Solve for x: 1/5 (5x + 12) = 18
DENIUS [597]
Solution for 1/5(5x+12)=18 equation:
<span>x in (-oo:+oo)

(1/5)*(5*x+12) = 18 // - 18

(1/5)*(5*x+12)-18 = 0

1/5*(5*x+12)-18 = 0

1/5*(5*x+12)-18 = 0

x-78/5 = 0

x-78/5 = 0

x-78/5 = 0 // + 78/5

x = 78/5

x = 78/5

Angle 1 and angle 5 are equal so you can set the equations equal to each other. 60 - 2x = 70 - 4x 
60 + 2x = 70
2x = 10
x= 5

In 1928, when the high jump was first introduced as a women's sport at the Olympic Games, the winning jump for women was 70.0 in
sveta [45]

Answer: year 2194



Explanation:



1) Model the jump of the women:


i) initial jump = 70.0 in


ii) increase rate = 0.48% per year


iii) equation: h = 70.0(1 +0.0048)ⁿ


2) Model the jump of the men:


i) initial jump 86.5 inches.


ii) increase rate, 0.4%.


iii) equation: h = 86.5 (1 + 0.004)ⁿ


3) Equal the two equations (h = h) to find when the jumps will be equal:


i) 70.0(1 +0.0048)ⁿ = 86.5 (1 + 0.004)ⁿ


ii) 70.0(1.0048)ⁿ = 86.5 (1.004)ⁿ


ii) [1.0048ⁿ / 1.004ⁿ] = 86.5/70.0


iii) [1.0048/ 1.0040]ⁿ = 86.5/70.0


iv) n log (1.0048 / 1.0040) = log ( 86.5/70)


v) n = log (86.5/70) / log (1.0048/1.0040) ≈ 266


3) year = 1928 + 266 = 2194


That is in the year 2194
