Answer:
When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.
First, multiply normally.
25x10x5
1100
Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.
So, the answer is -1100.

Answer: 12 gallons
Step-by-step explanation:
Use proportion to estimate how much gas she needs for 204 miles.
10:120=x:204
204*10=120x
x=2040/120
x=17 gallons
For 204 mile trip Trina needs 17 gallons of gas. She has 5 gallons.
17-5=12
She will need 12 gallons of gas.
Positive six and negative sixteen
Your answer is X (4
3x+3<15
3x<12
X<4
