To convert £280 at the post office exchange rate of £1=€1.17, you calculate: 1£: 1.17€ = 280£: x. Thus, x = 1.17 * 280, giving us x = 327.6 €. Verification shows this calculation is sound.
edf = 54 as well since both angles correspond to each other
Assign x as the hours Carlos drove and y as the hours Maria drove. The first equation is x + y = 4.4, from which we derive x = 4.4 - y. The second equation, representing their distances, is 55x + 50y = 233. Substituting the first equation into the second gives us 55(4.4 - y) + 50y = 233, resulting in a distance traveled of 3.5 m by Carlos in 2.6 hours.
