Answer:

x = -1

Step-by-step explanation:

Expand Brackets

( x - 5 ) ( - 3 ) = 18

- 3 x + 15 = 18

(-15 from both sides)

-3 x = 3

(÷ -3 from both sides)

x = -1

Answer:

x = - 1

Step-by-step explanation:

Given

(x - 5)(- 3) = 18

Divide both sides by - 3

x - 5 = - 6 ( add 5 to both sides )

x = - 1

distribute the left side by - 3

- 3x + 15 = 18 ( subtract 15 from both sides )

- 3x = 3 ( divide both sides by - 3 )

x = - 1

Remember, a/(c/d)=(a)(d/c)
subsitute 1/2 for x

$f(x)=\frac{1}{\frac{1}{2}}=(1)(\frac{2}{1})=2$

What percent of 72 is 27?

Alina [70]

if we take 72 as the 100%, what is 27 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 72&100\\ 27&x \end{array}\implies \cfrac{72}{27}=\cfrac{100}{x}\implies \cfrac{8}{3}=\cfrac{100}{x}\implies 8x=300 \\\\\\ x=\cfrac{300}{8}\implies x=\cfrac{75}{2}\implies x=37.5$

The perimeter of a triangle is 84m. the longest side of the triangle is 7m less than twice the length of the shortest side, x. t

Masja [62]

Side1 + side2 + side 3 = 84

side1 is the shortest side, and its length is x.
side2 is the middle side, and its length is x + 7
side3 is the longest side, and its length is 2x - 7

x + x + 7 + 2x - 7 = 84

4x = 84

x = 21

side1 = x = 21
side2 = x + 7 = 21 + 7 = 28
side3 = 2x - 7 = 2(21) - 7 = 42 - 7 = 35

The length of the sides are 21 m, 28 m, and 35 m.
