Answer:
38°
Step-by-step explanation:
Using the Cosine rule in Δ ABC
cos A = 
where a, b and c are the sides of the triangle.
Here a = 5, b = 3 and c = 7 , thus
cos A = 
= 
= 
, thus
∠ A = 
( ) ≈ 38°
The answer would be about 98 hamburgers.
This is because you would have to divide 393 by 2 to get 196.5.
Since the number of cheeseburgers is doubled divide 196.5 by 2 to get 98.25.
Add 98.25 to 196.5 and get 294.75.
Subtract.
Answer:
it would take her 42 mins
Step-by-step explanation:
In this equation x = 49.
In order to find this, follow the order of operation of solving equations.
1/7x - 5 = 2 -----> Add 5 to both sides
1/7x = 7 ----> Multiply both sides by 7
x = 49
