Answer:
3.940201X 10^115
Step-by-step explanation:
2^3x (2x2x2x2x2x2x2)
2^3x128
2^384
3.940201 x 10^115
The longest bolt is 1 4/8 inches, and the shortest bolt is 3/8 inch.
Subtract 3/8 from 1 4/8 to get 1 1/8 inch difference.
Answer:-8
Step-by-step explanation:
8+4a=3a
8=3a-4a
8=-a
a=-8
Guppies: u
Goldfish: o
3 times as many guppies as goldfish
3*o = u (there are more guppies than goldfish)
o + u = 20
o = 20 - u
Substitute in (20 - u) for o in the first equation and solve:
3* (20 - u) = u
60 - 3u = u
60 = 4u
u = 15
He has 15 guppies. Then substitute in the number of guppies into either equation to find the number of goldfish:
o + u = 20
o + (15) = 20
o = 5
Hope this helps! :)
