Answer:
2.1 hours (2 hours and 6 minutes)
Step-by-step explanation:
The rate of work of Bobbi is ⅓ while for Deshaun is 1/7 hence combined rate will be
⅓+1/7=(7+3)/21=10/21
The equivalent hours is the reciprocal of the above hence 1021/10=2.1 hours
0.1 of an hour is equivalent to 0.1*60=6 minutes
Therefore, the efforts combined will take 2.1 hours or 2 hours and 6 minutes
The answer is C) The Distributive property.
2(x+4) got turned into 2x+8.
The distributive property does this:
2 times x plus 2 times 4.
2 times x = 2x
2 times 4 = 8.
So the answer is 2x+8.
C) Distributive property is right.
Answer:
A. 4.2 times
Step-by-step explanation:
Chlorine level of the pool as adjusted by Paula = 6.3 parts per million
Ideal Chlorine level as suggested by the magazine = 1.5 parts per million.
Thus, the number of times the ideal level of Chlorine that the current level is = current level ÷ ideal level
= 
The current Chlorine level is 4.2 times the ideal Chlorine level.
Step 1: Add 3x to both sides.d−3x+3x=−9+3xd=3x−9 = ANSWER
