Answer:
36 ft
Step-by-step explanation:
The ratio of the lengths of the sides is the same as the ratio of the perimeters.
Just like one side (15 ft) of triangle ABC is 3 times as long as the corresponding side (5 ft) of triangle DEF, the perimeter of triangle ABC is also 3 times the perimeter of triangle DEF.
15/5 = x/12
3 = x/12
x = 36
Answer: 36 ft

The system of equations is d+b=12 and 2.59d+5.49b=36.88 and Meaghan bought 10 packages of hot dogs and 2 packages of hamburgers.
Step-by-step explanation:
Cost of one package of hot dog = $2.59
Cost of one package of hamburgers = $5.49
Packages bought = 12
Cost of packages = $36.88
Let,
Packages of hot dogs = d
Packages of hamburger = b
According to given statement;
d+b=12 Eqn 1
2.59d+5.49b=36.88 Eqn 2
Multiplying Eqn 1 by 2.59

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 2.90

Putting b=2 in Eqn 1

The system of equations is d+b=12 and 2.59d+5.49b=36.88 and Meaghan bought 10 packages of hot dogs and 2 packages of hamburgers.
