3/5n 9/10=1/5n-23/10

Mathematics
1 answer:
castortr0y [4]4 years ago
5 0

(3/5n)(9)10=1/5n−23/10

27/50n=1/5n+−23/10

Subtract 1/5n from both sides.

27/50n−1/5n=1/5n+−23/10−1/5n

17/50n=−23/10

Multiply both sides by 50/17.

(50/17)*(17/50n)=(50/17)*(−23/10)

n=−115/17

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or li
AlladinOne [14]

The set is linearly dependent.

To explicitly prove this, we need to show there is at least one choice of constants c_1,c_2,c_3,c_3\in\Bbb R such that

c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0

or equivalently,

(c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0

which is the same as solving the system of equations

\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}

From the first and last equations, we have c_1=-c_4 and c_3=c_4. Substituting these into the second equation leaves us with c_2-2c_1=0, and so the overall solution set is

c_1 = \dfrac12 c_2 = -c_3 = -c_4

for which there are infinitely many not-all-zero solutions.

A slice of carrot cake from The Cheesecake Factory contains 1,560 calories. This represents 75% of the average daily calorie req
Dennis_Churaev [7]

Answer:

Step 1 of 5

(1). Familiarize.

<em>The energy in the slice of carrot cake is described in terms of the requirement of energy of an adult on a day. </em>

<em> </em>

<em>So we let x calories = the requirement of energy of an adult on a day.</em>

<em>3/4 ( x ) calories </em>

<em> </em>

<em>Then  is the energy in the slice of carrot cake. </em>

<em> </em>

<em>The energy in the slice of carrot cake is 1560 calories.</em>
