Answer:
194 and 66
Step-by-step explanation:
Represent the numbers by a and b.
Then a + b = 260 and a = 3b - 4.
Substitute 3b - 4 for a in the first equation. Then:
3b - 4 + b = 260, and:
4b = 264, which works out to b = 66. If b = 66, then a = 3(66) - 4 = 194.
The two numbers are 194 and 66.
It's not factored with rational numbers the polynomial is not factorable with rational numbers
Step-by-step explanation:
The three methods most commonly used to solve systems of equations are substitution , and augmented matrices.
$200 + 15% ($2500-1000) =
$200 + 15% ($1500) =
$200 + $225=
$425
