Y = - x + 4
x + 2 ( -x + 4 )=-8
x- 2 x + 8 = -8
- x = - 8 - 8
- x = - 16
x = 16
y = - 16 + 4
y = - 12
The system has one solution ( x, y ) = ( 16, - 12 ).

Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent. How many text messag

professor190 [17]

Given that Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent.

Kimora's cell phone bill for one month is $52.

We need to determine the number of text messages Kimora sent for one month.

Also, we need to write and equation and solve it.

The equation:

Let x denote the number of text messages Kimora sent for one month.

Thus, the equation is given by

$35+0.05x=52$

Therefore, the equation for the number of text messages Kimora sent for one month is $35+0.05x=52$

Solving the equation:

We need to solve the equation $35+0.05x=52$

Subtracting both sides of the equation by 35, we get;

$0.05x=17$

Dividing both sides of the equation by 0.05, we get;

$x=340$

Therefore, the number of messages sent is 340.

Norma Jean makes $25 per hour. She works 35 hours per week. She gets a commission of 15% on her total sales. How much should Nor

TEA [102]

Answer:

$24166.67

Step-by-step explanation:

$25 per hour and works 35 hours per week

Norma Jean makes 35 * 25 (without sales) = $875

Total commission made by Norma = 4500-875 = $3625

let total number of sales by Norma be x

15% is the same as 15/100

so (15/100) * x =3625 multiplying both sides by 100

15x = 362500 making x subject of formula

x = 362500/15

x = 24 166.67

Norma should sell total items worth $24166.67
