Answer:
Y-12 + y =120 take 12 to the other side get 2 y = 132
Y=66 so y-12=x
X=54
4 23/40
Explanation:
972 u³
Step-by-step explanation:
The radius is 9 . We can use formula ,
⇒ V = 4/3 π r³
⇒ V = 4/3 × π × 9³
⇒ V = 4 × π × 81 × 3
⇒ V = 972 unit³
3x + 1/5y = 7
1/5y = 7 - 3x
y = 5 (7 - 3x)
y = 35 - 15x
Answer:101°
79 + 101=180
