The length of the granite must be less than 120 inches.
Step-by-step explanation:
Let x inches be the widht of the section. If the length is 3 times the width, then the length is 3x inches.
The perimeter of the rectangle is
Hence,
The perimeter of the section must be less than 320 inches, so
Answer:
-9
Step-by-step explanation:
If x varies directly with y, we can write an equation like: x = ky, where k is some constant. We want to solve for k first, so let's use the given numbers of y = 12 and x = 4:
x = ky
4 = 12k
k = 1/3
Now, our equation looks like this: x = (1/3)y. We want to find the value of y when x = -3, so plug -3 in for x:
x = (1/3)y
-3 = (1/3)y
y = -9
Thus, the answer is -9.
Hope this helps!
