Answer:
z
Step-by-step explanation:
the y' should be 5 then 10 .20.40.80 since it double every day
Answer:
25x + 5y + z cents
Step-by-step explanation:
1 quarter is worth 25 cents.
1 nickel is worth 5 cents.
1 penny is worth 1 cent.
Therefore, x quarters, y nickels and x pennies will be worth:
(x * 25) + (y * 5) + (z * 1)
= 25x + 5y + z cents
The correct answer is: Commutative Property
Further Explanation:
The commutative property states that the order of number doesn't matter and changing the order of numbers or variables will produce the same result.
<u>Commutative Property of Addition:</u>

Answer:
The correct option (c) "is held together by ionic bonds".
Step-by-step explanation:
Table salt is NaCl. It is a combination of Sodium and Chlorine.
There is 1 valance electron in sodium. Its electronic configuration is 2,8,1
The electronic configuration of Chlorine is 2,8,7. It means that it needs 1 electron so that its octet gets completed.
Na transfers one electron to Cl. It becomes Na⁺. Cl gains one electron From Na. It becomes Cl⁻.
As a resuslt, Na⁺ and Cl⁻ forms. Both Na and Cl are ions. They held together by ionic bonds.
