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.
