Answer: No, 40 months isn’t reasonable.
Step-by-step explanation:
For Shellie: 40*3 = 120 cm in 40 months
For Carley: 40*2 = 80cm in 40 months
Next we add the amount of hair they have already to the amount of centimeters would grow.
Shellie: 120+10 = 130cm
Carley: 80+20 = 100cm
So if the girls wanted to cut their hair at the exact length, 40 months isn’t a reasonable solution.
Answer:
150 m and 50 m
Step-by-step explanation:
l= 125 m
w= 75 m
P= 2(125+75)= 400 m
A= 125*75= 9375 m²
l1= 125+25= 150 m
w1= 75-25= 50 m
A1= 150*50= 7500 m² smaller area with same perimeter
Answer:
84n-27
Step-by-step explanation:
-9(1-10n)-2(3n+9)
-9+90n-6n-18
-27+84n
We call the ratio between two directly proportional quantities the constant of proportionality. When these two quantities may increase or decrease, the constant proportionality always remains the same
