1. You times 2.5 by 10 (because there is 1 decimal point) which then equals 25/10.
2. Then you reduce 25/10 by 5, so it will be in simples form. And your answer is 5/2!
Hope this helped and Good Luck! :D
Answer:
y=1300-285x
Step-by-step explanation:
1300-575=725
725/5=145
y=1300-285x
We know that : Sum of Angles in a Triangle is equal to : 180°
⇒ In ΔRST, The Sum of Angles ∠R , ∠S , ∠T should be equal to 180°
⇒ m∠R + m∠S + m∠T = 180°
⇒ (2x + 10)° + (2x + 25)° + (x - 5)° = 180°
⇒ (2x + 2x + x) + (10° + 25° - 5°) = 180°
⇒ 5x + 30° = 180°
⇒ 5x = 180° - 30°
⇒ 5x = 150°
⇒ x = 30°
Answer: 15
Step-by-step explanation:
I am assuming the equation is set up like this:
(x+9)/3 = 8
Multipy by 3 to both sides
x + 9 = 24
Subtract 9
x = 15
