bogdanovich [222]1 year ago
3 0

Answer: \Large\boxed{\dfrac{3}{8} }

Step-by-step explanation:

<u>Given information</u>

b=2

c=-\dfrac{7}{4}

<u>Given expression </u>

b-(-\dfrac{1}{8}) +c

<u>Substitute values into the expression</u>

=(2)-(-\dfrac{1}{8}) +(-\dfrac{7}{4} )

<u>Convert the fractions into the common denominator</u>

<em>Least Common Multiple (LCM) of 8 and 4 = 8</em>

=(2)-(-\dfrac{1}{8}) +(-\dfrac{7\times2}{4\times2} )

=(2)-(-\dfrac{1}{8}) +(-\dfrac{14}{8} )

<u>Simplify the parenthesis</u>

=2+\dfrac{1}{8} -\dfrac{14}{8}

<u>Simplify by addition</u>

=\dfrac{16}{8} +\dfrac{1}{8} -\dfrac{14}{8}

=\dfrac{17}{8}  -\dfrac{14}{8}

<u>Simplify by subtraction</u>

\Large\boxed{=\dfrac{3}{8} }

Hope this helps!! :)

The function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

<h3>How to write a function of the length z in meters of the side parallel to the wall?</h3>

The given parameters are:

Perimeter = 210 meters

Let the length parallel to the wall be represented as z and the width be x

So, the perimeter of the fence is

P = 2x + z

This gives

210 = 2x + z

Make x the subject

x = 1/2(210 - z)

The area of the wall is calculated as

A = xz

So, we have

A = 1/2(210 - z) * z

This gives

A = z/2(210 - z)

Rewrite as

A(z) = z/2(210 - z)

Hence, the function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

Help!!!<br> Slove for x.<br> A.11<br> B.9<br> C.13<br> D.14
olga nikolaevna [1]

Answer:

Step-by-step explanation:

The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.

7/(x + 7) = 6/(15 + 6)         Cross Multiply after combining

7 / (x + 7) = 6/(21)                

6 * (x + 7) = 7 * 21             Remove the brackets

6x + 42 = 147                   Subtract 42

6x = 147 - 42

6x = 105                           Divide by 6

x = 17.5

I think I've done this correctly. If you find an error, please let me know and I'll open it for editing.
