Alex's dog weighs 7 times as much as her cat. Together, the two pets weigh 72 pounds. How much does Alex's dog weigh?
raketka [301]
D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb

An expression to convert 50 miles per hour to miles per minute is shown.
Nataliya [291]
Use the fact that 1 hour = 60 minutes, from which you can create your conversion factor: 1 = hour / 60 minutes. That permit you to multiply the number of miles per hour times [1 hour/60minutes] to convert 50 miles per hours to miles per minute. This is the calculation: 50 miles/hour * [1hour/60minures] = 0.833 miles / minute
