The answer is really 1 5/6 because 5/6 + 2/3=5/6 NOT 7/3 so of course she is wrong
40,000 = 4 * 10^4
0.000004 = 4 * 10^-6
The power of 10 exactly in between 4 and -6 is -1.
She started with 4 * 10^(-1) which is 0.4.
0.4 * 100,000 = 40,000
0.4/100,000 = 0.000004
The number she started with is 0.4.
The power is 10^5.
Answer:
Step-by-step explanation:
<u>Solve for x:</u>
- 1/2 (4x - 8) + 3x = 36
- 2x - 4 + 3x = 36
- 5x - 4 = 36
- 5x = 40
- x = 40/5
- x = 8
Answer: A+C=500
7.5A+4.75C=3351.25
C=500-A
7.5A+4.75(500-A)=3351.25
7.5A+2375-4.75A=3351.25
2.75A=976.25
A=355 adults ($2662.50)
C=500-A=145 children ($688.75)
