Mrs. Jones bought 6 kilograms of rice. After filling 10 containers with the same

9966 [12]

There are 514 gram rice in each container.

Step-by-step explanation:

Given,

Amount of rice = 6 kg

1 kg = 1000 g

6 kg = 6*1000 = 6000 g

Number of containers = 10

Rice left = 860 g

Let,

x be the amount in each container.

Total amount of rice - Number of containers*Amount in each container = Amount of rice left

$6000-10x=860\\6000-860=10x\\5140=10x\\10x=5140$

Dividing both sides by 10

$\frac{10x}{10}=\frac{5140}{10}\\x=514$

There are 514 gram rice in each container.

Whats 70-3x6+9 I need the answer plz

kumpel [21]

70-3·6+9

Remember PEMDAS.

You must multiply the 3 and 6 together, and you would get 18.

Then, you subtract 18 from 70, which would give you 52.

And finally, you would add 9 to 52, getting 61 as your final answer.
