Solve the compound inequality: 13 < 4x - 7 < 25

Step-by-step explanation:

This is just like an equation or compound equation, the only difference is that when multiplying or dividing by a negative #, to flip the inequality signs. You can either solve this equation by breaking it into to equations:

13 < 4x -7

and

4x-7 < 25

And then put it together...

... Or you can solve it as a whole. I am going to solve it as a whole

13 < 4x-7 < 25                 Given

13+7 < 4x-7+7 < 25+7     Addition Property of Inequality (Add 7 to all sides)

20 < 4x < 32                   What's left

20/4 < 4x/4 < 32/4         Division Property of Inequality (Divide by 4 on all sides)

5 < x < 8                          Answer

Therefore x must be 6 or 7.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
