P(9) is p9 or 9p (I think)
Answer:
- A. Since 11 ≠ 9, there is no solution
Step-by-step explanation:
<u>Given system:</u>
- 1.75x + 1.25y = 2.75
- 7x + 5y = 9
<u>Multiply the first equation by 4:</u>
- 4(1.75)x + 4(1.25)y = 4(2.75)
- 7x + 5y = 11
We get same equation as the second one with the difference that the right side equals to 11.
Since left sides are same and right sides are different, the system has no solution.
Correct choice is A
Part C. 19 and 8 are the 2 factors
WORK: since 56 + 96 = 152, and 152 goes into 8 19 times.
You just have to reverse the operations
1. -48-8= -56
2. -56/3= -18.66
ANSWER = -18.66
