Alisa is making bracelets with leather bands. each bracelet uses 7 3/4 inches of leather banding. she plans to make 4 bracelets.
Artyom0805 [142]
Each bracelet is 7 \frac{3}{4} inches

Turn it into an improper fraction 

Multiply 7 and 4 and add 3 which is over 4 which is \frac{31}{4}

Multiply by 4 | for each bracelet being made

\frac{31}{4} * \frac{4}{1}= \frac{124}{4}

124÷4=31

Answer:

You need 31 inches to make all the braclets

Which equations have infinitely many solutions?
igomit [66]

Answer:

4(x - 1) = 4x - 4

3x + 6 = 3(x + 2)

Step-by-step explanation:

The first equation is

5x - 1 = 5x + 1

We simplify to get;

- 1 = 1

This is not true, therefore this equation has no solution.

The second equation is

3x - 1 = 1 - 3x

Combine like terms:

3x + 3x = 1 + 1

6x = 2

x =  \frac{1}{3}

This has a unique solution.

The 3rd equation is

7x - 2 = 2x - 7

Group similar terms:

7x - 2x =  7 + 2 \\ 5x = 9 \\ x  =  \frac{9}{5}

The 4th equation is :

4(x - 1) = 4x - 4

4x - 4= 4x - 4 \\ x = x

This is always true. The equation has infinite solution.

The 5th equation is:

3x + 6 = 3(x + 2) \\ 3x + 6 = 3x + 6 \\ x = x

This also has infinite solution

The 6th equation is

3(x - 4) = 4(x - 3) \\ 3x - 12 = 4x - 12 \\ 3x - 4x =  - 12 + 12 \\ x = 0

It has a unique solution.
