Answer: 15
Step-by-step explanation:
1/3x - 2 = 3
1/3x = 5
x = 15
Answer:

Step-by-step explanation:
$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total
$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

Answer:
Area of triangle is 25.
Step-by-step explanation:
We have been given an isosceles right triangle
Isosceles triangle is the triangle having two sides equal.
Figure is shown in attachment
By Pythagoras theorem

AD is altitude which divides the triangle into two parts
DC=5 implies BC =10 since D equally divides BC
Let AC=a implies AB=a being Isosceles
On substituting the values in the Pythagoras theorem:




WE can find area of right triangle by considering height AB and AD
Area of triangle ABC is:
(1)

And other method of area of triangle is:
(2)
Equating (1) and (2) we get:



Using area of triangle is: 
Now, the area of triangle ABC=

Both together cost $1759.
That means that sum of the two prices is $1759.
The operation that is the opposite of addition is subtraction.
We subtract $469 from $1759 to find the price of the televition.
$1759 - $469 =
1759
- 469
-----------
1290
$1759 - $469 = $1290
Answer: The price of the television is $1290.
