound.
Hence:
Let the number of pounds of Brazilian coffee be represented by = a
$9.25× 6 + $7.75 × a= $8.25 (a + 6)
55.5 + 7.75a = 8.25a + 49.5
Collect like terms
8.25a - 7.75a = 55.5 - 49.5
0.5a = 6
a = 6/0.5
a = 12 pounds
Therefore, 12 pounds of Brazilian Coffee should be mixed with 6 pounds of Columbian nuts

six times a number decreased by 8 is less than five times the number plus 21
Answer:
6 ( or any number that isn't a common multiple of 5 and 6 ) you should probably double-check just in case.
Step-by-step explanation:
Question = 6x - 8 < 5x +21
so we know that the product of 6x must be divisible by 6 and 5x must be devisable by 5. so the first factor of 6 is 6 so:
(6 x 6) - 8 < (5 x 6) + 21
36 - 8 < 30 + 21
28 < 51
so x = 6
Honestly, any number would work because 6x is obviously more than 5x, but since for 6x you subtracting 8 and for 5x you adding 21 the answer will always be 6x - 8 < 5x + 21. Unless you use a common multiple of 6 and 5 as your x because then six times that number will always be more than 5 times that number. So for example 30 is a common multiple of 6 and 5 so:
(6 x 30) - 8 is more than (5 x 30) + 21
180 - 8 is more than 150 + 21
172 is more than 171
hope that helps : )
Representing the problem using mathematical equation, the inequality which represents the scenario is n < 29
Let the number be represented as n :
6n - 8 < 5n + 21
We can then solve for n
6n - 5n < 21 + 8
n < 29
Therefore, the inequality expression which represents the possible values of n for which the expression is true is n < 29

A music store marks up the instruments it sells by 30%. If the price on a trumpet says $104. How much did the store pay for it?
Answer:
A. $ 58.50
B. $ 80
C. No, it did not mark up 30%
Step-by-step explanation:
Since,
A. We have,
Mark up percentage = 30%
Actual price = $ 45,
B. We have,
SP = $ 104,
C. We have,
AP = $ 75,
SP = $100,
Thus, mark up percentage =
= 33.33 %
Hence, store did not mark up the price by 30%.
Answer:
$ 72.80
Step-by-step explanation:
30% of 104 = 0.30 * 104
= $ 31.20
Money paid by the store = 104 - 31.20
= $ 72.80
