First you would simplify the equation <span>(7x²+2x+5)+(3x²-8x-10) lets start with the first part
</span><span>(7x²+2x+5)
</span>7x² + 2x which = 49x + 2x which also = 51x Then you add the last part (+5)
51x + 5
Now you simplify the last part.
<span>(3x²-8x-10)
</span>3x²-8x which=9x - 8x which also = 1x or simply x Then add the last part (-10) Which you'll get x-10
51x + 5) + (x - 10) = 52x -5
so your answer is 52x - 5
Lets x = the number of songs
The product of the number of songs and $0.99 = 0.99 times x = 0.99x
The product of the number of songs and $0.99 is $7.92:
=
0.99x = 7.92
Hope that helps.
20
This is because
2x+(6x+20)=180
8x+20=180
8x=160
8x/8=160/8
X=20
