Well it would make sense that Jenny had 6 marshmallows and Julie did not put any in, Hope this helped a little
Answer:
Step-by-step explanation:
1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.
2) If you meant X^2+12x=40:
a) Take half of the coefficient of x: that would be (1/2)(12), or 6.
b) Square this result, obtaining: 6² = 36
c) Add this 36 to x^2 + 12x + 40, and then subtract it: We get:
x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76
We have to add 36, as indicated above, to "complete the square."
Answer: Your answer is 36 percent.
Step-by-step explanation:
You divide 9 carrot muffins by the total which is 25, then you get 0.36 then, you multiply that by 100.
Number of general admission tickets sold is 75
<u>Step-by-step explanation:</u>
Step 1:
Let the number of general admission tickets be x, then the number of student ID tickets = 200 - x. Total cost of tickets sold = $625
Cost of general admission tickets = 5x
Cost of student ID tickets = 2(200 - x) = 400 - 2x
Total cost of tickets = 5x + 400 - 2x = 625
⇒ 3x + 400 = 625
⇒ 3x = 225
⇒ x = 75
