Answer:

x=-1 y =-1

multiply equation 1 with (-2)

+6x-2y=-14

5x+2y=3

now add equation 1 to equation 2

11x=-11

x=-1

now substitute x=1 in 1 or 2

5(1)+2y=3 5+2y=3 2y=3-5 2y= -2 y= -1

While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite

Hoochie [10]

You would spend $63.58 on gas per week.

Step-by-step explanation:

Given,

Distance per day = 117 km

Distance in a week = 117*7 = 819 km

1 km = 0.6214 mile

819 km = 819*0.6214 = 508.93 miles

Car's mileage = 42.0 mi/gallons

Let,

x be the gallons for 508.93 miles

x gallons = $\frac{508.93}{42}=12.12$

Therefore,

12.12 gallons of gas is needed for one week.

1 US gallon = 3.785 liters

12.12 gallons = 12.12*3.785

12.12 gallons = 45.87 liters

Cost of gas per liter = 1.10 euro

Cost of 45.87 liters = 1.10*45.87 = 50.457 euros

1 euro = $1.26

50.457 euros = 1.26*50.457 = $63.58

You would spend $63.58 on gas per week.
