Answer:
32 foot-long hot dogs will be served
Step-by-step explanation:
The total number of "ratio units" is 3+2 = 5. If 5 units stand for 80 hot dogs, then each ratio unit represents 80/5 = 16 hot dogs.
The number of foot-long hot dogs that will be served is 2×16 = 32.
3y + 3x =24
6y+3x = 39
Answer:
x = - 2
Step-by-step explanation:
Given
y = 4x² + 16x - 18
with a = 4, b = 16 , then the equation of the axis of symmetry is
x = - = - = - 2
- 3y + 7 + 3(y-1) = 2(2y+6)
- (x-5)(x+4) = (x+7)(x-6)
- 2(x+1)2(x-2)2 = x(x-3)
