In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
Answer:
4V = 3U
Step-by-step explanation:
The final cost of a sale item is determined by multiplying the price on the tag by 75%.
Let us assume that the final cost of the sale item is V and the price on the tag is given by U.
Then the equation that best describes the function that represents the situation is
⇒ 4V = 3U (Answer)
The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y = ax 2 + bx + c, the axis of symmetry is a vertical line.
Answer: 7.3
Step-by-step explanation:
Do the parentheses first!
4-7= -3
Then, multiply -3 by 2
-3×2= -6
Next,
-6-6.7= -12.7
Then, add -12.7 to 20
-12.7+20=7.3
Your answer is 7.3
