Hi there!

The answer is x = 6. All you have to do is subtract 83 from 127 because 127 is the total of the two parts of the equation. Now using the expression they give you - since you already know what the missing angle degree is for JKM- you just plug it in. 9x-10=44.

Add 10 to both sides to cancel out the ten.

You then have 9x = 54.

Divide both sides by 9.

Leaving you with x = 6.

Hope this helps !

Solve: <br> 3x+5-13x = 25

iragen [17]

3x+5-13x = 25
Subtract 13x from 3x
5 - 10x = 25
Subtract 5 from both sides
-10x = 20
Divide -10 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: -2

What's 1/4 of the way between point (-5,6) and point (7,2)

lesya692 [45]

Answer:

(-2, 5) or x = -2, y = 5.

Step-by-step explanation:

Using the Midpoint formula:

M = $(\frac{x_{1}+ x_{1} }{2}, \frac{y_{1}+ y_{1} }{2})$

and using the coordinates in your given question:

(-5, 6) and (7, 2):

The midpoint (or halfway point) between (-5, 6) and (7, 2) is:

M = $(\frac{-5 + 7 }{2}, \frac{2+ 6}{2})$ = $(\frac{2}{2} , \frac{8}{2} ) = (1, 4)$

To determine what is 1/4 of the way between points (-5, 6) and (7, 2), we can use Midpoint Formula to find the halfway point between one (-5, 6) and (1, 4):

M = $(\frac{x_{1}+ x_{1} }{2}, \frac{y_{1}+ y_{1} }{2})$

M = $(\frac{-5 + 1 }{2}, \frac{6+ 4}{2}) = (\frac{-4}{2}, \frac{10}{2})$ = (-2, 5).

Therefore, the 1/4 of the way between points (-5, 6) and (7, 2) is (-2, 5).

Which side of the equation 5t - 8 = 19t + 1 would you isolate the variable terms? Why?

il63 [147K]

We rewrite equations to make them simple or to solve them. Solving algebraic equations often means isolating the variable or rewriting the equation so that one expression is only the variable with a coefficient of 1
