5(4x-5y)-2=453
5(4x-5y)=455
4x-5y=91
When solving for x
4x=5y+91
x= 5y+91/4
When solving for y
-5y=-4x+91
y=-4x+91/-5

Answer:
3.50*3=10.5
the total will be $10.50
Step-by-step explanation:
Answer:
x = 135°
Step-by-step explanation:
6 sided polygon = hexagon
The sum of the interior angles of a hexagon = 720°
⇒ 4x + 90 + 90 = 720
⇒ 4x = 720 - 90 - 90
⇒ 4x = 540
⇒ x = 540 ÷ 4
⇒ x = 135°
Yes. They are both right.
Nice computer my dear sir
