5/6 of an hour is 50 minutes. 2/5 of an hour is 24 minutes (1/5 of 60 is 12 times 2 is 24) 50 minus 24 is 26. There are 26 minutes left in the class.

Help help help guys show you solution​
Mars2501 [29]

Answer:

Step-by-step explanation:

1) y  = 2x  ----------(I)

x + y = 6 -----------(II)

Plug in y =2x in equation (II)

x + 2x = 6        {Add like terms}

  3x    = 6

       x = 6/3

      x = 2

Plugin x = 2 in (I)

 y = 2*2

y = 4

<u>Check: </u>

     LHS = x +y

             = 2 + 4

            = 6  = RHS

2)5x + 10y = 3 ------------(I)

x = (-1/2) y     ------------(II)

Substitute x = (-1/2)y in (I)

5*\frac{-1}{2}y + 10y = 3\\\\\frac{-5}{2}y+ \frac{10*2}{1*2}y = 3\\\\\frac{-5}{2}y+\frac{20}{2}y=3\\\\\frac{-5+20}{2}y = 3\\\\\frac{15}{2}y=3\\\\    y = 3*\frac{2}{15}\\\\   y = \frac{2}{5}

Substitute y = (2/5) in equation (II)

x = \frac{-1}{2}*\frac{2}{5}\\\\x = \frac{-1}{5}

<u>Check:</u>

Substitute x and y value in equation (I)

LHS = 5*\frac{-1}{5}+10*\frac{2}{5}\\\\  = -1 + 2*2\\\\ = -1 + 4\\ = 3 = RHS

3) y - x = 3x + 2

        y = 3x + 2 + x

         y = 4x + 2 ---------------(I)

2x + 2y = 14 - y

2x + 2y +y = 14

2x + 3y = 14     ------------------(II)

Substitute y = 4x + 2 in equation (II)

2x + 3(4x +2) = 14

2x + 3*4x + 3*2 = 14

2x + 12x + 6 = 14

        14x + 6 = 14

              14x = 14 - 6

              14x = 8

                 x = 8/14

            x = 4/7

Substitute 'x' value in (I)

y = 4*\frac{4}{7} +2\\\\y = \frac{16}{7}+2\\\\y= \frac{16}{7}+\frac{2*7}{1*7}\\\\y=\frac{16}{7}+\frac{14}{7}\\\\y=\frac{30}{7}

<u>Check:</u>

<u />LHS = 2x + 3y\\\\      = 2*\frac{4}{7}+3*\frac{30}{7}\\\\  = \frac{8}{7}+\frac{90}{7}\\\\=\frac{8+90}{7}\\\\=\frac{98}{7}\\\\=14 = RHS<u />

Find the arc length of the partial circle..
Gala2k [10]

Answer:

The arc length of the partial circle is 6\pi\ units

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

In this problem we have a 3/4 of a circle

so

the circumference is equal to

C=(\frac{3}{4})2\pi r

C=\frac{3}{2}\pi r

we have

r=4\ units

substitute

C=\frac{3}{2}\pi (4)

C=6\pi\ units
