Answer:
w = -10
Step-by-step explanation:
w + 4 = (-6)
Subtract 4 from each side
w+4-4 = -6-4
w = -10
length = 15
let the width = w then length = 2w - 3
Perimeter = 2(length + width)
= 2(2w - 3 + w) = 2( 3w - 3) = 6w - 6 = 48
hence 6w = 48 + 6 = 54 ⇒ w =
= 9
Thus length = 2w - 3 = (2× 9) - 3 = 18 - 3 = 15
Answer: Mary is correct.
9/8 is an improper fraction, so we change it to 1 1/8.
Mary lives less than a mile from school, so we know that Thad lives farther since he lives a mile and 1/8 away, and Mary only lives 6/10 away, which is less than a mile.
Glad I could help, and good luck!
