Answer:
Step-by-step explanation:
I will take a to be 52.6 * 10^-9 The number should be 5.26 * 10^-8 so A is not the answer.
6.39*10^9 This one is correct.
0.12 * 10^-2 is not correct. It should be 1.2*10^-3
10 * 10 ^7 should be 1*10^8 so D is not correct.
The coefficient of scientific notation must be a number between 1 and 10 and including 1 but not 10. This is written as 1 ≤x <10
A lot of money because then they get even more back
you mean : 5/8x + 1/16x = 5/16 +x
<=> 10/16x +1/16x = (5 +16x)/16
(16x # 0)
<=> 11/16x = x(5+16x)/(16x)
<=>11 = x(5+16x)
<=> 11 = 16x^2 + 5x
<=> x =-1 or x =11/16
Answer:
do the following
Step-by-step explanation:
subtract the 2nd equation from the 1st....
x-2y = 14
-(x+ 3y = 9)
______________
-5y=5
y= -1
since you know that y is = to - 1 pick the 3rd answer
