$~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$237.90\\ P=\textit{original amount deposited}\dotfill & \$1525\\ r=rate\to 2.6\%\to \frac{2.6}{100}\dotfill &0.026\\ t=years \end{cases} \\\\\\ 237.90 = (1525)(0.026)(t)\implies \cfrac{237.90}{(1525)(0.026)}=t \implies 6=t$

Can you please help me on -5(x+2)=-(-5x+1)-x

PilotLPTM [1.2K]

Answer:

x = -1

Step-by-step explanation:

Step 1: Distribute

-5(x + 2) = -(-5x + 1) - x

-5x - 10 = 5x - 1 - x

-5x - 10 = 4x - 1

Step 2: Solve for x

-5x - 10 + 5x = 4x - 1 + 5x

-10 + 1 = 9x - 1 + 1

-9 / 9 = 9x / 9

-1 = x

Answer: x = -1
