$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
312&100\\
55&p
\end{array}\implies \cfrac{312}{55}=\cfrac{100}{p}\implies p=\cfrac{55\cdot 100}{312}$

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
