Answer:
The answer would be, 0.50 50 ones would go before the decimal sign.
Step-by-step explanation:
The expression for y in terms of "a" when value of x is doubled is 
<em><u>Solution:</u></em>
Given that,
y is directly proportional to 
Therefore,


Where "k" is the constant of proportionality
y = a for particular value of x
Therefore,
--------- eqn 1
We have to find when x is doubled
x is doubled means 2x
Let it be 
Hence we get,
--------- eqn 2
Substitute value of k from eqn 1, we get

Thus expression for y in terms of "a" when value of x is doubled is 
Answer:
∠BFA = 75º
Step-by-step explanation:
First, let's add the three angle degrees provided.

Then, we subtract 135 from 360º, which is all the angles added together.
360º - 135º = 225
Since ∠BFC is 2xº, then we have to divide 225 by 3.

∠BFC is twice the amount of x, so ∠BFC is 75 * 2 = 150º
xº is 75º
To check our answer, we can add all these angles and if they add up to 360º, we are correct.
30 + 45 + 60 + 75 + 150 = 360º :)
