Answer:

  both equations reduce to y = -1/3x -2

Step-by-step explanation:

In each case, subtract the term not containing y and divide by the coefficient of y.

1.  6y = -2x -12 . . . . 12 was subtracted from both sides

  y = -1/3x -2 . . . . . . the equation was divided by 6

__

2. 3y = -x -6 . . . . . . x was subtracted from both sides

  y = -1/3x -2 . . . . . the equation was divided by 3

Eduardo’s average speed on his commute to work was 55 miles per hour. On the way home, he hit traffic and only averaged 40 miles
alekssr [168]

Answer:

40(1.25-t)

Step-by-step explanation:

There are 3 components to consider; time, speed and distance

Time and Speed are given.

The distance has to be calculated.

  • Speed to work = 55 miles per hour
  • Time to work = 1.25-T
  • Speed to home = 40 miles per hour
  • Time to home = 1.25-t
  • Total Time = T + t = 1.25

<u>Distance for trip to home</u>

Speed = Distance/Time

40 = Total Distance/1.25-t

Total Distance = 40(1.25-t)

<em>Therefore, 40(1.25-t) is the correct answer.</em>

X÷0.4=2 1/9 ÷3 1/6 solve for x
Diano4ka-milaya [45]

Answer:

x = 0.27

Step-by-step explanation:

Given:

x÷0.4=2 1/9 ÷3 1/6

To Find:

x = ?

Solution:

First we will see what is

2\frac{1}{9}= \frac{2\times 9 + 1}{9} \\\\2\frac{1}{9}= \frac{18 + 1}{9} \\\\2\frac{1}{9}= \frac{19}{9} \\\\Similarly,\\\\3\frac{1}{6}= \frac{3\times 6 + 1}{6} \\\\3\frac{1}{6}= \frac{18 + 1}{6} \\\\3\frac{1}{6}= \frac{19}{6} \\

Now the final equation is

\frac{x}{0.4} =\frac{\frac{19}{9}}{\frac{19}{6}}\\\\\frac{x}{0.4} =\frac{6}{9}\\\\\frac{x}{0.4} =\frac{2}{3}\\\\\therefore x = 0.4\times \frac{2}{3}\\\\x = \frac{0.8}{3}\\\\x=0.2666\\\\x=0.27

x = 0.27
