Answer:

Step-by-step explanation:

Required man days to complete the job = 8 * 6

                                                                   = 48 Man Days

Required labors to complete the job by 15 days = 48/15

                                                                               = 3.2

It means, it is required 4 labors can complete the certain work by 15 days

The orgin of the coordinate plane is the point at (0,0). Why is the orgin an important point?
stiks02 [169]

<u>Importance of origin:</u>

The point at which the two axes intersect is called the origin. The intersecting x- and y-axes divide the coordinate plane into four sections.

The origin is at 0 on the x-axis and 0 on the y-axis. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

The origin is used to determine the coordinates for every other point on the graph. It is generally the starting point on a grid.

In general, origin is the place where something comes from or the place where something originates.

Hence the value of the expression above are as listed below

<em>f(6+4) = 25</em>

<em>f(6)+f(4) = 20</em>

<em>f(6-4) = 1</em>

<em>f(6)-f(4) = 6</em>

<em>f(6*4) = 67</em>

<em>f(6)*f(4) = 91</em>

<h3>Functions and values</h3>

Given the expression below f(x) = 3x - 5

f(6+4) = f(10) =3(10) - 5

f(6+4) = 25

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)+f(4) = 13+7

f(6)+f(4) = 20

f(6-4) = f(2) =3(2) - 5

f(6-4) = 1

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)-f(4) = 13-7

f(6)-f(4) = 6

f(6*4) = f(24) =3(24) - 5

f(6*4) = 67

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)*f(4) = 13*7

f(6)*f(4) = 91

200 = 16(6t − 3) solve this and show the work please
amm1812

Answer:

t = 2.58333

Step-by-step explanation:

use the distributive property:

200 = 16(6t - 3)

multiply the 16 to each value in the parenthesis:

200 = 96t - 48

now add 48 to both sides:

200 = 96t - 48

+48            + 48

248 = 96t

now divide each side by 96:

248/96 = 96t/96

t = 2.583333

decimal form: 2.5833333

mixed number: 2\frac{7}{12}
