answer:
1. yes
2. no
3. yes
4. no
step-by-step explanation:
- for 1, yes because no matter what they are the signs are still the same
- for 2, no because the signs have changed — 2/5 is positive now
- yes because even though there is addition now, the signs are the same. when you use kcc (keep change change), the sign changes to +
- no, because the coefficient for p is changed, which won't be true or give us the same result
Answer:
= 8.25
Step-by-step explanation:
6, 8, 8.5, 11
The middle number are 8 and 8.5
We then add them and divide by 2
= 8 + 8.5 / 2
= 16.5/2
= 8.25
Using the variable x for the unknown number,
20 - (x + 4) = 6
is your answer!
Hope I helped :)
