-7 ≤ x + 5 < 12
You really only need one of them i.e. x + 5 < 12
0 ≤ x + 12 < 19
0 ≤ x < 7
I realllllyy hope that is right for my own sake. Please let me know if i'm wrong and if so how I can do it right

Two equations needed : x + y = 223 and 5x + 2.5y = 765
Use the first equation, x + y = 223 and rearrange it to fit the problem and substitute : y = 223 - x
5x + 2.5(223 - x) = 765
5x + 557.5 - 2.5x = 765
2.5x + 557.5 = 765
2.5x = 765 - 557.5
2.5x = 207.5
2.5x ÷ 2.4 = 207.5 ÷ 2.5
x = 83
_______________________
Now just subtract 223 and 83 to get the others:
223 - 83 = 140
I guess this reads
You want to compute
By linearity of the definite integral,
Answer:
t = 5
Step-by-step explanation:
since those 2 angles make up 180 degrees turn it into an equation
20t + 5 + 15t = 180
combine like terms 20t + 15t = 35t
the equation is now 35t + 5 = 180
subtract 5 from both sides, 5 - 5=0, 180 - 5 = 175
35t = 175
now divide each side by 35, 35t/35 = t, 175/35= 5
t = 5
hope this helps :)
