Answer:

<u>17-(- 2 / 5j)</u>

Step-by-step explanation:

16 + (- 5 ) - 2/5j - 4/5 j + 6

    \/                  \/            \/

    11-         ( -2/5j )       + 6

From here you over  the 6 over to the 11

11+6-(-2/5j)

 \/

17-(-2/5j)

It can not be simplified farther I believe

One lap around the school track is 5/8 of a mile Carin ran 3 1/2 laps how far did she run
bearhunter [10]

Given length of a lap = 5/8 mile.

Number of laps Carin ran = 3 1/2 laps.

3 1/2 can be read as 3 and a half. In improper fractions, it can be written as

(3*2+1)/2 = 7/2 laps.

In order to find the total distance covered in 3 1/2 or 7/2 laps, we need to multiply length of a lap by total number of laps ran.

Therefore, total distance covered = 7/2 × 5/8.

=\frac{7}{2}\times\frac{5}{8}

Multiplying across, we get

= \frac{7\times5}{2\times8}

=\frac{35}{16}

Let us convert 35/16 into mixed fractions.

On dividing 35 by 16, we get 2 quotient and 3 remainder.

So, the mixed fraction would be 2 3/16.

Therefore, she ran 2 3/16 miles in 3 1/2 laps.

Write equations for the horizontal and vertical lines passing through the point (-6,1)
Oksanka [162]

Answer:

y = 1 and x = - 6

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c ( where c is the value of the y- coordinates the line passes through )

The line passes through (- 6, 1 ) with y- coordinate 1 , then

y = 1 ← equation of horizontal line

The equation of a vertical line parallel to the y- axis is

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, 1 ) with x- coordinate - 6 , then

x = - 6  ← is equation of vertical line
