3+ 45 + 10n = 48+ 5n ( False)
9- 3(y -2)
= 9 -3y+ 6 =3 -3y (True)
18x -6 -7 = 18x -13(True)
The awnser is going to be -5/7
Yes, by 0.001. Thank me later.
Answer:Move the decimal place to the left to create a new number from 1 up to 10. Where's the decimal point in 312,000,000,000? .
Determine the exponent, which is the number of times you moved the decimal.
Put the number in the correct form for scientific notation.
Step-by-step explanation:
1) (3.8 * 10^3) * (9.4 * 10^-5) = 0.3572 = 3.6 * 10^-1
2) (4.2 * 10^7) * (7.4 * 10^-2) = 3.1 * 10^6
3) (8.6 * 10^-6) * (7.1 * 10^9) / (4.1 * 10^ -2) * ( 2.8 * 10 ^-7) = 5.3 * 10^-6
4) 4.2 * 10^-1
Sorry for not putting my work for number 4. Hope this helps!
