How can properties help me divide?

whitney says that to add fractions with diffrent denominatros, you always have to multiply the denominators to find the common unit;for example 1/4 1/6=6/24 4/24 Show whitney how she could have chosen a denominator smaller than 24,and solve the problem?

Answers

You could multiply 1/4 by 3 and 1/6 by 2. You would get 3/12 and 2/12. The common denomonator is 12. 4 and 6 are both multiples of 12.

Simplify the expression 2x+3(x-2)-3(x-6)

A. 2x + 12
B. 2x - 8
C. 8x - 24
D. 2x - 24

Answers

2x+3(x-2)-3(x-6) \n \n 2x + 3x - 6 - 3x + 18 \ / \ expand \n \n (2x + 3x - 3x) - 6 + 18 \ / \ gather \ the \ like \ terms \n \n 2x - 6 + 18 \ / \ simplify \n \n 2x + 12 \ / \ simplify \n \n

The final result is A) 2x + 12.
2x+3(x-2)-3(x-6)You would first distribute.So:2x+3x-6-3x+18Then you would combine like terms, like so:2x+3x-3x= 2x-6+18= 12So it'd be:2x + 12Which is answer choice AHOPE THIS HELPS!!(:

how many minutes is it before 12 noon if 20 minutes ago it was three times as many minutes after 9 am

Answers

First, change everything into minutes.
12 noon is 12 by 60 which = 720 minutes.
9am is 9 by 12 which = 540 minutes.
X is now your number of minutes before noon.So noon - x is the next step:
720 - x
20 minutes ago it was 720 - x - 20
720 - x - 20= 540 + 3x (3x because you're looking for 3 times as many minutes)
720 - 20 - 540=4x (you combine all the like numbers and variables) 
160 = 4x
160/4= x
40 = x
Your answer is 40 minutes

How do I solve this equation? If 3t-7=5t then 6t=

a 21
b-7
c-21
d-42

Answers

If 3t – 7 = 5t, then 6t =
Let’s first solve the first equation:
=> 3t – 7 = 5t
=>  3t – 5t = 7
=> -2t = 7
=> t = 7 / -2
=> t = -7/2

If t = -7/2 , then 6t = 6 (-7 / 2)
=> t = -42/2
=>  t = - 21 Thus, the value of t in If 3t – 7 = 5t is -7/2
and the value of t in 6t = is -21
The answer is C.
