in short, we simply split the total amount by the given ratio, so we'll split or divide 1020 by (15 + 2) and then distribute accordingly.

Answer:
x² + x - 12 = 0
Step-by-step explanation:
If x = -4 and x = 3 are solutions to a quadratic equation, then
(x + 4)(x - 3) = 0
Expand the brackets: x² - 3x + 4x - 12 = 0
Combine like terms: x² + x - 12 = 0
The painting's original price was $3,500.
Step-by-step explanation:
Step 1:
The price now is $500 lesser than 3 times the original price. So
The current selling price = (3 × original price) - $500.
If the current selling price is y and the original price is x, then

Step 2:
For this question, we have
. Substituting this in the equation, we get

So the original price of the classic painting was $3,500.
Answer:
Write the number 12489 in words
To do this problem:
-5y + 8 = -3y + 10 (add 3y to both sides)
-2y + 8 = 10 (subtract 8 from both sides)
-2y = 2 (divide by -2)
y = -1
