Answer:216 is your answer
Step-by-step explanation:
Answer:
x=20, g=100, f=80
Step-by-step explanation:
when ever somthing is suplementary it means the the answer will euqal to 180 degrees. That means your equation is going to be
3x+40+5x-20=180
8x+20=180
8x=160
x=20
Finding g
3(20)+40
60+40
g=100
FInding f
5(20)-20
100-20
f=80
Given:
y varies directly with x,
It is given that y = 7 when x = -9.
To find:
The value of y when x = 27 for the direct variation.
Solution:
It is given that y varies directly with x, so
...(i)
Where, k is the constant of proportionality.
It is given that y = 7 when x = -9. Putting these values in (i), we get
Putting 
in (i), we get
Putting 
, we get
Therefore, the required value is .
A) 20% of 449 = 89.8
B) 449 - 100 = 349
C) 449 - 75 = 374. 10% of 374 = 37.4. 374 = 336.6
D) 449 - 50 = 399. 20% of 399 = 79.8. 399 - 79.8 = 319.2
Hope this helps! :D
