Y divided by 9 equals 81
Answers
The solution to the equation "Y divided by 9 equals 81" is Y = 729.
To solve the equation "Y divided by 9 equals 81,".
we can multiply both sides of the equation by 9 to isolate the variable Y:
(Y/9) × 9 = 81 × 9
On the left side, the 9s cancel out, leaving us with just Y:
Y = 81 × 9
Multiplying the numbers on the right side, we get:
Y = 729
Therefore, the solution to the equation "Y divided by 9 equals 81" is Y = 729.

Answer:
729
Step-by-step explanation:
In order to solve this, you need to do the reverse operation. The question is about division, so that means we are going to do multiplication. If we multiply 9x81, we will know what divided by 9 equals 81.
9x81=729
So 729 divided by 9 equals 81.
To check this just plug the number you got back into the orignal equation:
Y divided by 9 equals 81
729 divided by 9 equals 81

The number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
It is given that Karli and her friend can paint 6/7 of a picture in 3/14 of an hour.
Let's assume they can paint x number of pictures in a full hour.
So , the fraction by dividing 6/7 by 3/14 can be written equal to x .
i.e.,
= x
We need to do the cross product here :
× x =
or
x = () ÷ (
)
We know that when dividing two fractions we need to change the division sign to multiplication sign by inverse the fraction value right to the division sign i.e.,
x = () × (
)
x = 84 / 21
x = 4
Therefore , the number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

Answer:
4 pictures
Step-by-step explanation:
(6/7)/(3/14)=x/1
cross product
3/14*x=6/7*1
3/14x=6/7
x=(6/7)/(3/14)
x=(6/7)(14/3)
x=(6/1)(2/3)
x=12/3
x=4

5z = 40
divide both sides with 5
z = 8
The reason i know this is:
5z-8=32 add 8 to both sides
5z - 8 = 32
+ 8 +8 (the -8+ 8 get taken off.)
So you have left
5z=40
divide
5z = 40
---- ------
5 5
the 5's get crossed out
and divide 40 by 5 and you'll get 8 :)
If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.
If both workouts were 60 minutes, Dane spent 8 more minutes on cardio exercise than Alina did.
Alina spent less time on cardio exercise than Dane did.
Answers
Answer:
If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.
Step-by-step explanation:
For option A,
If they both workout for minutes,
Alina's time is
and Dane's time is
The difference is
If they both work out for 100 minutes, then Dane did 10 more minutes of cardio exercise than Alina.
Since is not fixed, this statement is false.
For option B,
If Alina's work out was 80 minutes, then she spent minutes on cardio exercise.
If Dane's work out was 48 minutes, then he spent minutes on cardio exercise.
Hence both spent the same amount of time on cardio exercise.
The correct answer is option B
For option C,
If they both workout for minutes, then
Alina's time is
and Dane's time is
The difference is
If they both work out for 60 minutes, then Dane did 9 more minutes of cardio exercise than Alina and not 10.
This statement is false
For option D,
We cannot tell whether Alina spent more or less time than Dane,unless we know the time both spent for the entire work out.
Next, #3 is also not right since the difference is way to great.
Next, #4, we cannot tell how long the workouts of both were, so this is not right either
Therefore, #2 is the right answer
Hope this helped!! :D

Examples:
Example 1:
2-4(3x+5) --- distribute the -4 to the 3x+5 to get...
2-12x-45 ---- do 2-45
-43-12x
and that's your answer since you can't combine the -43 with the -12x cuz, the -43 does have a variable.
Example 2:
5y+4-2y ---- so simplify first. 5y-2y. to get...
3y+4
and that the answer
cuz you can't combine a number with a variable(letter. y, x, etc.) with one that doesn't.
I hope this helps. This is easy. Trust me. if you still don't get it. Just comment. Hope this helps! :)
