Life savers yummies, skittles mark i think
Step-by-step explanation:
It should be the last one but sorry if i’m wrong
Answer:
- Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Step-by-step explanation:
<u>Given expressions</u>
- 4x - x + 5 = 3x + 5
- 8 - 3x - 3 = -3x + 5
Compared, we see the expressions are different as 3x and -3x have different coefficient
<u>Answer options</u>
Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.
- Incorrect. Positive outcome doesn't mean equivalent

Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
- Incorrect. There are 2 values- variable and constant

Answer:
2 miles
Step-by-step explanation:
distance=rate*time
d=rt
1/6=r*(1/12)
multiply both sides by 12
12(1/6)=r*(1/12)12
2=r*1
2=r
rate=2 miles per hour
