Hey there! I'm happy to help you! :)
We see that there are 160 songs in total. Let's split them up into groups of rock, country, and pop.
ROCK
Our problem says that 3/8 of the songs are rock songs. We know that we have 160 songs. We just need to multiply 3/8 by 160 and we will have the number of rock songs.
3/8*160=60
Therefore, we have 60 rock songs.
COUNTRY
We see that 25% of our songs are country songs. 25% is the same thing as 1/4, or 0.25. We can multiply this by our total number of songs to see how many are country.
0.25(160)= 40
We have 40 country songs.
POP
All we have in the problem is that the remaining songs are pop. The nice thing is is that we already know how many rock and country songs we have, so we can simply subtract those from 160 and we will then be able to tell how many pop songs there are.
160-60-40= 60
Therefore, there are 60 pop songs.
I hope that this helps you! Have a wonderful day!

In any equation with variables, you want to end with a variable isolated on one side with no coefficients(like x=4, for instance).
So, with that in mind, let's solve number 2.
5(x-3) - 2(2x+4) = -2(x-2)
Let's distribute the coefficients.
(5x-15)-(4x+8) = (-2x+4)
Simplify the left side first (by subtracting the two)
5x-4x = x
-15 - (+)8 = -23
So, left side is
x-23 = -2x+4
We're close now, just bring the x to the left side and the other values to the right
x-23 = -2x+4
+23 +23
x=-2x+27
+2x +2x
3x=27
divide by 3
x=9
3.
3(4x-5)-2(2x-2)=4(3x-2)+5
Same idea here; distribute the coefficients, and simplify.
(12x-15)-(4x-4)=(12x-8)+5
12x-4x=8x
-15-(-)4=-11
-8+5=-3
8x-11=12x-3
bring x to left, other numbers to right
-12x -12x
+11 +11
-4x = 8
divide by -4
x=-2
Answer: The answer you're looking for is 1.75.
Hope this helps
Answer:
It B.(6.25,-5)
Step-by-step explanation:
You should multiply G.(2.5,-2) times 2.5, like this (2.5*2.5,-2*2.5) equals (6.25,-5)
