Answer:
b) 7.89*10^4
c) 3.15*10^3
Step-by-step explanation:
2-42)
the coefficient in scientific notation (the number that is not 10^x) has to be greater or equal to 1 and less than 10. so c and b are incorrect.
b) 0.789*10^5
c) 31.5*10^2
b) 0.789*10^5
in order to make 0.789 greater than 1, I would just multiply it by 10. shown below
=0.789*10*10*10*10*10
=7.89*10*10*10*10
=7.89*10^4
c) 31.5*10^2
same concept but this time divide by 10 to make 3.15 which will add another *10 to the exponent
=31.5*10*10
=3.15*10*10*10
=3.15*10^3

Answer:
Step-by-step explanation: square root both numbers so 55 square root is 7.41 and he square root of 16 is 4 now divide them so 7.41 divided by 4 = to 1.85 there fore 1.85 is ur answer
Multiply eqn 1 by 3 and eqn 2 by 7 then adding them will cancel Y. and X can be found.
