15 litres per minute times three minutes is 45 litres for three minutes, and half a minute's worth of water in the shower is 7 1/2 (half of 15). 45+7 1/2= 52 1/2 litres of water.<span>The difference between 100 and 52 1/2 is 47 1/2, which is our final answer.</span>

Given the vectors, a=3i+4j, b=-2i+5j, c=10i-j, d=-1/3i + 5/2j, find a+(b-c)=?
Tomtit [17]

Answer:

  a +(b -c) = -9i +10j

Step-by-step explanation:

You can use the distributive property to remove the parentheses:

  a +(b -c) = a + b - c

Add the vectors as though they were binomials.

  a + b - c = (3 -2 -10)i +(4 +5 -(-1))j = -9i +10j
