1.) 6x-8y=18, 2x+8y=6 → Multiplication property of equality
2.) 8x=24 → Addition property of equality
3.) x=3 → Division property of equality
4.) 3(3)-4y=9 → Substitution property of equality
5.) 9-4y=9 → Simplify
6.) -4y=0 → Subtraction property of equality
7.) y=0 → Division property of equality
The reasonable estimate of 288 can be 300 because it's close to 300
Answer:
-35.25 - 8.5 = -40.75 meters
Step-by-step explanation:
When talking about a submersion depth of -32.25 meters, that means the submarine has dropped 32.25 meters.
If we add 8.5 meters of additional submersion to that value, we get:
-32.25 meters + (-8.5 meters) = -32.25 meters - 8.5 meters = -40.75 meters.
Answer:
The simplest form of 2790 is 310.
