2+d=2-3(d-5)-2 Pls show work

defon

2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: $d = -3(d - 5) - 2$
Second, expand. / Your problem should look like: $d = -3d + 15 - 2$
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: $d = -3d + 13$
Fourth, add 3d to both sides. / Your problem should look like: $d + 3d = 13$
Fifth, add d + 3d to get 4d. / Your problem should look like: $4d = 13$
Sixth, divide both sides by 4. / Your problem should look like: $d = \frac{13}{4}$

Answer as fraction: $d = \frac{13}{4}$
Answer as decimal: $d = 3.25$

For the data in the table, write an equation for the direct variation.

melisa1 [442]

The equation of direct variation is,

$\begin{gathered} y=kx \\ k=\frac{y}{x} \end{gathered}$

Substitute the values of y and x.

$\begin{gathered} k=\frac{5.4}{4} \\ k=1.35 \end{gathered}$

So, the obtained equation will be y=1.35(x).

Let's check with the values of x.

1) If x=4

$\begin{gathered} y=1.35x \\ y=1.35(4) \\ y=5.4 \end{gathered}$

2) If x=2

$\begin{gathered} y=1.35x \\ y=1.35(2) \\ y=2.7 \end{gathered}$

3) If x=-2

You know that the battery in your alarm clock is going to run out of power soon. If it runs out within the next 24 hours, what i

aivan3 [116]

The probability of an event is given by the number of favorable outcomes divided by the total number of outcomes. Here the event is the alarm clock running out of power. There are 24 hours during which the power can go out. You are asleep during 8 of these. A "favorable" outcome in this case is the power going out while you are sleeping -- that is, during one of those 8 hours. This makes the probability that the power goes out while you are sleeping 8/24.
