Answer 1

Answer:

Answer:

x = 8
AM = BM = 16

Step-by-step explanation:

Your problem setup is correct. The triangle is isosceles, so the marked segments are the same length.

3x - 8 = 2x

You can solve this by subtracting 2x (from both sides) ...

x - 8 = 0

Then adding 8 (to both sides):

x = 8

MB = MA = 2x = 16.

Change the fraction 1/5 to a percent

Answers

A fraction is a short way to write a division problem.

Whenever you see a fraction, it means

(the top number) divided by (the bottom number).

When you pick up your pencil or your calculator and actually do the
division, the answer to the division is the decimal form of the fraction.

To change that fraction 1/5 to a decimal, divide 1 by 5 .

Then, to change the decimal to a percent, move the
decimal point 2 places that way ==>.

Answers

Since we are estimating, round to 60,000,000,000. Now count how many decimal places you would have to move to the left to get to a single digit (until we get to 6.0). That will be your exponent...

Which is a solution to (x – 3)(x + 9) = –27?

x = –9
x = –3
x = 0
x = 6

Answers

If you would like to solve (x – 3)(x + 9) = –27, you can do this using the following steps:

(x – 3)(x + 9) = –27
x^2 + 9x - 3x - 27 = -27
x^2 + 6x - 27 + 27 = 0
x^2 + 6x = 0
x * (x + 6) = 0
1. x = 0
2. x = -6

The correct result would be x = 0.

By evaluating the quadraticexpression at each realnumber, we conclude that x = 0 is a solution (root) to (x - 3) · (x + 9) = -27. (Correct choice: C)

How to find the roots of a given polynomic expression

In this question we must find a solution for a polynomicexpression. There are several approaches to find them. Since we have a polynomicexpression as a product of binomials, we can determine the solution by evaluating at each choice:

x = 0

(0 - 3) · (0 + 9) = -27

(-3) · 9 = -27

-27 = -27

By evaluating the quadraticexpression at each realnumber, we conclude that x = 0 is a solution (root) to (x - 3) · (x + 9) = -27. (Correct choice: C)

The following data are arranged in ascending order and the median of the data is 60.Find the value of x.
26, 29, 42, 53, x, x + 2, 70, 75, 82, 93

Answers

The median of the data is 60. That means the two middle numbers divided by 2 = 60.

(x + x + 2) / 2 = 60...multiply by 2
2x + 2 = 120
2x = 120 - 2
2x = 118
x = 118/2
x = 59

x + 2 = 59 + 2 = 61

so ur numbers go : 26,29,42,53,59,61. 70, 75, 82, 93
