Answer:
t = 5.8
Step-by-step explanation:
Using the SINE rule:
t/sin(23) = 14/sin(108)
Therefore t = 14 / sin(108) * sin(23)
Therefore t = 5.7517463
or 5.8 to the nearest tenth.
Answer:
0.79 x + 4.5 equal to or less than 34.25
0.79 x + 4.5 = 34.25
0.79 x = 29.75
x = 37.6582278
37 wings
15.99 + .79 x = 75
.79 x = 59.01
x = 74.6962025
74 songs
6.50 + 2.25 x = 48
2.25 x = 41.5
x = 18.4444444
18 rides
7 x - 18.65 = 175
7 x = 193.65
x = 27.6642857
28 cars
12 + 32 + 6x = 80
44 + 6x = 80
6x = 36
x = 6 guppies
hope this helped :)
