Answer:
B
Step-by-step explanation:
She should chose the $9 because it is cheaper ;)
There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. <span />
X = tuna, y = BLT
x + y = 30
6x + 9y = 240
3y = 60
y = 20
x = 10
20 BLTs for $2.50, 10 tuna for $1.50
Answer:
3x²+11x+20
Step-by-step explanation:
x(3x+5)+2(3x+5)
3x²+5x+6x+20
3x²+11x+20
