Answer:
Easy Peasy!
Step-by-step explanation:
First we have to set up our equation:
(Let x= Temp. after 5 days)
Sorry, have to define variables. If I didn't do it in Middle School Tests, I get an automatic 0 for that question.
So, let's solve!
(If you didn't know what I did there, I just multiplied the rate of the decreasing and increasing temperature by the number of days it was in effect)
So, the temperature during the fifth day is 58.2 degrees.
Hope this helps!
P.S. Stay Safe!
Answer:
yes
Step-by-step explanation:
Yes this triangle is right angled and can be justified using the Pythagorean theorem. The theorem states that: . Substitute using the given values:
(9^2)+(12^2)=15^2
81 + 144 = 255
255 = 255.
It satisfies the theorem therefore it is a right angle triangle.
Divide both sides by -2. We know that since 2 is negative, it'll be < (less than) 0. So, the direction of inequality will change.
Divide 26 by -2..we'll get the answer as -13.
Now, subtract 3 from both the sides.
Subtracting -13 by 3..we'll get the answer as -16.
Divide both sides by 2. We know that since 2 is positive, the direction of inequality will remain the same.
Divide -16 by 2..we'll get the answer as -8.
