Answer:
longer = 28 meters
Total = 40 meters
Step-by-step explanation:
Let the smaller piece be s,
and the longer piece be b
s = ¼b + 5
s = 12
¼b + 5 = 12
¼b = 7
b = 28 m
Total length = 28+12 = 40 meters
51/4=12.75.

Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age
x = 3y
x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
Answer:
4/5
Step-by-step explanation:
→ Rearrange to get into y = mx + c
5y = 4x + c
→ Divide everything by 5
y = 4/5x + c
We are given with two conditions and we label each positve number as x and y. The sum of the 2 numbers is x + y equal to S. The product is maximum.
The product is xy. To find the maximum
P = xy = x (S- x) = Sx - x2
dP = S - 2x = 0
hence x = S/2
y then is equal to S/2 also.
