Answer:
r=0.5
Step-by-step explanation:
0.125r+0.25r-0.0625=0.25+r
0.375r-0.0625=0.25+r
0.375r-r=0.25+0.0625
-0.625r=0.3125
r=0.3125/0.625
r=0.5

Answer:
2 should be distributed as 2y + 16; y = 8
Step-by-step explanation:
 We have to distribute 2, then:
 Now we have to sum (-2y) in both sides of the equation:
Finally we have to divide both sides of the equation in 2:
Then the answer is 2 should be distributed as 2y + 16; y = 8
Hope this helps.
