melisa1 [442]

Answer:

a = -3/2

Step-by-step explanation:

3(6a+12)=9

denis-greek [22]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Total watches in an inventory = 1000

Number of shipments sent out = 168, 231, 411

So, Remaining inventory of watches would be :

1000-(168+231+411)\\\\=1000-810\\\\=190

New receipts = 21, 145 and 11

So, Number of watches on hand becomes :

190+(21+145+11)\\\\=367

Hence, Third option is correct.

Is 4/5 equal to 5/10?
vfiekz [6]
No, 4/5 does not equal to 5/10.

Because:- When you try to see if it is proportional, it does not equal it.

4/5 ≠ 5/10

Simplify to make sure.

4/5 ≠ 1/2

4/5 is NOT equal to 1/2.

Therefore, our final answer is that 4/5 does not equal 5/10.
