9r because 4+9 is 13+7 is 20-11 is 9
Answer:
93 miles
Step-by-step explanation:
Use the distance formula:
d =
Plug in the values:
d =
d =
d =
d = 93.4
= 93 miles
The answer is d 8x^2 - 10
Answer:
-60 3/4m
Step-by-step explanation:
The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.
-50-10=-60
-(1/4)-(1/2)= (1/4)+(1/2)
(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.
=6/8 (simplifies down to 3/4)
