400gr is 0.4 kg
so 6*0.4=2.4 dollars
Answer: 400grams cost 2.4 dollars
F(x) - g(x) = 3x + 2 - (6x-7) = 3x + 2 - 6x + 7 = -3x + 9;
There is no answer correct!
Answer: -48m + 56
Step-by-step explanation:
-8x 6m= -48m
-8x-7= 56
Bench = x
garden table = x-78
Set up an equation
x + x-78 = 872
Solve for x
2x-78 = 872
2x = 950
x = 475
So, the bench itself costs $475.
