2x minus 3/4 = 15/4 what is the x

mihalych1998 [28]

2x - (3/4) = (15/4)

We need to get x by itself. First add 3/4 to both sides.

2x = 18/4

Now divide both sides by 2

x = 18/8 or 9/4

Veseljchak [2.6K]

Answer:

19: The difference between the temperature in Fair Banks and Barlow is 3°F

20: -13°F, -10°F, 15°F, 24°F.

Step-by-step explanation:

I'm assuming that by "compare", it means to find the difference between temperatures in question 19. If it means something else, let me know and I'll try and help you find it.
