So say we have the number: 54,321

The 5 would be worth 50,000 meaning it's in the ten thousands place.

The 4 would be worth 4,000 meaning it's in the thousands place.

.

The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place

.

Hope that helps :)

Which expression is equivalent to 7c +4 + 10c – 6?<br> 15<br> 15c<br> 17c - 2
slega [8]

Answer:

17c - 2

Step-by-step explanation:

Firstly, add the normal numbers together:

7c + 4 + 10c - 6

4 - 6 = -2

7c + 10c - 2

Now, the two numbers with a c value can be added together:

7c + 10c = 17c

This returns the answer:

17c - 2

Hope this helps!
