Answer:
6 13/20 hours
Step-by-step explanation:
Addition of fractions requires they be expressed using a common denominator. Here, that will be 5·4 = 20, and the two fractions can be written as ...
2/5 = 8/20
1/4 = 5/20
Then the sum of the mixed numbers is ...
(4 2/5) +(2 1/4) = (4 +2) +(2/5 +1/4) = 6 +(8/20 +5/20)
= 6 13/20
It took Kareem 6 13/20 hours to clean the two rooms.
Yes because you multiply first so in this case you multiply 7 and 3 first. Since the second expression is in parenthesis you do that first just like you do 7 times 3. Then you just add 2 to that. The value of both expressions is 23
Supplementary angles add up to 180°.
So (180-X) would be the equation to use to find an angles supplement.

Answer:
second option
Step-by-step explanation:
Given
f(x) = 
The denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be, that is
3x - 5 = 0 ⇒ 3x = 5 ⇒ x =
← excluded value
Thus domain is
(- ∞,
) u (
, ∞ )
