Answer:
x = 2
Step-by-step explanation:
5x + 2 = 12
Subtract 2 from both sides
5x + 2 - 2 = 12 - 2
Simplifying
5x = 10
Divide both sides by 5
5x / 5 = 10/5
Simplifying
x = 2

Answer:
Step-by-step explanation:
apply the inverse properties of logarithmic and exponential functions to simplify
all logs has base 'e'
Inverse property of log says that
, the value of ln e=1
we apply this property in our problem. ln has same base 'e' . ln and 'e' gets cancelled
Answer:
80.
Step-by-step explanation:
When multiplying if the tenth place is " 7" then we look " next door" which is the ones and 8 is great then 5 so we count to from 8 to see when the next number ending in 0 would be in this case its 80. ( if the number is 4 or less count backwards to a number ending with 0 which in that case would have been 70 ) but the answer is 80.
