Answer:

10.2

Step-by-step explanation:

Using Pythagoreans theorem, i did A^2 + B^2 = C^2

in this case,

4^2 + x^2 = 11^2

16 + x^2 = 121

x^2 = 105

square root both sides

you get 10.2469508

or 10.2

So since 2/5 of the washing machines have been sold that means 3/5 remain in the store 
 
first find the number of washing machines that were in the store before any were sold 

X is the number of washing machines in the store before selling

18=(3/5)X

18/(3/5)=X
X=18*(5/3)
X=30

so at the beginning there were 30 machines

then multiply the percent sold (2/5) by the number at beginning to find the number sold

(2/5)*30=12

so 12 machines were sold

to find the cost per machine divide the total price by number of machines sold so 

$3840/12= $320 

so the answer is $320 per machine

2[3x-(4x-6)]=5(x-6)<br>Solve and answer the linear equation.
OleMash [197]

Answer: x = 6

<u>Step-by-step explanation:</u>

2[3x - (4x - 6)] = 5(x - 6)

2[3x - 4x + 6] = 5x - 30

2[-x + 6] = 5x - 30

-2x + 12 = 5x - 30

<u>+2x        </u>  <u>+2x        </u>

        12 = 7x - 30

      <u>+30 </u>  <u>      +30 </u>

        42 = 7x

         \frac{42}{7} = \frac{7x}{7}

          6 = x

-(3/4)+1 7/8 divided by 1/2 =n
VashaNatasha [74]

first off, let's convert the mixed fraction to improper fraction and then proceed, let's notice that by PEMDAS or order of operations, the multiplication is done first, and then any sums.

\stackrel{mixed}{1\frac{7}{8}}\implies \cfrac{1\cdot 8+7}{8}\implies \stackrel{improper}{\cfrac{15}{8}} \\\\[-0.35em] ~\dotfill\\\\ -\cfrac{3}{4}~~ + ~~\cfrac{15}{8} \div \cfrac{1}{2}\implies -\cfrac{3}{4}~~ + ~~\cfrac{15}{8} \cdot \cfrac{2}{1}\implies -\cfrac{3}{4}~~ + ~~\cfrac{15}{4} \\\\\\ \cfrac{-3+15}{4}\implies \cfrac{12}{4}\implies 3

EG=EF

EG=20*(2\frac{1}{2})=20*\frac{5}{2}=50\ ft
