42
let the smallest even number be x, than the four even numbers are x, x+2, x+4, x+6, their sum is 180
x+x+2+x+4+x+6=180
4x+12=180
4x=168
x=42
the smallest even number is 42.
a) 75 percent of the regular price is the price for senior citizens.
b) $6.712 is the price for senior citizens.
<u>Step-by-step explanation</u>:
- The regular price is the 100% = $8.95
- The offer price for senior citizen = 15% discount from 100%
∴ Percent of the regular price for senior citizens = 100% - 15% = 75%
The price for the senior citizens = 75% of $8.95
⇒ (75/100)
8.95
⇒ 0.758.95
⇒ 6.712 dollars.
∴ The price for senior citizens = $6.712
Answer:
1/4
Step-by-step explanation:
total balls=7+4+4+5=20
probability of green marble=?
green marbles are 5 so,
Probability=number of favourable outcomes / number of all possible outcomes
total outcomes=20
green ball chances=5
=5/20
=1/4
I might want to use the commutative property to change the order of the integers in the following sum before adding the given expression
"-80 + (-173)+(-20)"
As commutative property states that " Changing the order of addends does not change the sum" which means if we add 'a' to 'b' or 'b' to 'a', we will get the same answer.
Therefore, here if we add '-80' to '-173' or '-173' to '-80' , or if we add '-173' to '-20' or '-20' to '-173' , we will get the same answer.
Therefore, we might use commutative property to change the order the of integers in the following sum.
