Answer:a=-7

Step-by-step explanation:The given equation is 3(a-7)=6a

Using distributive rule we have:

3a-21=6a

21 is subtracted to 3a .We always perform the opposite operation both sides.

Opposite of subtraction is addition

Adding 21 both sides

3a=6a+21

Subtracting 6a both sides:

3a-6a=21

-3a=21

Dividing both sides by -3 we have

a=-7.

A restaurant has 4 appetizers, 5 entrees and 2 desserts. How many different meal combinations could you order?

vovangra [49]

Step-by-step explanation:

1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things

2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!

3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!
