Answer:
(3,2)
Step-by-step explanation:
A: (3,2)
Since A lies on the mirror line, it will mapped onto itself
A': (3,2)
Let width be x,
Length: 3+x
P=2(l+w)
54=2(x+(x+3))
54/2=2x+3
27=2x+3
27-3=2x
24=2x
24/2=x
12=x
Therefore, the width is 12 inches and the length is (12+3)=15 inches
Hope I helped :)
Answer:
Substitution
Step-by-step explanation:
1. PQ = RS --------Given
2. PQ + QR = QR + RS ---------Addition Postulate
3. PQ + QR = PR;
QR + RS = QS -------Segment Addition
4. PR = QS ------- Substitution
Assuming that the wage of $12.50 an hour applies to Greg and Darius as a team instead of individually, 9 hours of work would have gotten them:
$12.50/hour × 9 hours = $112.50
If they split the wage in half among themselves, then Greg would have
$112.50 ÷ 2 = $56.25
such that if he spent $15 of it (assuming that's the only money he has), he would now have:
$56.25 - $15 = $41.25
∴ Greg now has $41.25.
