Step-by-step explanation:
Answer:
-m+4
Step-by-step explanation:
The first one is not proportional and the second one is proportional.
8.5 as a fraction is 8.5/1. To make the denominator 4, you must multiply both the top and bottom by 4 (4x8.5/1x4). This gives you your answer, which is 34/4. To double check this, you just divided 34 by 4. This equals 8.5, which is the original number.
2x+1=5x-20
you want to find the x value so you want to isolate x to do this you have to subtract 2x on both sides. After you have accomplished this you add 20 on both sides once again and then you divide what your answer from what you added by three.
2x+1=5x-20
-2x -2x
________
1=3x-20
+20 +20
_______
21/3=3x/3
7=x
