Answer:
s=-4
Step-by-step explanation:
- combine like terms on each side and get 3s-12=6s
- subtract 3s from both sides to get -12=3s
- divide both sides by three and get s=-4
( (r+2) * (2r-9)-(r^2+17r+30) )/(r+2)
none of the parenthetical operations or power operations can be simplified further, so multiplication and division first, left to right:
(2r(r+2) -9(r+2) - r^2 + 17r +30)/(r+2)
(2r^2 + 2r -9r+18 -r^2 +17r +30 )/(r+2)
(r^2 +10r +48)/(r+2)
Temperature goes down up to 10° Celsius during the night.
Given that;
Temperature drop from 5º Celsius to -5º Celsius
Find:
Change in temperature in Celsius
Computation:
Change in temperature = Initial temperature in Celsius + Final temperature in Celsius
Change in temperature = 5 - (-5)
Change in temperature = 5 + 5
Change in temperature = 10° Celsius

That's the associative property of addition
it is normally written as
(a+b)+c=a+(b+c)
which is like what you have
(17+4)+9=17+(4+9)
Answer:
m∠1 = 106
Step-by-step explanation:
Given: m∠5 = 106
Vertical angles are congruent
The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.
Therefore: m∠1 = 106
