Answer:
25°, 65°
Step-by-step explanation:
Essentially, you want two angles that have a sum of 90 degrees and a difference of 40 degrees.
The smaller is half the sum less half the difference: 90/2 -40/2 = 45 -20 = 25.
The larger is half the sum plus half the difference: 90/2 +40/2 = 45 +20 = 65.
Of course, once you know either value, you can add or subtract the difference (as needed) to find the other value.
The two angles are 25° and 65°.

<em>Additional comment</em>
There are many ways you can arrive at this conclusion. Algebraically, we can write ...
a+b = sum
a-b = difference
Adding these two equations gives ...
2a = sum +difference
Multiplying by 1/2, we get ...
a = 1/2sum +1/2difference . . . . . . as described above
Subtracting the difference gives ...
b = a -difference = 1/2sum -1/2difference
Answer:
<h3>-12 + 25 </h3>
As it is given in the question that 12° F is below zero is it is taken as minus and 25 °F is risen so it is taken as positive
Answer:
Therefore, after 12 years the car will value $6,765.35.
Step-by-step explanation:
Equation A.
Paul's plumbing: y= 40h+ 90
Perfect plumbing: y= 55h + 60
B:
Pauls plumbing: y= 40(3) + 90.... 310= y
Perfect plumbing y= 55(3) + 60... y= 225
