Solve the following equation algebraically show the steps: <br><br><br> n/3 -5 = 5

Lana71 [14]

$\longrightarrow{\green{ \: n = 30 }}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\frac{n}{3} - 5 = 5$

➼ $\: \frac{n}{3} = 5 + 5$

➼ $\: \frac{n}{3} = 10$

➼ $\: n = 10 \times 3$

➼ $\: n = 30$

Therefore, the value of n is 30.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$\frac{30}{3} - 5 = 5$

✒ $\: 10 - 5 = 5$

✒ $\: 5 = 5$

✒ $\: L.H.S.=R. H. S$

Hence verified.

The perimeter of a rectangle is 68 ft.

inessss [21]

Let the length be 9x and the width = 8x
Perimeter = 2(l + w) = 2(9x + 8x) = 2(17x) = 34x = 68
x = 68/34 = 2
9x = 9(2) = 18 ft
8x = 8(2) = 16 ft
Therefore, dimensions are 18 ft by 16ft

Which is the solution to 5^x=8^x-7

Levart [38]

Answer:

C) 30.9702

Step-by-step explanation:

Take log of both sides:

In5^x = In8^x - 7

Rewrite it using the laws of log:

xIn5 = (x - 7)In8

x / (x - 7) = ln 8 / ln 5

x / (x - 7) = 1.292

x = 1.292x - 9.044

1.292x - x = 9.044

x = 9.044 / 0.292

Thus, x = 30.9702
