Answer:
$1429.64
Step-by-step explanation:
1109.52 + 706.34 = 1815.86
1815.86 + 18.10 = 1833.96
1833.96 - 29.24 = 1804.72
1804.72 - 375.08 = 1429.64
Therefore by the end of the week, Alex's account balance will be $1429.64 by the end of the week.
Answer:
110 - 2x
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 50 + 5x - 40 + 110 - 2x = 180, that is
4x + 120 = 180 ( subtract 120 from both sides )
4x = 60 ( divide both sides by 4 )
x = 15
Thus
x + 50 = 15 + 50 = 65°
5x - 40 = 5(15) - 40 = 75 - 40 = 35°
110 - 2x = 110 - 2(15) = 110 - 30 = 80°
The largest angle is (110 - 2x)° = 80°

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.
