A meal plan lets students buy $20 meal cards. Each meal card lasts about 8 days. write and graph equation

Luda [366]

Step-by-step explanation:

Given that,

A meal plan lets students buy $20 meal cards.

Each meal card lasts about 8 days.

Let us assume that y denotes number of days for a 20 dollar meal card i.e. $20 every 8 days.

Let x = number of $ for another day.

So,

$y=\dfrac{8}{20}x+8$

$y=\dfrac{2}{5}x+8$

Hence, this is the required equation.

Nicole’s friend runs 3/8 of a mile, but her distance is only 3/5 of Nicole’s distance. How far does Nicole run?

salantis [7]

Step-by-step explanation:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Let distance travelled by Nichol =x

${:}\longrightarrow$ $\sf {\dfrac {3}{5}}\times x={\dfrac {3}{8}}$

${:}\longrightarrow$ $\sf {\dfrac {3x}{5}}={\dfrac {3}{8}}$

${:}\longrightarrow$ $\sf 8 (3x)=5×3$

${:}\longrightarrow$ $\sf 24x=15$

${:}\longrightarrow$ $\sf x={\dfrac{24}{15}}$

${:}\longrightarrow$ $\sf x=1.6$

$\therefore$ Nichol runs 1.6miles .
