Answer: C
Step-by-step explanation:
Schoool suckkks
4x + y = 54
8x + 2y = 104
8x + 8y - (8x + 2y) = 240 - 104
6y = 136
y=22 2/3
4x+ 22 2/3 = 54
4x= 31 1/3
x= 7 5/6
Answer:
$522.60
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost
24.60 + 78 + 420 = 522.60
1) calculate 12% of 3000
3000=100%
x=12%
3000•12=100•x
x=360
2) calculate 3% of 3000
3000=100%
y=3%
3•3000=100y
y=90
3) calculate 1% of 3000
3000=100%
z=1%
3000•1=100z
z=30
4) calculate 6% of 3000
3000=100%
k=6%
3000•6=100k
k=180
5) now we need to add all this numbers to each other to see total money he has to spend in taxes (but we will take 180 twice because there where two 6%_s)
360+90+30+180+180=840
6) to calculate his take-home pay, we need to subtract 3000 by tax pay that we just calculated
3000-840=2160
FINALL ANAWER—his take home pay is $2160
The equation a line is:
y - y1 = m(x - x1)
Substitute the slope and the coordinate.
y - (-7) = -23(x - 1)
y + 7 = -23(x - 1)
D) y + 7 = -23(x - 1) is the solution
