Given statement is "You download 12 new songs to your MP3 player. then you delete 5 old songs."
We have to write each amount as an integer.
Download 12 new songs means you are adding number to your MP3 player so we will use + sign for 12
So the amount in integer form will be +12
Ddelete 5 old songs means you are subtracting number from your MP3 player so we will use - sign for 5
So the amount in integer form will be -5
combining both expressions we can write final statement as:
+12-5
Which can be simplified to +7.
There's a property of logs I want you to remember, that is:
log(a)ᵇ = b*log(a)
We'll be using this property to solve the question
<u>Finding x:</u>
log(2)ˣ = log(3)
x*log(2) = log(3) [using the property mentioned above]
x = log(3) / log(2) [dividing both sides by log(2)]
Hence, the correct answer is option E.
Answer:
Correct
Step-by-step explanation:
Answer:
x > 3
Step-by-step explanation:
-17x + 2 < -10x - 19
_____________
.Subtract 2 from both sides.
-17x + 2 - 2 < -10x - 19 - 2
____________________
.Simplify.
-17x < -10x - 21
__________________
.Add 10x to both sides.
-17x + 10x < -10x - 21 + 10x
____________________
.Simplify.
-7x < -21
_________________
.Multiply both sides by -1 (reverse the inequality).
(-7x)(-1) > (-21)(-1)
______________________
.Simplify.
7x > 21
_______________________
.Divide both sides by 7.
7x/7 > 21/7
_____________________
.Simplify.
x > 3
Answer:
x = -4/5 = -0.800
Step-by-step explanation:
Pull out like factors :
-12 - 15x = -3 • (5x + 4)
Solve :
-3 = 0
Solve :
5x+4 = 0
5x = -4
<u><em>x = -4/5 = -0.800</em></u>
