If you would like to solve 2x + 5y = -13 and 3x - 4y = -8, you can do this using the following steps:
2x + 5y = -13 /*4
3x - 4y = -8 /*5
_______________
8x + 20y = -52
15x - 20y = -40
_______________
8x + 15x + 20y - 20y = -52 - 40
23x = -92
x = -92 / 23
x = -4
<span>3x - 4y = -8
</span>3 * (-4) - 4y = -8
-12 - 4y = -8
12 + 4y = 8
4y = 8 -12
4y = -4
y = -1
The correct result would be x = -4 and y = -1.

12000 g would be equal to 12 kg not 1.2 kg so the answer has to be A) greater than.
Answer: A) GREATER THAN
Answer:
122
Step-by-step explanation:
12 times 2 times 5 plus 2 gets rewritten as
(12)(2)(5) + 2
Follow PEMDAS and do multiplication first. From left to right...
24(5) + 2 { (12)(2) = 24 }
120 + 2 { (24)(5) = 120 }
122 { 120 + 2 = 122 }
