Answer:
160
Step-by-step explanation:
is there 240 seventh graders in total? If so all you have to do is:

which equals 160 seventh graders.
Answer: (C) It can be shown that W = x y z ∈ R 3 : x + 2y − 4z = 0 and y − 3z = 0 is a subspace of the vector space R 3 , and the dimension of W is 2.
Step-by-step explanation:
Answer:
0.3
Step-by-step explanation:
you would add -2/4 to both sides and subtract x from both sides to get 5x=1.5 which you can reduce to 0.3
Answer:
\bf xy=1\iff y = \cfrac{1}{x}\iff y = x^{-1}\\\\ -----------------------------\\\\ \cfrac{dy}{dt}=-x^{-2}\cdot \cfrac{dx}{dt}\impliedby \textit{using the chain-rule} \\\\\\ \left. \cfrac{dy}{dt}=-\cfrac{\frac{dx}{dt}}{x^2} \right|{ \begin{array}{llll} x=2\\ \frac{dx}{dt}=-2 \end{array}}\implies \cfrac{dy}{dt}=-\cfrac{-2}{2^2}
Step-by-step explanation:
