Answer:
Efficiency (Work done per day) for :
( ˘ ³˘)/
A & B together = 1/35th
A alone = 1/60th
Thus, efficiency of B alone = Total - A’s efficiency
Step-by-step explanation:
OR Efficiency of B alone = (1/35) - (1/60) = 6/210 - 3.5/210 = 2.5/210 = 1/84th
Hence, since B completes 1/84th work daily, he would take 84 days to complete the work alone.
Linear is basically a straight line on a graph and in a table when why changes it choice change the same amount through out for example 3,6,9,12,15 it’s by three if it’s like 2.1.3.3 it wouldn’t be linear bcuz it goes -1,+2,0
Communitive property of addiction
Answer:
7.35 miles per hour
Step-by-step explanation:
Divide 29.4 by 4
2x + y = 3
6x = 9 - 3y
↓
2x + y = 3
6x + 3y = 9
3(2x + y = 3)
3(2x) + 3(y) = 3(3)
6x + 3y = 9
There is an infinite number of solutions in the system (the answer is C).
