Answer:
A=47 Degrees
Step-by-step explanation:
all triangles add up to 180 degrees
exterior angles add up to 180
360-100+127
360-227
133=B
180-133=47
A=47 Degrees
Answer:
-3/2
Step-by-step explanation:
The slope is the ratio of rise to run, the change in y divided by the change in x. It is often designated by the letter "m".
m = (change in y)/(change in x) = (-7 -(-1))/(5 -1) = -6/4
m = -3/2
The slope of the line through the given points is -3/2.
You have to distribute the 3.
3*4x , 3*-5
12x - 15
Hope this helps :)
35/72. Multiply numerators and then multiply denominators then simplify. :)
Answer:
Step-by-step explanation:
I am assuming that '.31' is the repeating pattern.
<h3>Setting up equation one:</h3>
<h3>Setting up equation two:</h3>
There are two digits in the repeating group. I multiplied the first equation my 100 to get:
Subtract equation one from equation two:
'100x-231.3131..' - 'x = 2.313131... ' = '99x = 229'
Solve for X:
