So the two possible original temperatures would be either -9 or 9.
Answer:
4. D
5. A
Step-by-step explanation:
For #4, I first divided 15 by 4 and saw what the greatest whole number it was divisiable by. Then I wrote the remain as a fraction
For #5, I first multiplied by 4*6 and then add 5 to that answer
(3,-1) just fill it in and the only one that makes sense is the first one
I believe it is, 9/5.
Mixed fraction: 1 4/5.
Answer:
-17/2 =x
Step-by-step explanation:
9–5(x+4)=3(2–x)
Distribute
9 - 5x - 20 = 6 -3x
Combine like terms
-5x-11 = 6-3x
Add 5x to each side
-5x-11 +5x = 6-3x+5x
-11 = 6+2x
Subtract 6 from each side
-11-6 = 6+2x-6
-17 = 2x
Divide by 2
-17/2 = 2x/2
-17/2 =x
