Answer:
0.84
Step-by-step explanation:
Use a calculator. That would be 0.84.
3*21

3/25 in 0.84 (so this answer checks out ok)
Answer:
= - 
Step-by-step explanation:
Given
=
( cross- multiply )
2(a - b) = 3(a + 2b) ← distribute parenthesis on both sides )
2a - 2b = 3a + 6b ( subtract 3a from both sides )
- a - 2b = 6b ( add 2b to both sides )
- a = 8b ( divide both sides by 8 )
-
a = b ( divide both sides by a )
-
=
