Answer: 253.5
Step-by-step explanation:
Each roast beef cost $4 and each vegetarian sandwich cost $2.5
Let x represent the cost of each roast beef and let y represent the cost of each vegetarian sandwich.
Bhargav buys five roast beef and three vegetarian sandwiches and the order costs $27.50. This can be represented by the equation:
5x + 3y = 27.50 (1)
Bhargav buys 2 roast beef and 6 vegetarian sandwiches and the order costs $23.00. This can be represented by the equation:
2x + 6y = 23.00 (2)
To find x and y, we have to solve equation 1 and 2 simultaneously. Multiply equation 1 by 2 and subtract equation 2 from the result:
8x = 32
x = 4
Put x = 4 in equation 2
2(4) + 6y = 23.00
6y = 15
y = 2.5
Therefore each roast beef cost $4 and each vegetarian sandwich cost $2.5

Area of the pentagon: 342 cm2
Step-by-step explanation:
The figure of the pentagon is missing: find it in attachment.
The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,
L = 14.1 cm
and the height of each triangle can be found by using Pythagorean's theorem:
The area of each of the 5 triangles is
Therefore, the area of the pentagon is 5 times this area:
