Answer:
1 is 9 sq units
2 is 12
3 is 24cm^2
Step-by-step explanation:
3x + 1 + 5x = 7 + 15 + 7x
8x + 1 = 22 + 7x
x = 21
Write and solve an equation of ratios, as follows:
32 fl oz 60 min
----------- = ------------
x 135 min
Then 60x = (32)(135) = 4320, and x = 72 oz.
damron should drink 72 fl. oz. of water if he rides 135 min.
