First answer choice
Reducing the second equation by a factor of 2 will give 2x+y=11
Then y=11-2x
And you can substitute that into the first equation for The answer.
Final answer:
Choice 1
Answer:
She used the addition property of equality:
p2 + 5 = 8p - 7
+7 +7
p2 + 12 = 8p
Answer:
11/15
Step-by-step explanation:
22/30 = 11/15 because they both have a common factor of 2 in the numerator and denominator.
1: Subtract 15 from both sides. 5x=13.
2: Divide both sides by 5.
Answer: 2.6, which is equal to 13/5. The answer is B.
