7a - 2b = 5a + b
A. a = 2b
B. a = 3b
C. a =3/2 b
D. a =2/3 b
Ans.5) you can re-write 3 3/10 as 33/10
Now, you have to find two numbers whose sum would be 33/10.
Try to fix the denominator, and change numerator...like
it would be 13/10 + 20/10 or 15/10 + 18/10.Ok..
You can do your 6th ques. in same manner.

Answer:
x = 0.09
Step-by-step explanation:
Use the pythagorean theorum.
a^2 + b^2 = c^2
Plug in the values.
a^2 + 0.4^2 =0.41^2
= a^2 + 0.16 = 0.1681
Subtract to get a (which is the x value)
a^2 = 0.1681 - 0.16
a^2 = 0.0081
Square root 0.0081 to get a.
a or x = 0.09
