X represent the number of laps Marcy swam, 114x represent the number of times Toni swam.
20 + 0.80(114x) + 15 + 0.85x = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x + 35 = 257
Required equation is 92.05x + 35 = 257
I believe it would be the last answer, 6.25
if this is correct i’m very sorry, but if this helps, please mark brainliest. :)
Answer: 0.025
Step-by-step explanation: we reject null hypothesis if p<0.05
7*y - 5*(4-2y) = 7y - 20 +10y = 17y-20 = 31,
y =3, x = -2.
Weird 20 min without answer!
