Answer:

-243

Step-by-step explanation:

${( - 3)}^{ - 5} = \frac{1}{x} \\ \\ \therefore \: \frac{1}{ {( - 3)}^{ 5} } = \frac{1}{x} \\ \\ \therefore \: {( - 3)}^{ 5} = x \\ \\ \therefore \: - 243 = x \\ \\ \huge \red{ \boxed{\therefore \: x = - 243}}$

How do you solve 10+5(3x-4)=2x+7

Taya2010 [7]

Answer:

$x=1\dfrac{4}{13}$

Step-by-step explanation:

Given the equation

$10+5(3x-4)=2x+7$

Use distributive property:

$10+5\cdot 3x-5\cdot 4=2x+7\\ \\10+15x-20=2x+7$

Use commutative property to rewrite the equation:

$15x+10-20=2x+7$

$15x-10=2x+7$

Add 10 th both sides:

$15x-10+10=2x+7+10\\ \\15x=2x+17$

Subtract $2x:$

$15x-2x=2x+17-2x\\ \\13x=17$

Divide by 13:

$x=\dfrac{17}{13}=1\dfrac{4}{13}$

Solve the equation. Use a calculator. c3 = 4 (Round to the nearest tenth as needed.)

Sergeeva-Olga [200]

To isolate the variable you would divide both sides of the equation by 3, resulting in the equation to answer c = 4/3 or c = 1.3

Solve for the variable r

Sonja [21]

Answer:

see explanation

Step-by-step explanation:

Given

V = πr²h ( isolate r² by dividing both sides by πh )

$\frac{V}{h\pi }$ = r² ( take the square root of both sides )

$\sqrt{\frac{V}{h\pi } }$ = r
