Answer:
Ray = 19 yrs old
Tom = 25 yrs old
John = 57 yrs old
Explanation:
Let x be the years of Tom
R = x - 6
J = 3R = 3(x - 6)
T = x
R + J + T = 101
x - 6 + 3(x - 6) + x = 101
2x - 6 + 3x - 18 = 101
5x - 24 = 101
5x = 125
x = 125/5 = 25
R = 25 - 6 = 19
J = 3(25 - 6) = 57
T = 25
2,800-3,200
Explanation: multiply 35 and 40 by 80 since those are the variables
Answer:
3/4
Step-by-step explanation:
Δy = y1 - y2 = 1 - (-2) = 3
Δx = x1 - x2 = -3 - (-7) = 4
Slope = Δy/Δx = 3/4
Answer:
−7/18
