Answer:
each hamburger costs $3.50
Step-by-step explanation:
he spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equaton,
2.50 + 3h = 13 now solve for x
-2.50 2.50
3h = 10.50
h=3.50
check:
2.50+3(3.50)=13
2.50+10.50=13
13=13
Answer: Should be A, 12 - i
Step-by-step explanation:
Got it from another website lol
Using the identity:
, we get:
There are two solutions to this equation:
1) Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2) Therefore, there are 3 solutions to the given trigonometric equation.
a) Let f be the cost of each ticket. We know that 2 tickets cost a total of $24.95, so therefore we have this equation:
2f = 24.95
b) Solve this equation by dividing both sides by 2:
f = 12.475
This value isn't possible with money so to make it realistic, we'll round to the nearest cent:
f = $12.48
c) We're ordering one more ticket, so we'll just add f to our total cost:
64.50 + f
= 64.50 + 12.48
= $76.98
