Answer:
2.3 by 10^7
Step-by-step explanation:
We want this rewritten in the form 2.3*10^n.
To get the decimal point in 23,000,000 between the 2 and 3, we must move it 7 places to the left, and then compensate for this by multiplying 2.3 by 10^7.
Answer:
^algebra^
#1). a - b=4
a=4 + b .....(equation 1)
#2) a + b=12
(4 + b) + b= 12
4 + b + b=12
4 + 2b=12
2b= 12 - 4
2b =8
b= 8:2
b=4
subtituted b in equation 1
a= 4 + b
a= 4 + 4
a=8
so, the number is 8 and 4
