*NOT MY WORK ITS FROM SOMEONE ELSE WHO ASKED THE SAME PROBLEM*
Answer: x=15, y= 10
Step-by-step explanation:
Answer: x=15, y=10
*Note: x and y are only variables used to solve this problem, but know that the two numbers are 15 and 10.
Step-by-step explanation:
For this problem, we can use system of equations. Let's use x for one number and y for the other.
First Equation:
x+y=25
We get this equation because it states that the sum of the two numbers is 25.
Second Equation:
y=x-5
We get this equation because it says one number (y) is 5 less than the other (x).
Since we have two equations, we can use substitution method to solve.
[distribute 1 to (x-5)]
[combine like terms]
[add both sides by 5]
[divide both sides by 2]
Now that we have x, we can plug it into any of the equations to find y.
[plug in x=15]
[subtract both sides by 15]
Finally, we have our answer, x=15 and y=10.
Answer:
Tienes 30 años, ya que cuando tendras el doble de la edad de 10 años, o sea 20 años y dentro de 10 años da igual a 30 años.
Espero que ayude
Let's work on the triangle first. The x intercept of 2y=27-3x is
0 = 27 - 3x
3x = 27
x = 9
So A(9,0)
B is the meet of 2y=27-3x and y=3x
2y=27-y
3y=27
y=9
y is the height of OAB; we don't really need x
Area(OAB) = 
Now we have to subtract
Area = 40.5 - 24.3 = 16.2
Answer: 16.2
