Answer:
b = 45.9 - c
Step-by-step explanation:
A scalene triangle has non of its sides equal.
Perimeter = 54.6
side a = 8.7 cm
side b = unknown
side c = unknown
Perimeter of a shape is sum of all its sides.
Perimeter = a + b + c
54.6 = 8.7 + b + c
Making b the subject
b = 54.6 - 8.7 - c
b = 45.9 - c
The value of b is (45.9 - c)

Answer:
35
Step-by-step explanation:
Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.
Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.
- v + 3.40c = 266.20
- v + c = 103
Subtract these equations.
Divide both sides by 2.40.
Substitute this value for c into the second equation.
Subtract 68 from both sides.
The number of vegetarian wraps sold amounted to 35 in total.
