Each term has a common divisor of 
:
133 = 7*19, so the number in the blanks is .
The answer would be A.132 because when you add the corner length to 90 it equals 132
Sue = 2 Sally
Sara = Sue - 1
= (2Sally) - 1
Sally + Sue + Sara = 49
Sally + 2 Sally + 2 Sally - 1 = 49
5 Sally = 49 + 1
5 Sally = 50
Sally = 10
Sue = 20
Sara = 19
Answer:
C.
Step-by-step explanation:
First, we calculate the amount if ammonia in 22 gallons of 16% ammonia solution.
16% * 22 gal = 3.52 gal
The amount of ammonia remains the same after the water evaporates, but the total amount of solution is reduced by the amount of water that evaporates.
amount of ammonia: 3.52 gal
amount of water that remains: 22 - n
desired concentration, 24% = 24/100
Equation:
(3.52)/(22 - n) = 24/100
Answer: C.
