Answer:
m-3 years old
Step-by-step explanation:
For scientific notation, you always want 1 digits in front of the decimal.
Ex) 7.39*10^5
Move the decimal point in between the 1 and 4, or 1 place to the left.
1.435
Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.
1.435*10^1
1.435*10^1 is your final answer.
1.435*10 is the same thing also.

Answer:
Step-by-step explanation:
1 12
2 19
3 10
4 28
5 2
2j+6a = 24
5j+3a =21
multiply the 2nd equation by -2
-10j -6a = -42
add the 1st and the modified 2nd together
2j+6a = 24
-10j -6a = -42
---------------------
-8j = -18
divide by -8
j = 2.25
substitute into
2j+6a = 24
2(2.25) +6a =24
4.50 +6a =24
subtract 4.5 from each side
6a = 19.50
divide by 6
a = 3.25
