Answer:
She used the addition property of equality:
p2 + 5 = 8p - 7
+7 +7
p2 + 12 = 8p
5/5=1, 1/2=0.5, After you divide the fractions you then only have to divide the numbers. 1/0.5=2
Move constant over (5x=38+2), combine terms (5x=40), divide both sides by 5 (x=8)
Answer:
A. 4000 meters because
1 km = 1000 meters
and 4 km = 1000 × 4 = 4000
............
First, let's find a common denominator.
12.
3 x 4 = 12 1 x 4 = 4 4/12
4 x 3 =12 1 x 3 = 3 3/12
3/12 + 4/12 = 7/12
3/4 = 8/12
8/12 - 7/12 = 1/12
So, your answer is 1/12.
Glad I could help, and good luck!
