The relationship between fractions and decimals is that with a fraction you are dividing whereas a decimal is treated like a number.
i.e. 1/4=0.25
Think of decimals as 100 being the whole or 1 so split 100 into 4 and you get 25 or 0.25

Answer:
$ 8300 (Approximately)
Step-by-step explanation:
Given:
Initial price of the trailer is, 
Rate of decrease per year is, 
The time in years is, 
The exponential expression for the decrease in price after 't' years is given as:
Plug in all the given values and solve for 'P'. This gives,
Rounding it to the nearest whole number, the price of the travel trailer after 5 years is $ 8,300.
First we need to find how far away the base of the ladder is from what it is leaning against. The ramp is the hypotenuse and the height from the ground in a leg. Let’s use Pythagorean’s theorem.
a^2 + b^2 = c^2
Substitute
a^2 + (5)^2 = (20)^2
Solve for a^2
a^2 = (20)^2 - (5)^2
Solve for a
a = 5 √15
The slope will be rise over run
5/5 √15 = √15/15 or 0.258…
Assume the old of Jack is X and the old of Lacy is Y
so ...
do the mathematical model ...
.
X=2Y
(X+7)+(Y+7)= 35
-
THEN
Solve the equation
y= 7
x = 14
