1/2x+6-2x+1/2=7/2 find x show steps plz

Mathematics

Nesterboy [21]3 years ago

\frac{1}{2} x + \frac{1}{2} - 2x + 6 = \frac{7}{2}
- 2x + \frac{13}{2} + \frac{x}{2} = \frac{7}{2}
subtract 13/2 from both sides

- 2x + \frac{x}{2} = - 3
multiply both sides by 2

- 4x + x = - 6

x=2

Timed quiz help please! <br> 2 2/5 kilometers in 3 3/4 minuets.
shepuryov [24]

Answer: 16/25 (sorry I'm not really sure bc I'm just  a middle schooler)

Step-by-Step explanation:

2 2/5 km=2.4 kilometers

3 3/4 minutes=3.75 minutes

2.4/3.75=240/375

240/375=48/75=16/25=64/100=0.64

0.64 km/minute (0.64 km per minute)

you can solve the problem using the fractions...

2 2/5=12/5

3 3/4=15/4

(12/5)/(15/4)=(12/5)*(4/15)=48/75=16/25=0.64 again, or you can simplify before multiplying...

(12/5)/(15/4)=(12/5)*(4/15)=(4/5)*(4/5)=16/25...

How many triangles can be constructed with angles measuring 25 degree, 25, degree and 130
timofeeve [1]
<span>Answer: Option (C) More than one

Explanation:
All triangles must satisfy the following condition:

"The sum of all the angles of a triangle should be 180°."

25° + 25° + 130° = 180° (The condition of a triangle is satisfied.)

HOWEVER, keeping angles the same as above, we can construct "More than one" triangles by varying the lengths of a triangle.

For example:
By keep the three angles of a triangle 25°, 25° and 130°, the triangle with the three sides of lengths 10, 10, 18.13 (respectively) is same as the triangle with the three sides of lengths 1, 1, 1.81 (respectively). Likewise, you can construct infinite number of triangles. Therefore, the correct option is "(C) More than one."</span>

Normal probability Density Function Use a graphing utility to graph the model probability density function with µ = 0 and ð = 2,
Nuetrik [128]

Answer:

Step-by-step explanation:

Hello!

The standard deviation (δ) is a measure of variability, this means, it shows how dispersed the data set is with respect to the mean. The population mean (μ) is a measurement of position. The three graphics have the same position μ=0 but their standard deviations change, this means, the form of their bells is different. The greater the value of the standard deviation, the more dispersed the data is you can see this graphically because the width of the bell will be greater.

Graph attached.

I hope it helps!

PLSSSS HELPPP MEEEEEE!!! I REALLY NEED HELPPP ANSWER IT CORRECTLY PLSSS
igor_vitrenko [27]

Answer:

A stem and leaf plot shouldn't be used because the numbers are more than two digits long. These numbers are more varied, so it isn't correct for a stem and leaf plot. The stem is usually the tens digit, and the leaf is the ones digit. When you have four digits, it would get infinite times more hard and complicated. Hope that helped!
