Question

@Mathemathics what is the equivalent of 3 quarts per second in gallons per hour?

sovle -9_< -2x +3_<1
a. 3_> x_> -1
b.6_x_>1

Answer 1

3 qt/ sec to gal/hour
to get seconds to hours you multiply by 3600sec/hour
to go from qt to gal multiply by 1gal/4qts
(3 qt/sec) * (3600sec/hour) * (1gal/4qts) = 2700 gal/hour

Answer 2

what about sovle -9_< -2x +3_<1
a. 3_> x_> -1
b.6_<x_< 1
c.3_<x_<-1
d. 6_>x_>1

Answer 3

-9 ≤ -2x +3 ≤ 1
subtract 3 from everything:
-12 ≤ -2x ≤ -2
divide by -2 (and flip signs)
6 ≥ x ≥ 1
so I would say d

thanks so much
