answer:

  • n = -\frac{3}{2}

Explanation:

→ 4(n+10) = 34

→ \frac{4(n+10)}{4}  = \frac{34}{4}

→ n + 10 = \frac{17}{2}

→ n = \frac{17}{2} -10

→ n = \frac{17-20}{2}

→ n = \frac{-3}{2}

How long will it take 5000 to double in an account that pays 5.6% simple interest
Ganezh [65]
So... doubling 5000 is just 10,000, thus

\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$10,000\\
P=\textit{original amount deposited}\to& \$5,000\\
r=rate\to 5.6\%\to \frac{5.6}{100}\to &0.056\\
t=years
\end{cases}
\\\\\\
10000=5000(1+0.056t)\implies \cfrac{10000}{5000}=1+0.056t
\\\\\\
2=1+0.056t\implies 1=0.056t\implies \cfrac{1}{0.056}=t

nekit [7.7K]

Answer:

10 / 38

Step-by-step explanation:

Black socks = 9

White = 10

Total = 10 + 9 = 19

Choosibg without replacement :

P(white) = 10 / 19

Second pick:

P(black) = 9 / 18 = 1/ 2

P(white then black) = 10/19 * 1/2 = 10/38

marta [7]

Answer:

Step-by-step explanation:

4(5x-2y=9)

-2(3x+4y=-5)

20-20x-8y=36

+6x-6x-8y=10

36-20x=10+6x-6x

36-36-20x-6x=10

-26x=10-36

-26x/-26=-26/-26

x=1

What are the solutions of the quadratic equation (x + 3)(x +3) = 49? Ax = -2 and x = -16 Bx = 2 and x = -10 Cx = 4 and x = -10 D
Ivahew [28]

Answer:

4 and -10

Step-by-step explanation:

\displaystyle (x + 3)(x +3) = 49 \\ x^2+3x+3x+9=49 \\ x^2 +6x+9=49 \\ x^2 + 6x + 9 - 49 = 0 \\x^2+6x-40=0 \\\\ \Delta=b^2-4ac \\ \Delta=6^2-4 \cdot 1 \cdot (-40) \\ \Delta=36+160 \\ \Delta=196 \\ \\ X_{1,2}=\frac{-b \pm \sqrt{\Delta} }{2a}  \\ \\ X_1=\frac{-b+\sqrt{\Delta} }{2a} = \frac{-6+14}{2} = \frac{8}{2}=4 \\ \\ X_2=\frac{-b-\sqrt{\Delta} }{2a}  = \frac{-6-14}{2}=\frac{-20}{2} = -10
