Answer:

The radius would be 4.8

Step-by-step explanation:

The circumerfence of a circle can be found use the equation C=2 $\pi$ r. So since we are given the circumerce we need to rearrange the eqaution to it looks like $\frac{30}{2\pi }$ =r. when we do this out we find that the radius equals 4.8.

Answer:

-5/ (x^19 * y^12)

Step-by-step explanation:

-15x^-10 * y ^ -3 * x^-9 * y^-9/3 (It's writing it like this.)

15 and 3 have a GCF of 3.

-5x^-10 * y^-3 * x^-9 * y^-9/1

Reduce similar occurrences. *twice in a row*

-5x^(-10 + (-9)) * y^(-3 + (-9))/1

Remove extra signs *twice in a row*

-5x^(-10 - 9) * y^(-3 - 9)/1

Remove extraneous 1.

-5x^(-10 - 9) * y^(-3 - 9)

Add integers.

-5x^-19 * y^-12

Negative powers change multiplication to division.

-5 / (x^19 * y^12) is the final answer.

Even with that, the simplified answer wouldn't have negative exponents because of the negative powers rule.

5(2x – 3) = 5 Part A: How many solutions does this equation have? (4 points) Part B: What are the solutions to this equation? Sh

Maru [420]

ANSWER

a) One Solution

b) the solution is x=2

EXPLANATION

The given equation is:

$5(2x - 3) = 5$

We expand to get;

$10x - 15 = 5$

Group similar terms;

$10x = 15 + 5$

This implies that,

$10x = 20$

Divide both sides by 10 to obtain,

$x = 2$
