5x + 15y = 1200. x. | y
___________
105 | 45
30. | 100
60. | 60
5(x) + 15y = 1200. 5(x) + 15y = 1200. 5(x) + 15y = 1200.
5(x) + 15(45) = 1200. 5(30) + 15y = 1200. 5(x) + 15(60) = 1200
5x + 675= 1200. 150 + 15y = 1200. 5x + 900 = 1200
5x = 1200 - 675 15y = 1200 - 150. 5x = 1200-900
5x = 525 15y = 1050. 5x = 300
x= 525÷5. y= 1050÷15. x = 300÷5
x= 105. y = 100 x = 60
The answer remains as is, or you could do it this way: 1(9 + 8b²).
Answer:
No, because 32 is not a whole number power of -2. (The answer would be 'yes' for -32, but not for +32).

Step-by-step explanation:
Are the inequalities x > 3 and 3 < x equivalent?
They both say that x must be larger than 3. No bickering here. So yep, they're equivalent.
Inequalities usually have a lot of solutions—in fact, infinitely many. Think about the inequality x > 3. This inequality states that "x must be larger than 3." Any number bigger than 3 is a solution to this inequality. That includes 3.001, 3.0001, 4, 5, 2 million, and every other number bigger than 3. We don't have time at the moment to name them all,
