Answer:
it's 4
Step-by-step explanation:
We are given expression for cost of admission at an amusement park : 15a+12c.
Where a is the number of adults and
c is the number of children.
We need to find the total cost of 5 adults and for 10 children.
<em>In order to find the total cost of 5 adults and for 10 children, we need to plug a=5 and c=10 in 15a+12c expression.</em>
Plugging a=5 and c=10 in 15a+12c expression, we get
15(5) + 12(10) = 75 + 120 = $195.
<h3>Therefore, the total cost for 5 adults and for 10 children is $195.</h3>
Answer:
B. 21.1 yd
Step-by-step explanation:
The perimeter of the figure is the sum of all its three sides.
Take note that the dotted line is not a side length of the figure.
The side lengths are 9 yd, 5 yd, and 7.1 yd.
Therefore, the perimeter of the figure = 9 + 5 + 7.1
Perimeter = 21.1 yd.
Also, take note of the unit of the perimeter. Unit of the perimeter would not be squared. Only area has a unit that is squarred.
It is convenient to start with the 2-point form of the equation for a line.
... y - y1 = (y2 - y1)/(x2 - x1)×(x - x1)
Either point can be (x1, y1), and the other can be (x2, y2). If we take them in order, we get
... y - 4 = (16 - 4)/(5 - 3)×(x - 3) . . . . . fill in the two points
... y = 12/2(x -3) +4 . . . . . . . . . . . . . . add 4, simpliffy a bit
... y = 6x -18 +4 . . . . . . . . . . . . . . . . . eliminate parentheses
... y = 6x -14 . . . . . . . . . . . . . . . . . . . . put in slope-intercept form
