Degger [83]
One may note the country's name is not finline or Finley, is Finland.

so, in short, if we take 137 to be the 100%, how much is 18.036 in percentage off of it?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
137&100\\
18.036&x
\end{array}\implies \cfrac{137}{18.036}=\cfrac{100}{x}\implies x=\cfrac{18.036\cdot 100}{137}

Solve each equation for the ind<br>2. 2(x-7)=10​
SVETLANKA909090 [29]

Answer:

x= 12

Step-by-step explanation:

2(x-7) = 10

Distribute the 2. 2x-14 = 10

Add the 14 onto both sides to cancel it out on the original side and following the rules- the same must be done to the other side. 2x-14 (+14) = 10+14 -----> 2x = 24

Divide both sides by 2 to get the X alone. 2x/2 = 24/2 ---------> x= 12
