Answer:
12 white 28 printed
Step-by-step explanation:
x = white y = printed
x + y = 40————(1)
4.95x + 7.95y = 282————(2)
Solve for x using 1st equation
x = 40 - y Plug in for x using 2nd equation
4.95(40 - y) + 7.95y = 282 Solve for y
198 - 4.95y + 7.95y = 282
3y = 84
y = 28 Plug in for y using 1st equation
x + (28) = 40 Solve for x
x = 12
I hope this helped and please mark me as brainliest!
The increase from 5 to 8 was by 60%.
Use the Sine Rule:-
b / sin B = c / sin C
15 / si n B = 9 / sin 29
sin B = 15* sin 29 / 9 = 0.8080
B = 53.90 degrees
