tony's hambugers shack sells hamburgers for $2 plus.40 for each topping

bob's burgers sells hambugers for $3 dollars plus .20cents for each topping

solve the system equations using the equal value method
pls writte the steps

Solution:

Let "x" be the number of toppings

Given that,

Tony's hamburgers shack sells hamburgers for $2 plus $0.40 for each topping

Therefore,

Cost = 2 + 0.40x eqn 1

Bob's burgers sells hamburgers for $3 dollars plus 20 cents for each topping

20 cents = $ 0.2

Therefore,

cost = 3 + 0.2x eqn 2

For both the cost to be same, eqn 1 is equal to eqn 2

2 + 0.40x = 3 + 0.2x

0.40x - 0.2x = 3 - 2

0.2x = 1

Divide both sides by 0.2

x = 5

Thus, for 5 toppings, cost of tony and bob are same

the perimeter is increased by a factor of 2

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
