Answer:
3
Step-by-step explanation:
Since the shapes are similar this means they are equal.
If the ratio is 2:1 that would mean divide each number by 2.
6/2 reduced equals 3/1 = 3
Commutative property of addition:
a + b = b + a
Associative property of addition:
a + (b + c) = (a + b) + c
Opposite of a sum:
- a - b = - (a + b)
If we look at the options, A and D follow associative property.
B follows commutative property.
C follows opposite of a sum property.

Step-by-step explanation:
Answer: Alejandra gave $60 to the cashier.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given.
We have to subtract to the amount that Alejandra paid(x) the sum of the costs of each product [videogame (24), controller (13) and memory card (169] and the total tax (3). the expression must be equal to the amount received in change.
Mathematically speaking:
x -(24+13+16+3) = 4
Solving for x:
x - 56 =4
x = 4+56
x =60
Alejandra gave $60 to the cashier.
