Solve for x, Show your work: 1/2 (16 - x) = -12 (x + 7)
soldi70 [24.7K]
You have to get rid of 1/2 by multiplying it by its recriprocal which is like this:
1) 1/2 x 2/1 which equals to zero and you do the same to the other side.
2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168.
16-x= -24x -168
3) subtract 16 to the other side and subtract 24x with x
23x= -184
4) divide by 23 to isolate x and you get -8
5) x=-8

Grayson ran 2 1/2 miles around the track .each lap is 5/6 of a mile .how many laps did Grayson run?
andrezito [222]

Given:

Number of miles covered = 2\dfrac{1}{2}

Length of each lap = \dfrac{5}{6} of a mile.

To find:

The number of laps.

Solution:

We know that,

\text{Number of laps}=\dfrac{\text{Number of miles covered}}{\text{Length of each lap}}

\text{Number of laps}=\dfrac{2\dfrac{1}{2}}{\dfrac{5}{6}}

\text{Number of laps}=\dfrac{\dfrac{5}{2}}{\dfrac{5}{6}}

\text{Number of laps}=\dfrac{5}{2}\times \dfrac{6}{5}

\text{Number of laps}=3

Therefore, Grayson ran 3 laps.

Find the particular solution of the differential equation dy + 7y = 6 satisfying the initial condition y(0) = 0. Answer: y= Your
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

We have the equation y'+7y=6 with the initial condition y(0)=0. It is not difficult to notice that this is a linear equation, which has the general expression

y'+P(x)y=Q(x).

The solution of this equation is expressed by a general formula:

y(x) = \exp\left(-\int P(x)dx\right)\left(\int Q(x)\exp\left(-\int P(x)dx\right) +C\right).

In the particular case of our equation, we have

P(x)=7

Q(x)=6.

Then, we must calculate the integrals

\int 7dx = 7x that implies

\exp\left(-\int P(x)dx\right) = e^{-7x},

and

\int 6e^{7x}dx = \frac{6}{7}e^{7x}

Then,

y(x) = e^{-7x}\left(\frac{6}{7}e^{7x} +C\right) = \frac{6}{7} + Ce^{-7x}.

In order to obtain the value of the constant we substitute the initial condition

0=y(0) = \frac{6}{7} + C that implies C=-\frac{6}{7}

Therefore,

y(x) = \frac{6}{7}-\frac{6}{7}e^{-7x}.
