I guess the number 2 is to indicate the question...
Then the equation would be 1/3 - 1/2x = -2/3
1/3 - 1/2x - 1/3 = -2/3 - 1/3
-1/2x = -3/3
-1/2x = -1
-1/2x *2 = - 1*2
-x = -2
-x * -1 = -2 * -1
x = 2
Good luck
<span>Total households = 127,900,000
Proportion of households having remote control and not
7 : 3
7x + 3x = 127,900,000
10x = 127,900,000
x = 12,790,000
Households having remote control = 7x
= 7 X 12,790,000
= 89,530,000
Answer:
89,530,000 households have TV remote controls.</span>
Answer: Find the greatest common factor, and put in parentheses outside of the expression
Step-by-step explanation:
The greatest common factor is the largest number that all terms are divisible by. Here is an example: 4x+8y+12 In this example the greatest common factor is 4. So, first we divide the expression by 4 and put it in parentheses, giving us (x+2y+3). However, (x+2y+3) does not equal 4x+8y+12. We need to put the 4 we divided by in front of the parentheses, giving us 4(x+2y+3), which does equal 4x+8y+12. Hope this helps
