So, let's say the soft drink equals y and the sandwich equals x.
x + y = 9.9
The sandwich costs 3.5 times as much as the soft drink
x = 3.5y
Therefore, we can replace x with 3.5y since they're the same thing
3.5y + y = 9.9 <-- That's the equation :)
Formula for perimeter a+b+a+b

2.20 rounded to the nearest tenth is 2.2 it is already rounded if it was 2.29 it would be 2.3
Answer:
34
Step-by-step explanation:
-5y=-45
y=-45/-5
=9
y=9
then
5y-11=5×9-11
=45-11
=34
Answer:
6 feet
Step-by-step explanation:
cos = adj/hyp
cos76 = adj/24
multiply both sides by 24
24 * cos76 = adj
5.806125494392025 = adj
Rounded
6 feet
