Supplementary means adds to 180
A+B=180
B=73
A+73=180
minus 73 both sides
A+73-73=180-73
A+0=107
A=107
A=107 degrees
25%. 60 divided by 15 is 4, thus 15 is 1/4 of 60. 1/4 can also be expressed as 25%
Answer:
Step-by-step explanation:
It asks for the common set of A and B.
<u>There only one element common to both the given sets:</u>
- A={2,3,5,7} and B={2,4,6,8} ⇒ A∩B = {2}
First lets figure out 2 and 1/4 as a decimal
2 and 1/4 = 2.25
So now we subtract
5 - 2.25 = 2.75
She is 2.75 miles away from her starting point

Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 5, 4 ) and (x₂, y₂ ) = (2, - 3 )
m = 
Her error was subtracting 5 from 2 instead of - 5 from 2
m =
=
= - 1 ← corrected solution
