Pilar and Ramesh left a 20% tip after

having dinner. The amount of the tip

was $5. Pilar's dinner cost $15. Which

equation can you use to find x, the

cost of Ramesh's dinner?

A 0.2(x + 15) = 5 odnosu po

B 20x + 15 = 5

C 2x + 15 = 5

A 0.2(x + 15) = 5

Step-by-step explanation:

Let x represent the cost of Ramesh's dinner.

Since, Pilar's dinner cost $15.

The sum of pilar and Ramesh's dinner is;

= 15 + x

And also, since the tip is 20% of the cost of their dinner;

tip = 20% of (15+x) = 0.20(15+x)

The amount of the tip is equal to $5

0.20(15+x) = 5

Which gives;

0.2(x+15) = 5

Solving the equation, we have;

x+15 = 5/0.2

x+15 = 25

x = 25-15

x = $10

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
