The required value of x is 36

Step-by-step explanation :

Let the required number be x.

Three fourth of number = (3/4)x

One third of number = (1/3) x

According to the question ;

3x/4 = x/3 + 15

→ 3x/4-x/3 = 15

→ 9x - 4x / 12 = 15

→ 5x = 15 x 12

⇒ x = 180 / 5

⇒ x = 36

taurus [48]

Answer:

See below.

Step-by-step explanation:

$3+x=ax$ (Given)

$x=ax-3$ (Subtracted 3 on both sides)

$x-ax=-3$ (Subtracted ax on both sides)

$x(1-a)=-3$ (Factor out x from x - ax)

$x=-\frac{3}{1-a}$ (Divided 1 - a on both sides)

Bailey works at an athletic store. He earns $90 per day plus an 11% commission on his sales.

Ierofanga [76]

Step-by-step explanation:

Let the regular salary per day of Bailey be $s_{r}$

Let the salary through commission be $s_{c}$

Let the sales on a day be $sales$

It is given that $total$ = $s_{r}+s_{c}$

It is given that $s_{r}=90$

It is given that $s_{c}=11$ % of $sales$

So, $s_{c}=\frac{11}{100}\times 500=55$

So, $total=s_{c}+s_{r}=55+90=145$

Hence,Bailey earns $ $145$ on thursday.
