I think you meant 3([7/5]x + 4) - 2(3/2 - [5/4]x). If that's the case, then identify the LCD: It is 20. Multiply both [7/5]x + 4 and 3/2 - [5/4]x by 20 and then divide the resulting expression by 20:

3(28x + 80) - 2(30 - 25x)

------------------------------------

Next, perform the indicated multiplication:

84x + 240 - 60 + 50x

----------------------------------

This simplifies to:

34x + 180 17x + 9

---------------- = ----------------

20 10

Next time, please share the answer choices.

How many times does 1/4 go into 9/16

Monica [59]

Answer as a fraction = 9/4

Answer in decimal form = 2.25

================================================

Explanation:

1/4 = 4/16 after multiplying top and bottom by 4

We have some number x such that

(4/16)x = 9/16

we can multiply both sides by 16 to clear out the fractions, getting 4x = 9

Then we divide both sides by 4 to get x = 9/4 = 2.25
