Samantha has 54 beads. Amanda has twice as many beads as Samantha. They are making bracelets it takes 8 beads to make a bracelet
wlad13 [49]

Answer:

On combining the beads they can make 20 bracelets.

Step-by-step explanation:

The number of beads Samantha has  =  54 beads

Number of beads Amanda has = 2 x( Number of beads Samantha has)

=  2  x 54  =  108 beads

The total number of beads Amanda and Samantha has  

=   54 beads + 108 beads

= 162 beads

Number of beads required to make 1 bracelet  =  8 beads

Now, \textrm{The number of bracelets made}  = \frac{\textrm{Total number of beads they both have}}{\textrm{Beads required to make 1 bracelet}}

=\frac{162}{8}  = 20.25≈  20

or, the total number of bracelets they can make is 20.

Hence, on combining the beads they can make 20 bracelets .

Eighty, decreased by three times a
Marina86 [1]

Answer:

The number is 9.

Step-by-step explanation:

Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.

80 - 3x = 5x + 8

First, let's add 3x to both sides.

80 - 3x + 3x = 5x + 3x + 8

80 = 8x + 8

Next, let's subtract 8 from both sides.

80 - 8 = 8x + 8 - 8

72 = 8x

Finally, let's divide both sides by 8.

72/8 = 8x/8

9 = x

<em>"x" is 9.</em>

<em>So the secret number is 9.</em>

P.S.

This is my first answer to a Brainly question so please don't complain!
