Solve the equation: 1/2(4x - 16) = 14
what is x
x = 11

x = 3.75

x = -2

x = 5

Answers

Answer 1

Answer:

        x = 11

Step-by-step explanation:

1/2(4x - 16) = 14

2x - 8 = 14             {add 8 to both sides}

 2x = 22               {divide both sides by 2}

   x = 11

A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?

Answers

Without replacement, the probability that all three marbles drawn will be red is 0.01.

What is the probability?

Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.

Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)

5/17 x 4/16 x 3/15 = 0.01

The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%

How to calculate probability?

We are given;

Number of red marbles = 5

Number of blue marbles = 8

Number of Green marbles = 4

Total number of marbles = 5 + 8 + 4

Total number of marbles = 17

Probability of first being red = 5/17

Probability of second being red = 4/16

Probability of third being red = 3/15

Thus;

P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)

P(all three marbles drawn are red) = 0.0147

Approximating to nearest tenth of a percent = 0.015 = 1.5%

solve 2x+6=34 i have no idea pls exsplain and help me :)

Answers

You want to try to isolate the x:
First subtract 6 from both sides so you get 2x=28

Then divide both side by 2 so you get x=14 which is your answer :)

ANSWER: x=14

Answer:

14

Step-by-step explanation:

okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this

so you’re gonna start off by separating the 2x from the 6=34.

now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)

now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.

2 x 14 + 6 = 34?

2 x 14 = 28 + 6 = 34.

34 = 34

so, x is 14. hope this helped!

Answer and explanation:

Given that 1/2cm= 1 foot

5cm= 2×5=10 feet

Length is twice the width, therefore real length of shape = 10×2=20 feet

Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet

What is the area of this triangle?
A=bh2


a-54 cm²

b-90 cm²

c-108 m²

d-216 m²

Answers

Answer:

a

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 9 and h = 12 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

It’s a because 12x9=108 then divide it by 2 and you have 54
