Answer:
(©) 1.05 x 10^5
Step-by-step explanation:
105,000.
Scientific notation is of the for a * 10^b
where a is a number between 1 and less than 10
move the decimal to make a be correct
1.05000
we moved it 5 places to the left, so b is 5
It is positive since we moved it to the left
1.05*10^5
We drop the zeros to the right of the 5

5x+2y=20
Substitute 0.3 for x
5(0.3)+2y=20
Multiply 5 by 0.3
1.5+2y=20
Subtract 1.5 from both sides
2y=18.5
Divide 2 on both sides
Final Answer: y= 9.25
