yan [13]

Answer:

Halloween question, perfect timing! Your answer would be 2 pounds per friend.

Step-by-step explanation:

Here's how we get this:

First, multiply 3/4 by 6. You'll get 4.5. Let's use a decimal for this equation.

Now, you'll divide 9 by 4.5, to get 2. There's our answer. But we want to double-check and see if it's right.

We can do that by multiplying 4.5 by 2, or 2 by 4.5.

4.5 x 2 = 9

Therefore, your answer is 2 pounds per friend.

Hope I helped! ☺

Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.

Tanya [424]

Answer:

16 = 3x

Step-by-step explanation

Find the diagram attached.

Perimeter = sum of all its sides

Sum of all its sides= x+x+x

Sum of all its sides = 3x

Given perimeter = 16in

Equating both;

3x = 16

x = 16/3

x = 5.33in

Hence the value of x is 5.33 and the required equation is 16 =3x
