Answer: The answer is 1320 hope this is right.
Step-by-step explanation:
Katy spends 8/10. 1/10 and 1/5=2/10 and 1/2=5/10 so 1/10+2/10+5/10=8/10 or 4/5 simplified.
Answer:
9
Step-by-step explanation:
if you substitute a for 3 and b for 2 you should get 9
Replace each of the x values given to see if they give 0.
0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259
0=(1)³+(1)²-1
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.
