Which is the expanded form of 124,750,000?
a. 124,000 + 750,000
b. 100,000,000 + 20,000,000 + 4,000,000 + 700,000 + 50,000
c. 124,000 + 750
d. 124 x 1000 + 75 x 1000

B.

Step-by-step explanation: When we talk about expanded form we are talking expanded right?

So, you wouldn't want to combine the 100,000,000 and the 20,000,000 and the 4,000,000 you want them expanded out just like I had them, so A is out.

Next we have C. We are talking about thousands here so the 750 doesn't make sense.

Finally, we have D. with expanded form we only want addition no multiplication so for that reason D. is out

B. Looks good to me they expanded everything out no multiplication, no numbers combined (eg. 124,000) so for that reason B. is the answer!

If you need any further instruction or help let me know!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
