Jessica had m beads. She used 18 of them to make a necklace for her mom. Then she used the rest to make k bracelets for her frie

Y_Kistochka [10]

The expression to represent this would be (m-18)/k.

We first subtract the 18 beads she used in her mother's bracelet from her beginning number, m. We then divide our result by k, the number of bracelets she made for her friends.

Does anyone know the surface area for this problem. if so i will mark brainliest.

From the given volume, we know that the ratio is:
$\text {Ratio of yellow eraser to white eraser = } \sqrt[3]{ \dfrac{16}{2} }$

From the given area, we know that the ratio is:
$\text {Ratio of yellow eraser to white eraser = } \sqrt{ \dfrac{52}{x} }$

Equate the two ratio and solve for x:
$\sqrt[3]{ \dfrac{16}{2} } = \sqrt{ \dfrac{52}{x} }$

Cube both sides:
$\dfrac{16}{2} = \bigg(\sqrt{ \dfrac{52}{x} }\bigg)^3$

Square both sides:
$\bigg(\dfrac{16}{2} \bigg)^2 = \bigg( \dfrac{52}{x} }\bigg)^3$

Simplify each term:
$\dfrac{16^2}{2^2} = \dfrac{52^3}{x^3}$

Cross multiply:
$256x^3 = 562432$

Divide both sides by 256:
$x^3 = 2197$

Cube root both sides:
$x = 13$
