Solve 3x+ 4x = 2. (2 points) O 2t10 O-2+2v10 3 O-2±10 3 O -41v10 3

1 answer:

3 0

3x+4x=2
You add 3x and 4x which gets you 7x

7x=2
You divide both sides of the equation by 7

x=2/7
This will be your result

What is the average score of runa 140,96 and 13?

scoundrel [369]

$\huge\textsf{Hey there!}$

$\large\textsf{Formula:}$

$\mathsf{\dfrac{Sum\ of\ all\ terms}{Total\ number\ of\ values\ in\ the\ data}= your\ mean/average}$

$\mathsf{\dfrac{140+96+13}{3}}$

$\mathsf{140+36+13}$

$\mathsf{140 + 96 = \bf 236}$

$\mathsf{236 + 13}$

$\mathsf{ = \bf 249}$

$\mathsf{\dfrac{249}{3}}$

$\mathsf{= \bf 83}$

$\boxed{\boxed{\large\textsf{Possible answer: \huge \bf 83}}}\huge\checkmark$

Can I have help with the question

sleet_krkn [62]

Answer:

Midpoint = (3.5, 4.5)

Perpendicular bisector = y = $\frac{7}{9}$ x + $\frac{16}{9}$

Step-by-step explanation:

[] We can solve this using the midpoint formula:

-> See attached

[] Plug-in our coordinates and solve:

$(\frac{7+0}{2} ,\frac{0+9}{2} )=(\frac{7}{2} ,\frac{9}{2} )=(3.5,4.5 )$

[] Now we will find the slope to solve for the perpendicular bisector.

-> We will use slope-intercept form, see attached

$\frac{9-0}{0-7}=\frac{9}{-7}$

-> The slopes of two perpendicular lines are negative reciprocals of each other, so $\frac{7}{9}$ will be the slope of or perpendicular bisector

-> Now we can solve for the equation by using y – y1 = m ( x – x1), were y1 and x1 are the coordinates of our midpoint

y - 4.5 = $\frac{7}{9}$ (x-3.5)

y - 4.5 = $\frac{7}{9}$ x- $\frac{49}{18}$

y = $\frac{7}{9}$ x- $\frac{49}{18}$ + 4.5

y = $\frac{7}{9}$ x + $\frac{16}{9}$

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

there are about 25000000000 red boold cells in the average adult. About how many adult would it take to have a total googol of r

IRISSAK [1]

A googol is 1.0*10^100. there are 25000000000 RBC in the average adult.
The number of adults equals
1.0*10^100 / 25000000000
=400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
(=10^100/(25*10^9)=4*10^89)
