4 0

Answer:

The cost of the bracelet was \$6

Step-by-step explanation:

Let

x------> amount of Carla's savings

y-----> the cost of bracelet

we know that

y=\frac{2}{5}x -----> equation A

1-\frac{2}{5}=\frac{3}{5}

so

9=\frac{3}{5}x ----> solve for x

x=9*5/3=\$15

substitute the value of x in the equation A and solve for y

y=\frac{2}{5}(15)=\$6

What is the solution for the equation 6x - 8 = 4x? x =
GarryVolchara [31]

Answer:

x = 4

Step-by-step explanation:

6x - 8 = 4x

<em>subtract 4x from both sides of the equation</em>

6x - 4x -8 = 4x - 4x

2x - 8 = 0

<em>add 8 to both sides of the equation</em>

2x - 8 + 8 = 0 + 8

2x = 8

<em>divide both sides of the equation by 2</em>

2x/2 = 8/2

x = 4
