Hi again :)
5(y + 1) = 30
Once again, use the distributive property
(5)(y) + (5)(1) = 30
5y + 5 = 30
Add -5 to both sides
5y + 5 - 5 = 30 - 5
5y = 25
Divide both sides by 5
5y/5 = 25/5
y = 5
Best of luck!
210 because 209 is closer to 210 than to 200
Answer: 35 degrees
Step-by-step explanation:
A triangle always adds up to 180 degrees
? + 125 + 20 = 180
? + 145 = 180
? = 35
Answer:
√15/3
Step-by-step explanation:
x² - y² =√5
(x +y)*(x -y) = √5
(x +y) * √3 = √5
x+y = √5 / √3
x +y = √5*√3 / √3*√3
x +y = √15/3
