What is the value of x?<br>45°<br>( 2x-5)°​
AlekseyPX

(2x - 5)° + 45° = 180°

2x° + (-5 + 45)° = 180°

2x° + 40° = 180°

2x° = 180° - 40°

2x° = 140°

x° = 140 ÷ 2

x° = <u>7</u><u>0</u><u>°</u>

So, the value of x is 70°

Arlene buys a phone case and charging cord for 15% off. The original cost of the phone case is $18. Her total discount is $4.20.
mel-nik [20]

Answer: $10

Step-by-step explanation:

Assume the price of the phone case is x.

Assume the price of the charging cord is y.

Discounted price for phone case :  15% * x

= 0.15x

Discounted price for charging cord = 0.15y

Expression is therefore:

0.15x + 0.15y = 4.20

0.15 * 18 + 0.15y = 4.20

2.7 + 0.15y = 4.20

0.15y = 4.2 - 2.7

y = 1.5/0.15

y = $10
