Let x = the number
6x + 12 = 8x
Subtract 6x on both sides of equation.
12 = 2x
Divide both sides of equation by 2.
6 = x
The number is 6.
Answer: 30% of 500 is 150.
Answer:
2, 3, 5
Step-by-step explanation:
The question asking for the linear equation Suzie manipulated. The answer should be equal to the starting equation. So, we just need to manipulate the option to y= mx + c format.
1. y + 7x = 23
y= -7x +23 (false)
2. . –7x + y = 23
y= 7x + 23 (true)
3. 2y – 14x = 46
2y= 14x+ 46
y= 7x +23 (true)
4. y – 7x = –23
y= 7x - 23 (false)
5. 7x – y = –23
-y= -7x -23
y= 7x + 23 (true)
So first find the factors of the denomenatores
14=2 times 7
7=7
21=7 times 3
common one would be having at least one 2, one 7, and one 3
find what numbers can be made by all of them
2 times 7 times 3
2 times 7
7
7 times 3
they are all in it
2 times 3 time s7=42
common denoomenator is 42
Answer:
We are dividing a slab of wood into equal pieces, so the obvious function would be to divide. And how long are the pieces going to be? 1/4 of a foot. so that gives us:
6 ÷ ¼.
Now, when we divide by a fraction, we flip the numerator and denominator and multiply, so the equation will look like:
6 * 4
Solve that, and you'll have your answer.
Step-by-step explanation:
Hope this answer helps you :)
Have a great day
