Answer:
66 °F
Step-by-step explanation:
At 4 P.M., the temperature had decreased by 3° from the temperature at 3 P.M., so was ...
4 P.M. temp = 78 °F -3° = 75 °F
This was repeated until 7 P.M.
5 P.M. temp = 75 °F -3° = 72 °F
6 P.M. temp = 72 °F -3° = 69 °F
7 P.M. temp = 69 °F -3° = 66 °F
The temperature at 7 P.M. was 66 °F.

Of course the repeated subtraction can be simplified using multiplication. The subtraction of 3° four times is equivalent to the subtraction of . . .
(3°)(4) = 12°
That is, the temperature at 7 P.M. is ...
78 °F -3°×4 = 78 °F -12° = 66 °F
Answer:
3.33..
Step-by-step explanation:
x2-8x=9
x-6x=9
-5x=9
x=-5/9
(-5/9)(2)-8(-5/9)=3.33.. (3 and 1/3)
The answer you're looking for is s=6.
by substitution you'd get 6.
The correct answer is x=3. Hope this helps!!
