Answer:
The Answer is that Orchestra seats were $15 and Balcony seats were $9.
Step-by-step explanation:
400(x+6) + 250x = 8250
400x + 2400 + 250x = 8250
650x + 2400 = 8250
650x = 5850
x = 9
Proof:
400(15) + 250(9) = 8250
6000 + 2250 = $8,250
Answer:
x = 5
Step-by-step explanation:
You want to find x such that ...
x^2 +(x +1)^2 = 61
2x^2 +2x -60 = 0 . . . . . simplify, subtract 61
x^2 +x -30 = 0 . . . . . . . divide by 2
(x +6)(x -5) = 0 . . . . . . . . factor; solutions will make the factors be zero.
The relevant solution is x = 5.
Answer: Since 3−5+2=0, then 2
is the additive inverse of 3−5 is 2
Since 5−3−2=0, then −2is the additive inverse of 5−3. is -2
Step-by-step explanation: additive inverse
The additive inverse of any number
x
is the number that gives zero when added to
x
. Example: the additive inverse of
5 is −5.
