The lengths of two sides of a triangle are 10 and 24, and the third side is x. How many whole number values are possible for x.

.

Step-by-step explanation:

In any triangle, the sum of the lengths of any two sides should be strictly greater than the length of the third side. For example, if the length of the three sides are , , and :

,

, and

.

In this question, the length of the sides are , , and . The length of these sides should satisfty the following inequalities:

,

, and

.

Since , the inequality is guarenteed to be satisfied.

Simplify to obtain the inequality .

Similarly, simplify to obtain the inequality .

Since needs to be a whole number, the greatest that satisfies would be . Similarly, the least that satisfies would be . Thus, could be any whole number between and (inclusive.)

There are a total of distinct whole numbers between and (inclusive.) Thus, the number of possible whole number values for would be .

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image
