Marco can paddle his canoe at a rate of 6 miles per hour on unmoving water. However, today
Marco is canoeing down (with the current), and
then back up (against the current), a river that's
moving at a rate of 1 mile per hour, so the
current affects his rate of speed. If it takes Marco
6 total hours to go x miles downstream and then
return to his starting point, how far downstream
does he travel?
A) 1.25 miles
B) 2.5 miles
C) 5 miles
D) 17.5 miles

The angles below are supplementary. what is the value of x? a pair of supplementary angles is shown. one angle measures 7x + 33, and the other angle measures 70. 5.3 8.14 11 14.7

Ineed with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x

In may you used 400 kilowatt-hours of energy for electricity. a. calculate the total electrical energy use in joules. b. calculate your average power use in watts. c. assume that your power supplier generates electricity by burning oil. note that 1 liter of oil releases 12 million joules of energy. how much oil is needed to generate the electricity you use? give your answer in both liters and gallons. a. the total electrical energy use was nothing _ joules. (type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)
