Answer:

$1,444.45

Step-by-step explanation:

EV= 100(0.44444444444)+300(0.22222222222)+400(0.22222222222)+800(0.11111111111)

EV= $288.89

288.89*5= $1,444.45

By knowing the <em>blood</em> pressure and applying the <em>quadratic</em> formula, the age of a man whose normal <em>blood</em> pressure is 129 mm Hg is 40 years old.

<h3>How to use quadratic equations to determine the age of a man in terms of blood pressure</h3>

In this problem we have a <em>quadratic</em> function that models the <em>blood</em> pressure as a function of age. As the latter is known, we must use the quadratic formula to determine the former:

129 = 0.006 · A² - 0.02 ·A + 120

0.006 · A² - 0.02 · A - 9 = 0

A = \frac{0.02 \pm \sqrt{0.006^{2}-4\cdot (0.006)\cdot (- 9)}}{2\cdot (0.006)}

A = 1.667 + 38.733

A = 40

By knowing the <em>blood</em> pressure and applying the <em>quadratic</em> formula, the age of a man whose normal <em>blood</em> pressure is 129 mm Hg is 40 years old.

Let's solve your equation step-by-step.
AleksAgata [21]
3 - (5x + 4/5) = x/2
3 - 5x - 4/5 = x/2
3 - 4/5 = x/2 + 5x
15/5 - 4/5 = x/2 + 5x
11/5 = x/2 + 5x.....multiply both sides by 10
22 = 5x + 50x
22 = 55x
22/55 = x
2/5 = x
