let nwmber to be X
the number is 12 less than it's square,
so X=12-X^2
=> X^2+X-12=0
=> (X+4)(X-3)=0
=>X= 3, or X=-4
in math we don't usually take negative numbers into account so your number would be 3
Answer:
It would take 3.6 mins.
Step-by-step explanation:
In order to find this, we simply divide the amount of time by the amount of the tank that is filled.
2 ÷ 5/9 = 3.6
<span>the answer
The triangle congruence says triangle ERT is congruent to triangle CTR. </span>
For the first system, we have
1 - 3x + 3y = -8
or
-3x + 3y = -9
The second equation, however, tells us
-3x + 3y = 13
but -9 ≠ 13, so this system has no solution.
For the second system, notice that multiplying both sides of
4x - 8y = 6
by 1/2 gives
2x - 4y = 3
which is identical to the other equation in the system. Then all point (x, y) that lie on this line are solutions to the system, meaning there are infinitely many solutions.
