Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
We will be using simultaneous equations to solve this problem.
Let's establish the two equations we will be using to solve the problem.
Let present age of father = f
Let present age of son = s
Equation No. 1 -
f = 3s
Equation No. 2 -
f + 15 = 2s
To begin with, we will substitute the value of ( f ) from the first equation into the second equation to solve for ( s ).
Equation No. 2 -
f + 15 = 2s
( 3s ) + 15 = 2s
3s - 2s = - 15
s = - 15
Next we will substitute the value of ( s ) from the second equation into the first equation to solve for ( f ).
Equation No. 1 -
f = 3s
f = 3 ( - 15 )
f = - 45
FINAL ANSWER:
Therefore, the present age of the father is - 45 years old.
It isn't possible for someone to be negative years old but this is the answer that I obtained from the equations.
Hope this helps! :)

Answer: Two equivalent ratios form a proportion. Equivalent ratios have the same value.
Cross multiply means this:
![(1.95)(x)=(10.0)(1)](https://tex.z-dn.net/?f=%281.95%29%28x%29%3D%2810.0%29%281%29)
Solving for x:
1.95 x = 10 divide both sides by 1.95
x = 10/1.95 =
5.128So you can buy
5.128 pounds of chocolate for 10.0$

the idea
In the given question the length and width of the plot are already given. although there is no direct specification regarding the one that is length or the one that is the width, so it can be taken as your own choice. This will not affect the ultimate answer.
So
Area of the rectangular plot = Length * Width
= 11.7 * 15.4 square cm
= 180.18 square cm
So the area of the rectangular plot as can be seen from the above deduction is 180.18 square centimeter.
Answer:
Each book cost $29.00
Step-by-step explanation:
$277-$16=$261.00
$261÷ 9= $29.00
Therefore each book costed $29.00
I hope this helps in any way.
