Question

Doing a test and I need to know these.

8 1/2-4 3/4

5/p=3/24

75% of 96

4x>12

6-(-4)

2.x=-10

4in/60mi= 10in/d mi

Answer 1

To do 4x> 12, you divide 4x by 4 to isolate variable then divide 12 by 4, because if you do something on one side you have to do on the other so... x= 3 ..hope that helped . Also 75% of 96 Its 72.. its just 75/100 = x/96 then use cross products to find out that
