Answer:

D.

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

P=2(\text{width + length})

Hence,

P=2(x+3x)=2\cdot 4x=8x

The perimeter of the section must be less than 320 inches, so

8x

Hey there!

“6 + r = 8”

• FIRST: FIRST THE EQUATION

r + 6 = 8

• SECOND: SUBTRACT by 6 on BOTH SIDES

r + 6 – 6 = 8 – 6

CANCEL out; 6 – 6 because that gives you 0

KEEP: 8 – 6 because that helps solve for your r-value

• THIRD: SOLVE FOR YOUR EQUATION

8 – 6 = r

• FOURTH: ANSWER THE QUESTION

8 – 6 = 2

FIFTH: ANSWER

r = 2 ☑️

Good luck on your assignment and enjoy your day!

What would be the answer for 24y =7
Marta_Voda [28]

Answer:

y=\frac{7}{24}

Step-by-step explanation:

24y = 7

Our primary objective here is to get y on it's own side, without any numbers attached.

Since a 24 is attached to the y, we have to divide the 24y by 24.

24y=7

\frac{24y}{24} = \frac{7}{24}

Remember that whatever we do to one side, we MUST do to the other.

y=\frac{7}{24}

Since \frac{7}{24} can't be simplified, that would be our answer.

Please let me know if you need help with anything else. :)
