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]
Convert 2 3/8 into 6/8
6/8 * 1/3 = 6/24
<span>So that the ratio is defined:
* The </span><span><span>denominator</span> can not be zero
* Being an integer index pair, the filing must be greater or equal to zero.
It is concluded that:</span>
x ≠ 0 ∧ 2x ≥ 0

10/7
Because root of 100 is 10, root of 49 is 7
Answer:
Step-by-step explanation:
solution 1 :
adult : 7 - x
child : x
total spend : 54.50 = (7 - x) * 9.5 + x * 6.5
we solve : 54.50 = 66.5 - 3x , x = 4
solution 1 :
adult : y
child : x
x + y = 7.......(1)
total spend : 54.50 = y * 9.5 + x * 6.5........(2)
we solve : x= 4 , y = 3
