Step-by-step explanation:
The ratios are all 3 father steps to 5 son steps. Then ...
son-steps = 5/3·father steps
son-steps = 5/3·36 = 60
and
father-steps = 3/5·son-steps
father-steps = 3/5·30 = 18
___
As a <em>check</em>, you can realize that the numbers in the first blank, 36:60, are double those in the second blank, 18:30. The first of these, 36:60, is 3 times the row underneath it, 12:20.
Step-by-step explanation:
a) 8x + 5x = 13x
b) 9f + 10f - 12f = 7f

L = 16.51
Get variable onto one side of equation and simplify:
(−7.4 )+ L = 9.11
L = 9.11 + 7.4
L = 16.51
