For this case we have the following inequality:

x + \frac {1} {2} x-3> 2

We add similar terms on the left side of the inequality:

\frac {2 + 1} {2} x-3> 2\\\frac {3} {2} x-3> 2

We add 3 to both sides of the inequality:

\frac {3} {2} x> 2 + 3\\\frac {3} {2} x> 5

We multiply by 2 on both sides:

3x> 5 * 2\\3x> 10

We divide between 3 on both sides:

x> \frac {10} {3}

The solutions are given by all values of x greater than \frac {10} {3}

Answer:

x> \frac {10} {3}

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the
Sever21 [200]

Answer:

The numbers are 24, 16 and 48

Step-by-step explanation:

For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.

88=x+(x+8)+3x

Now you simplify the equation,

88=5x+8

Now get the x and it’s coefficient alone on one side

80=5x

Now divide both sides so the x is alone

x=16

Since the second number was x you know the second number

the first number is x+8 since x is 16 the first number is 24

The third number is 3 * x so the third number is 48.

So the numbers are 24, 16 and 48

Simplify<br> (4x² – 2x + 8) - (x² + 3x - 2)
allochka39001 [22]

Answer:

3x² – 5x + 10

Step-by-step explanation:

(4x² – 2x + 8) - (x² + 3x - 2) =

Drop the first set of parentheses because it is unnecessary.

= 4x² – 2x + 8 - (x² + 3x - 2)

To get rid of the second set of parentheses, change every sign inside.

= 4x² – 2x + 8 - x² - 3x + 2

Now, combine like terms.

= 3x² – 5x + 10
