4 packages of hot dogs and 5 packages of hot dog buns.
Step-by-step explanation:
Find the least common multiple of 10 and 8, which is 40.
Answer:
Step-by-step explanation:
sin x=a+b
cos x=a-b
sin²x+cos²x=(a+b)²+(a-b)²=2a²+2b²
or 2a²+2b²=1
a²+b²=1/2 which is constant for all values of x
(ii)

1. 6a-2b+4
2. 3a-3b+9
3. -2x-8=-10
-2x=-2
X=1
4. -x+4=5
-x=1
X=-1
6 x 10% = 0.6
6-0.6=5.4
the cake costs $5.40 after the discount
