-5 = b -2/3<br><br> b= __<br><br> Please help!

Inga [223]

Answer:

b = - $4\frac{1}{3}$

or

b = - $\frac{13}{3}$

Step-by-step explanation:

-5 = b - $\frac{2}{3}$

Add $\frac{2}{3}$ to both sides of the equation to get rid of the "- $\frac{2}{3}$ " on the right side.

-5 + $\frac{2}{3}$ = b - $\frac{2}{3}$ + $\frac{2}{3}$

Simplify

- $4\frac{1}{3}$ = b

b = - $4\frac{1}{3}$

or

b = - $\frac{13}{3}$

What is the median of these numbers i know how to find it with an odd number but this is an even number

Naily [24]

64, 68, 71, 87, 215, 215

To find the median, we must find put the data set in order from least to greatest.

Great! We already have it like that :)

Now, our median is in between 71 and 87

So, basically, we have to find what the median of 71 and 87 are.

Simply add the two numbers together, and then divide it by 2.

71 + 87 = 158

158 ÷ 2 = 79

So, 79 is your median!

Find the midpoint of the segment with the given endpoints. ( 7,7) and ( 0 −3)

gizmo_the_mogwai [7]

Answer:

-The result for the midpoint:

$(\frac{7}{2},5)$

Step-by-step explanation:

-To find the midpoint, you need this formula:

$(x_{m},y_{m}) = (\frac{x_{1}-x_{2}}{2},\frac{y_{1}-y_{2}}{2})$

-Next, the two points (7,7) and (0,-3) for the formula:

$(\frac{7-0}{2},\frac{7+3}{2})$

-Then, you solve it:

$(\frac{7-0}{2},\frac{7+3}{2})$

$(\frac{7}{2},\frac{10}{2})$

$(\frac{7}{2},5)$

-So, therefore, the answer is $(\frac{7}{2},5)$ .
