Answer:
2m^4 - 11m³ + m + 8
Step-by-step explanation:
(2m - 5m³) - (5m + 3m³ - 7m^4) + (8 - 3m³ - 5m^4 + 4m)
2m - 5m³ - 5m - 3m³ + 7m^4 + 8 - 3m³ - 5m^4 + 4m
7m^4 - 5m^4 - 5m³ - 3m³ - 3m³ + 2m - 5m + 4m + 8
2m^4 - 11m³ + m + 8
M(Pb(C2H5)4 = M(PB)*1 + 4*( M(C)*2 + M(H)*5)
M(Pb(C2H5)4 = 207.2 + 4(12.0*2 + 1.0*5)
M(Pb(C2H5)4 = 207.2 + 4(28.0 + 5)
M(Pb(C2H5)4 = 207.2 + 4*33
M(Pb(C2H5)4 = 207.2 + 132
M(Pb(C2H5)4 = 339.2 g/mol
Hope this helps !

Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!
For example just flip 3/7 to 7/3
X=6 if you need an explanation commu
Answer:
Tammy's total pay for the week is $588
Step-by-step explanation:
We are given the following in the question:
Tammy's salary = $300 every week
Percentage of commission on sales = 9%
Total sale during week = $3200
Commission earned =
Thus, Tammy's week salary =
Weekly salary + Commission on sales
=
Thus, Tammy's total pay for the week is $588 if she sold $3200 worth of products.
