(3.10/3.35)-1*-1=0.07462686567
So the percantage decrease to the nearest tenth is 7.4%
3.35 x 0.07462686567= .25

Step-by-step explanation:
If the point is at (-3, -4), it is located in the third quadrant. You can find the tangent of an angle by finding the ratio of the length of the opposite side to the length of the adjacent side. In this case, the opposite side of the angle is the vertical line with a length of 4 units, while the adjacent side of the angle is the horizontal line with a length of 3 units. <em>Thus, tan θ = 4/3.</em>
X represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.
20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257
Required equation is 1.85x + 35 = 257
