We are asked to write a certain equation. Your first task is to read the statement thoroughly. If you've notice, the statement mentioned "a number". Let's assign x to be the number. First statment is twice a number (2x). Then, decreased by the quotient of that number and 2 (-x/2). Lastly, the statement at least 12 is written as >12. 

2x - (x/2) >12

<u>Step 1: Define</u>

f(x) = 3x - 1

f(x) = -7

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute:                    -7 = 3x - 1
  2. Isolate <em>x</em> term:              -6 = 3x
  3. Isolate <em>x</em>:                       -2 = x
  4. Rewrite:                        x = -2

Sec s = 1.6948
Anastaziya [24]
That'd be true only if the value of "s" is the exact same one for both
namely  if sec(s) = cos(s)
then solving for "s"
thus

\bf sec(s)=cos(s)\qquad but\implies sec(\theta)=\cfrac{1}{cos(\theta)}&#10;\\\\\\&#10;thus\cfrac{1}{cos(s)}=cos(s)\implies 1=cos^2(s)\implies \pm \sqrt{1}=cos(s)&#10;\\\\\\&#10;\pm 1=cos(s)\impliedby \textit{now taking }cos^{-1}\textit{ to both sides}&#10;\\\\\\&#10;cos^{-1}(\pm 1)=cos^{-1}[cos(s)]\implies cos^{-1}(\pm 1)=\measuredangle s

PLZ HELP ME NEED THIS FAST WILL GIVE BRAINLIEST
OleMash [197]

Answer: l = 60 ft and w = 30 ft

P = 2(l + w)

180 = 2(l + w)

Let x = width of his yard

Let 2x = length of his yard

180=2(2x+x)

\frac{180}{2}=\frac{2(2x+x)}{2}

90=3x

\frac{90}{3} =\frac{3x}{3}

x=30ft

l = 2x = 30(2) = 60 ft

Check:

180 = 2(l + w)

180 = 2(60 + 30)

180 = 2(90)

180 = 180

LS = RS
