**Answer:**

**Step-by-step explanation:**

Distributive Law:The distributive Property says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

a×(b+c)= a×b+a×c

commutative property: Commutative property says that we can swap numbers over and still get the same answer.

p×q=q×p

∴d( 10+20)

=d×10+d×20 [using distributive property]

=d×10+20×d [ using commutative property]

54/(2X3)=54 divided by 6, =9 square root of 9 is 3

1. 3 times a number less than the sum of twice a number and 2.

Let x be the number

The sum of twice of x and 2 is 2x + 2.

3 times a number less than this is 2x + 2 - 3x = -x + 2.

2. 6 multiplied by the sum of a number and 8.

Let x be the number

The sum of a number and 8 is x + 8.

6 multiplied by this is 6(x+8) = 6x + 48

3. Jane saves $10 per week, so after w weeks, she saves 10w.

She already has $50, so she then has 50 + 10w.
