I also recommend writing the polynomial as -6x^3y^2 5x^4-7z as it was a bit confusing to tell which numbers were the exponents.
If the total bill comes to $110.05, we know that we are going to have to take 15% of this for his tip.
So we convert 15% to a decimal by dividing by 100:
Then we multiply this by the amount of the bill:
So if we round this to the nearest cent, we get $16.51.
Therefore, Alberto's tip will be about $16.51.
So 1=6/8 minute
1=3/4 minute
multiply both sides by 4
4=3 minutes
3 times what=15
divide by 3
what=5
4=3 minutes
mulitpliy both sides by 5
20=15 minutes
answer is 20 bags

Answer:
Answers: 46, 23, and 111
Step-by-step explanation:
To answer, we need to know the angles. Therefore, give each angle a name. Angle 1 will be x, 2 will be y, 3 will be z. So, using this system of equations:
x=2y
z=y+88
x+y+z=180
Substituting, z = 1/2(x)+88, now plug z into the third equation:
x+1/2(x)+1/2(x)+88=180
this simplifies to 2x+88=180
subtracting 88 from both sides leaves 2x=92
x=46
plug this in to the first equation: 46 = 2y, so y = 23
plug this into the third one leaves z = 111
Hope this helps!
