Answer:
Step-by-step explanation:
We want to simplify the algebraic expression:
We can rewrite this as:
We convert to equivalent fractions to get::
We can now add the numerators and keep one of the denominators.
We rewrite as:
Answer:
(5/7 - 1) * (2/3 + (1/6 - 1/9) * 18/5 + 1/15) - (2/7 + 1/3) * (-7/13)
= (5/7 - 7/7) * (2/3 + (3/18 - 2/18) * 18/5 + 1/15) - (6/21 + 7/21) * (-7/13)
= (-2/7) * (2/3 + 1/18 * 18/5 + 1/15) - 13/21 * (-7/13)
= (-2/7) * (2/3 + 1/5 + 1/15) + 7/21
= (-2/7) * (10/15 + 3/15 + 1/15) + 1/3
= (-2/7) * 14/15 + 1/3
= -4/15 + 1/3
= -4/15 + 5/15
= 1/15
<u>Answer:</u>
<h2>d ≈ 7.07</h2>
<u>Steps:</u>
d = √( (3-(-2))² + (-1-4)² )
d = √( (3+2)² + (-1-4)² )
d = √( 5² + (-5)² )
d = √( 25 + 25 )
d = √50
<h2>d ≈ 7.07</h2>
Y=25x is proportional. Unit rate is 25
The other 2 aren't because they have a y-intercept and don't cross the orgin
