What is 14=9-x I am trying to solve it

1 answer:

6 0

14 = 9 - x

First, subtract 9 from both sides.

14 - 9 = (9 - 9) - x
5 = -x

Now divide both sides by -1.
5/-1 = -1/-1x
-5 = x

The answer is x = -5.

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1

lora16 [44]

The value of x is 1/5

Step-by-step explanation:

In a probability distribution, probability should be between 0 and 1. The probabilities add up to one.

Given probabilities are:

$\frac{1}{10}, \frac{1}{5}, \frac{1}{2}, x$

The sum of these probabilities will be equal to 1.

So,

To find x,

$\frac{1}{10}+\frac{1}{5}+\frac{1}{2}+x = 1\\\frac{1+2+5}{10}+x=1\\\frac{8}{10}+x=1\\x= 1- \frac{8}{10}\\x = 1- \frac{4}{5}\\x= \frac{5-4}{5}\\x=\frac{1}{5}$

The value of x is 1/5

Jennifer is making bouquets of flowers. She has 25 roses, 45 tulips, and 15 snapdragons. She divides the flowers equally to make

chubhunter [2.5K]

Answer:

a. 3

Step-by-step explanation:

The number of flowers should be divisible by the number of bouquets.

Since

$25 = 5 \times 5 \\ 45 = 5 \times 9 \\ 15 = 5 \times 3$

there should be 5 bouquets, and each bouquet has 5 roses, 9 tulips and 3 snapdragons.

so the answer is

a. 3

On a coordinate plane, triangle T V W has points (negative 4, 8), (0, 4), and (4, 4).

Vanyuwa [196]

The coordinates of the endpoints of line segments T'V' are; T'(-1, 2) and V'(0, 1).

<h3>What are the coordinates of the endpoints of the segment T'V'?</h3>

It follows from the task content that the transformation involved in the formation of the image from the pre-image is dilation by a scale factor of 1/4.

On this note, given that the coordinates of T and V from the task content are; (-4, 8) and (0,4), it follows that the coordinates of the endpoints as required are; T'(-1, 2) and V'(0, 1).
