Both sides were multiplied by 3 to get Step 1, so the property is the Multiplication Property of Equality. Choice D.

Lol hopefully I helped !!
10000 different phone numbers are possible for a particular prefix if repetion of digits is allowed
5040 different phone numbers are possible for a particular prefix if repetion of digits is not allowed
<em><u>Solution:</u></em>
Given that,
A seven digit phone number consists of a three-digit prefix followed by four digits
We have to find the different phone numbers are possible for a particular prefix
For a paricualr prefix, there are four digits
Total numbers from 0 to 9 are 10
Therefore,
Different ways for phone number for particular prefix:
If repetition is allowed:
Different ways = 10 x 10 x 10 x 10 = 10000 ways
If repetition is not allowed then:
Different ways = 10 x 9 x 8 x 7 = 5040 ways
Answer: A -11
Step-by-step explanation:
its quite simple
subract 9(-) from negative 2
Answer: 20 6-cents, 30 8-cents, 10 10-cents and 2 20- cents
Step-by-step explanation:
6 cent = x+10
10 cent= x
8 cent= 3x
20 cent=2
6x+60+10x+24x+40
400 divided by 40=X
x=10.
10+10=20/ 6 cents
3x10=30/ 8 cents
x=10/ 10 cents
20 cents= 2.
