Answer: 6

Step-by-step explanation:

-\frac{2}{3}x+9=\frac{4}{3}x-3

Subtract \frac{4}{3}x from both sides to leave variables on the left.

-\frac{4}{3}x-\frac{2}{3}x+9=\frac{4}{3}x-3-\frac{4}{3}x

-\frac{4}{3}x-\frac{2}{3}x+9=-3

Now subtract 9 from both sides to isolate independent variables on the right.

-\frac{4}{3}x-\frac{2}{3}x+9-9=-3-9

-\frac{4}{3}x-\frac{2}{3}x=-3-9

Combine like terms;

-\frac{6}{3}x=-12

Simplify;

-2x=-12

To completely isolate x, divide by -2

\frac{-2x}{-2}=\frac{-12}{-2}

x=6

Solve the proportion: 5/x+7=3/x+3
Allushta [10]

Answer:

x=3

Step-by-step explanation:

cross multiply

5(x+3)=3(x+7)

5x+15=3x+21

5x+15-3x=3x+21-3x

2x+15=21

2x+15-15=21-15

2x=6

x=3

How many three-digit phone prefixes that are used to represent a particular geographic area are possible that have no 0 or 1 in
Sonbull [250]

Answer:

The number of possible three-digit phone prefixes that are used to represent a particular geographic area is 640.

Step-by-step explanation:

The phone prefixes used to represent a particular geographic area are a 3 digit code consisting of numbers from 0 to 9.

The prefix code are of the form: <u>x</u> <u>x</u> <u>x</u>

Condition: The first or the second place cannot take values 0 or 1.

Then the first place can be occupied by the remaining 8 digits.

Similarly the second place can also be occupied by the remaining 8 digits.

And the third place can be occupied by any of the 10 digits.

So the number of ways to construct a phone prefix for any area is:

Possible\ number\ of\ phone\ prefixes=8\times8\times10=640

Thus, the number of phone prefixes possible for any area is 640.

What is an absolute value? What does it do? When would we need to use an absolute value
Nana76 [90]
Absolute Value Absolute Value means ...

... only how far a number is from zero:

<span> <span><span> </span> <span> <span> "6" is 6 away from zero,
and "−6" is also 6 away from zero. So the absolute value of 6 is 6,
and the absolute value of −6 is also 6 </span> </span> </span></span>

More Examples:

<span><span>The absolute value of −9 is 9</span><span>The absolute value of 3 is 3</span><span>The absolute value of 0 is 0</span><span>The absolute value of −156 is 156</span></span> No Negatives!

So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive (or zero).

Absolute Value Symbol

To show that we want the absolute value of something, we put "|" marks either side (they are called "bars" and are found on the right side of a keyboard), like these examples:

<span> <span><span> |−5| = 5 |7| = 7 </span> </span></span> Sometimes absolute value is also written as "abs()", so abs(−1) = 1 is the same as <span>|−1| = 1</span>
