X-3y=18
X always has a 1 in front of it so
1x-3y=18
-1x -1x You will have to get -3y by its self.
-3y=-1x + 18 when you move 1x over the = it turns into a -1x
/-3 /-3 /-3 divided everything by -3 to get y by its self
Y= 1/3 - 6 and that is you answer

Step-by-step explanation:

x-3y=18 were going to put the x's on one side and the y's one side

-3y=18-x so to get y by itself where going to have to divide -3y by -3 but remember what ever you do to one side u do to the other

-3y/-3 = 18/-3-x/-3 - with a - is +

y= -6 + 1x/3

A miniature quadcopter is located at xi = −1.75 m and yi = −5.70 m at t = 0 and moves with an average velocity having components

Black_prince [1.1K]

The quadcopter's average velocity is given in terms of change in position by

$\vec v_{\rm av}=\dfrac{\Delta x}{\Delta t}\,\vec\imath+\dfrac{\Delta y}{\Delta t}\,\vec\jmath$

where $\Delta x=x_f-x_i$ , the difference in the quadcopter's final and initial positions and $\Delta t=(1.60-0)\,\mathrm s=1.60\,\mathrm s$ .

The $x$ -component of the average velocity is 2.70 m/s, so

$2.70\dfrac{\rm m}{\rm s}=\dfrac{x_f-(-1.75\,\mathrm m)}{1.60\,\rm s}\implies \boxed{x_f=2.57\,\mathrm m}$

and the $y$ -component is -2.50 m/s, so

$-2.50\dfrac{\rm m}{\rm s}=\dfrac{y_f-(-5.70\,\mathrm m)}{1.60\,\rm s}\implies\boxed{y_f=-9.70\,\mathrm m}$

Marcellus sent four faxes to Gem. The first fax took 14 seconds to send, the second fax 19 seconds, the third 16 seconds, and th

Scrat [10]

It took 60 seconds to fax all documents to Gem

Step-by-step explanation:

The simple addition has to be done to solve the given problem

Given

total faxes = 4

Time for fax 1: $t_1 = 14\ sec$

Time for fax 2: $t_2 = 19\ sec$

Time for fax 3: $t_3 = 16\ sec$

Time for fax 4: $t_4 = 11\ sec$

The total time t will be:

$t = t_1+t_2+t_3+t_4\\= 14+19+16+11\\= 60\ sec$

Hence,

It took 60 seconds to fax all documents to Gem

see explanation below

(1) $\frac{1}{5}$ × $\frac{2}{2}$ = $\frac{2}{10}$ = 0.2

(2) $\frac{6}{25}$ × $\frac{4}{4}$ = $\frac{24}{100}$ = 0.24

(3) 2 $\frac{3}{4}$ = 2 + $\frac{75}{100}$ = 2.75

(4) 3 $\frac{9}{10}$ = 3 + 0.9 = 3.9

(5) 1.25 = 1 $\frac{1}{4}$ = $\frac{5}{4}$

(6) 3.29 = 3 $\frac{29}{100}$ = $\frac{329}{100}$

(7) 0.65 = $\frac{65}{100}$ = $\frac{13}{20}$ in simplest form

(8) 5.6 = 5 $\frac{6}{10}$ = 5 $\frac{3}{5}$ = $\frac{28}{5}$

(9) he is incorrect

$\frac{3}{5}$ × $\frac{20}{20}$ = $\frac{60}{100}$ = 0.6 ≠ 3.5

1. Find the probability of this set of independent events. rolling a six on the first roll of a 1-6 number cube and rolling an o

jeyben [28]

For the first question, the chance of rolling a six is a 1/6 chance because there is one six and six different sides that could be rolled. As a percent, it would be 16.6 %. The probability of rolling an odd number on the second roll would be a 3/6 chance, which as a percent is 50 %. For the second question, both probabilities are 33 % because in both instances you are drawing three cards from nine total, so it would be 3/9. For the third question, the probability of drawing a blue marble is 3/5, because there are three blue marbles and five total marbles. As a percent, this is 60 %. Following this up with a green marble would be 2/4, because there are now 2 green marbles and four total marbles. One of the marbles was not replaced, so we have one less marble. 2/4 as a percent is 50%.

Last year, Edward spent a total of $626.14 on his power bill. Rounding the total bill to the nearest tens place, approximate how

zlopas [31]

Answer:

He spent around $ 52.17 in each month.

Step-by-step explanation:

Last year the power bill price = $ 626.14 ≈ $ 626

We know that in a year 12 months. so power bill of each month in last year is calculated as follows

$Power \ bill \ of \ each \ month = \frac{Total \ bill \ of \ the \ year}{12}$
