Extra math help example problem


Example:

Solve the inequality -3< 4(x+2)-3<17 br="">
Solution:

Given inequality is

-3< 4(x+2)-3<17 br="">
Multiplying the factor values for equation

-3<4x br="">
-3<4x br="">
Subtract value 5 on both sides of equation

-3-5<4x br="">
-8<4x br="">
Divide by 4 for all terms

-2
Conclusion:

The solution consists of all real number the interval (-2, 3)

Example:

Seven men 9 hours need to complete a particular job. Calculate how long it takes 10 men to do the job they work at the same rate?

Step 1:

Let the given problem as If 7 men then 9 hours need. If 10 men then how many hour need to complete the job

Step 2:

The inverse proportional relationship:

7 => 9

10 =>7 / 10 x 9

=> 63/10

=>6.3 hours

Answer:

They will take to complete the job in 6.3 hours.

Example:

Solve the x for the equation.

2(2x - 2) + 2x = 4(2x + 2)

Solution:

Multiplying factor 2 with (2x-2) and 4 with (2x+2)

4x - 4 + 2x = 8x + 8

Subtract 2x on both side of equation

4x - 4 +2x-2x= 8x -2x+ 8

4x - 4 = 6x+8

Subtract 6x on both side of the equation

4x-6x-4 = 6x-6x+8

-2x-4=8

-2x=8+4

-2x=12

Simplify the x value

x =12/-2

x = -6

Answer:

x = -6
