The answer is C,
Coterminal when involving angles is an angle that is 360 degrees greater or lesser. In order to find whether something is coterminal or not you take one of your angles and subtract or add 360 from it until you reach that number. If you add/sub 360 and you can't ever equal the other number than they are not coterminal.
Example:
591 - 360 = 231
So that means
231 degrees = 591 degrees
Example 2:
51 - 360 = 309
51 + 360 = 411
411 + 360 = 771
771, 411, and 309 /= 591 or 231
So 51 degrees /= 231 or 591
C: 51 is not coterminal!

Answer:
1. x = 5 2. y = 4 3. x = -2
Step-by-step explanation:
2x - y = 9 -5x + 2y = 13 3x + 4y = -6
<u>4x + y = 21</u> <u>5x + y = -1 </u> <u> 7x(-1) + 4y(-1) = -14(-1)</u> <(multiply all by -1)
<u>6x = 30 </u> <u>3y = 12</u> <u> -4x = 8</u>
6 6 3 3 4 4
x = 5 y = 4 x = -2

Answer:
300 Kilo-meters
Step-by-step explanation:
Since 4 / 5 of a liter runs for 12 kilo-meters and you need to find how much 20 liters would run, you need to find how much a liter can run for.
L is the variable for which how much a liter can run for. Which is what we need to solve.
4 / 5 x L = 12
To isolate L, you need to multiply both sides by 5/4 since multiplying a number by its reciprocal produces one. Note: A reciprocal is a number where the denominator and numerator are switched. Example: 2/3 and 3/2 multiplying it with each other get 6/6 which is 1.
4 / 5 x 5 / 4 x L = 12 x 5 / 4
L = 12 x 5 / 4
L = 60/4
L = 15
Now you know that each liter is worth 15 kilo-meters and you need to find how much 20 liters will run for.
20 x L = Kilo's Ran
20 x 15 = Kilo's Ran
300 = Kilo's Ran
20 Liters will run for 300 Kilo-meters.
