1. <u><em>a=-1+b/7 is the right answer.</em></u> First you had to add by b from both sides of equation, and it gave us, 
. And then simplify, and it gave us, 
. Divide by 7 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is a=-1+b/7 is the right answer.

2. <em><u>a=-b-1/2 is the right answer.</u></em> First you had to add by 2b from both sides of equation, and it gave us, 
. And then simplify, and it gave us, 
. Next you can also divide by -4 from both sides of equation, and it gave us, 
. Finally simplify, and it gave us the answer is a=-b-1/2 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

As the moon's diameter is straight, the distance from the observer to the moon and the diameter are at 90°, subtending an angle at the viewer's eye. This is:
tan∅ = diameter / distance
tan∅ = 2160 / 238,860
∅ = 0.52°
The answer would be C. 0.928.

The question is asking what the income is and what the rest amount is
We are told that 75% of the income is Rs. 9000
Le the income be x
so
75/100*x=9000
0.75x=9000
x= 9000/0.75
x=12000
Hence the income is
Rs. 12000
The rest amount
=12000-9000
=Rs. 3000
