Solve -3^-5.

Knowing that $x^{-1} = \frac{1}{x}$ , then $-3^{-5}= \frac{-1}{243}$

That means that x = -243.

?/0.6=1.4 how to show the solution

den301095 [7]

To find the solution to this problem, you would do the opposite of division which is multiplication.

Use the terms you have to plug into your new equation;

0.6 x 1.4 = .84

To check your work you would plug in .84 where the '?' is;

.84/.6= 1.4

There you have the original equation you began with.

Therefore, .84 would be your final answer.

Which equation has exactly one solution in common with the equation y=6x-2?

GalinKa [24]

Answer:

A. 18x - 3y = 6

Step-by-step explanation:

By taking 3 common from the terms 18x and 3y we get,

3 (6x-3y) = 6

or, 6x - y = 6/3

or, 6x - y = 2

And,

The equation becomes,

y = 6x - 2

I need help on my warm up!! pls thx!

xxMikexx [17]

Step-by-step explanation:

$\tt{30.16 = 17.56 + 5x}$

Swap the sides of the equation :

⤑ $\tt{17.56 + 5x = 30.16}$

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ $\tt{5x + 17.56 - 17.56 = 30.16 - 17.56}$

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ $\tt{5x = 12.6}$

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ $\tt{ \frac{5x}{5} = \frac{12.6}{5}}$

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

$\pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ

What is the value of c? O 4 units O 5 units O 6 units O 7 units

Aleksandr [31]

The value of c is 5 units.

Step-by-step explanation:

Given,

WY = a = 4

ZY = b = 3

As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c

$a^2+b^2=c^2\\(4)^2+(3)^2=c^2\\16+9=c^2\\c^2=25$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{25}\\c=5$

The value of c is 5 units.
