20≤20
5 floors between her office and car
Answer:
The ordered pair is (2,3)
Step-by-step explanation:
we know that
If a system of equations has infinite solutions, then the equations are the same
we have
3ax+3y=5b -----> equation A
2x+y=5 ----> equation B
Multiply equation B by 3 both sides
3*(2x+y)=5*3
6x+3y=15 -----> equation C
Compare equation A and equation C
so
3ax=6x------> 3a=6 -----> a=2
5b=15 ------> b=3
The ordered pair is (2,3)
<h3>For 5 toppings, cost of tony and bob are same</h3>
<em><u>Solution:</u></em>
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
