Answer:
B is the answer 12x^3 - 6x^2 +6x +8
The system of equations best represents the number of apples a and the number of garonia bars g be a+b=60, 0.75x+0.15y=21.
Given that cost of 1 apple is $0.75, cost of 1 gargonia bars be $0.15 ,total things are 60 and total money paid be $21.
Equation is relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be a linear equation,quadratic equation, cubic equation.
Because we have been told that there are 60 total things and a represents the number of apples and g represents number of garonia represents the number of garonia bars.
a+b=60--------1
Money paid by consumers is cost per units*number of units
So,
0.75a+0.15b=21
Hence the system of equations best represent the number of apples and the number of garonua bars g are a+b=60, 0.75a+0.15b=21.

The correct answer is A.
Each y value is equal to -4 times the x value.
-4*-4=16
0*-4=0
4*-4=-16
8*-4=-32
Answer:
x=2.97
Step-by-step explanation:
Answer:
2y + ( x- 20)= 500
y= 520-x/2
Step-by-step explanation:
Let the weight of George be x and the weight of the suspect be y .
The swing can hold a maximum of 500 pounds .
Twice the weight of suspect added with 20 pounds less than the weight of George equals 500.
2y + ( x- 20)= 500
or
2y+x- 20 = 500
adding 20 to both sides
2y+x -20 +20= 500+ 20
or
2y +x = 520
Subtracting x from both sides
2y+ x-x = 520-x
or
2y = 520-x
Dividing by 2 on both sides
y= 520-x/2
The suspect's weight is y= 520-x/2
