6 x 1 = 6 /2 =3. For 6*1/2
3/5 x 1/4 = 3*1/5*4 = 3/20
Answer:
Multiply By Decimal
Step-by-step explanation:
If you multiply a number by a decimal you get the same outcome that you would if you would have divided it
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

Answer:
x - 5 = x - 2 and
x - 5 = 2 - x.
Step-by-step explanation:
x - 5 may be positive or negative so we have:
x - 5 = x - 2
and
x - 5 = - (x - 2)
x - 5 = 2 - x.
Answer:
8 hours.
Step-by-step explanation:
The pizza house will pay 10 - 6 = 4 dollars in late charges. Each hour costs them 1 dollar. (0.25 per 1/2 hour 0.50 dollars for 1 hour.)
So 1 hour gives a reduction of 0.50 dollars.
x hours gives a reduction of 4 dollars.
0.50 x = 4.00 dollars.
x = 4/0.50
x = 8 hours.
If they keep that up, they will be out of business before too long.
