Answer:
Always
Step-by-step explanation:
8 - 9 = -1
1/3 - 1/6 = 1/6 are 2 examples
The maximum height is 64ft and the ballon is only in the air for 2 seconds
10t = b - 4
12b+8t = $348
This is a system of equations. I’ll be solving through substitution.
In the first equation. solving for b (the easier variable to isolate) gives you:
b = 10t + 4
Substitute this into the second equation:
12(10t+4) +8t = 348
120t+48+8t = 348
128t = 300
t = 2.34375 —> round it to the nearest cent to get 2.34 dollars
b = 10t+4
b = 10(2.34)+4
b = 27.4 dollars
Giraffe = 1,000 kg
Whale = 2,000,000 kg
Whale has 2,000 times the mass.
