$34.99 ... 2.5-pound bags
$x = ? ... 1 pound
If you would like to know what is the unit rate of the shrimp in dollars per pound, you can calculate this using the following steps:
34.99 * 1 = x * 2.5
34.99 = x * 2.5 /2.5
x = 34.99 / 2.5
x = $13.996 = $14
The correct result would be $14.
Contradictions usually mean they go against established rules. Squaring a negative number is one example if it is in math. But just think of anything that goes against what is known.
Answer: x = -1 and y = -2
Step-by-step explanation:
So if you know y = x-1 you can plug that in where y is in the first equation
-4x + 3(x-1) = -2
Distribute the 3:
-4x +3x -3 = -2
Combine like terms:
-x -3 = -2
Add 3 to both sides:
-x = 1
Multiply by -1:
X = -1
Then you plug that into the other equation to get y=(-1)-1
Which is -2
