The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators answers is: False
Answer:
34
Step-by-step explanation:
40.8 ÷ 1.2 = 34
Use the geometric mean involving altitudes. That will be
. Filling in our values for the legs of that triangle our proportion then looks like this:
. Cross multiply to get
. Taking the principle value of that square root, we get that x = 12.
Answer:
<h2>
y = (5/2)x + 5/2</h2>
Step-by-step explanation:
The coordinates of the given x-intercept are (-1, 0).
As we move to the right from (-1, 0) to (2. 7.5), x increases by 3 and y by 7.5.
Thus, the slope of this line is m = rise / run = 7.5 / 3, or 75 / 30, or 5/2.
Thus, starting from y = mx + b, we have:
7.5 = (5/2)(2) + b, or
7.5 = 5 + b
Thus, b = 2.5, and the equation is
y = (5/2)x + 5/2
check: Is 7.5 = (5/2)(2) + 5/2 true?
Is 7.5 = 5 + 5/2 true? YES
Let
x = number of tickets
y = cost
For each row, divide the cost over the number of tickets
Row one: y/x = 3/2 = 1.5
Row two: y/x = 6/4 = 1.5
Row three: y/x = 9/6 = 1.5
Row four: y/x = 12/8 = 1.5
Row five: y/x = 15/10 = 1.5
The constant of proportionality is 1.5
This means each ticket costs $1.50
