Step-by-step explanation:
cross multiply all equations seperately
1,n=63
2.n=24
3.n=19
4.n=20
Answer:a
☺️
5/9(F-32°) plug in 185
5/9(185°-32°)
5/9(153)
153×5=765
765/9=85
D.85°C
Answer:
x+7 oops x+15 ignore the first answer
x+11-8/-2
first do -8/-2=4
so it is x+11+4
11+4
x+15 is the answer
pls brainliest
7 = s²
s = x + 2
7 = (x + 2)²
7 = (x + 2)(x + 2)
7 = x² + 2x + 2x + 4
7 = x² + 4x + 4
x² + 4x = 3
