Verify that (a+b)+c = a+ (b+c) by taking a = -8 , b = (-8/11) , c = (-8/12)

gogolik [260]

Answer:

Step-by-step explanation:

$(-8+-\frac{8}{11} ) + (-\frac{8}{12}) = -\frac{96}{11} + (-\frac{2}{3}) = -\frac{288 + 22}{33}) = -\frac{310}{33}\\ (-8) + (-\frac{8}{11} + (-\frac{2}{3})) = (-8) + (-\frac{46}{33})= -\frac{310}{33}$

A Unites States naval submarine began at sea level. It submerged 140 ft and then traveled 40 miles. It dove down an additional 1

kodGreya [7K]

Answer: -231 ft

Step-by-step explanation:

The submarine started at sea level = 0

It submerged 140 ft = -140 ft

It traveled 40 miles horizontally so it is still at -140 ft

It dove down an additional 120 ft = -260 ft (-140 + -120)

It traveled 25 miles horizontally so it is still at -260 ft

It rose 29 ft = -231 ft (-260 + 29)

Note: submerged and dove are negative values and rose is positive

0 - 140 - 120 + 29 = -231
