Hitman42 [59]

Answer:

a=3, c=-4, x=8

Step-by-step explanation:

5=4a-7

4a-7=5

4a=5+7

How is 10,021 divisible by 11
tangare [24]

Answer:

See below

Step-by-step explanation:

1-0+0-2+1=0, so since 0/11=0, it's divisible by 11

The rule for divisibility by 11 is that you subtract then add then subtract then add and so on, and if you get a number divisible by 11 or equal to 0, then it's divisible by 11.

Hope that made sense.
