Adult tickets + kids tickets = 120$
Y represents kids tickets
Z represents adult tickets
Z = twice kids tickets = 2Y
In ecuation:
Z + Y = 120$
Replace Z with 2Y
2Y + Y = 120 $
3Y= 120 / divided by 3
Y = 40$
You know the cost for 1 kid ticket
40 : 4 = 10 kids tickets sold
Z = 2x 40= 80$ for adult tickets
80:8 = 10 adult tickets sold
If u are looking for area just multiply 150 by 400 but if you are finding perimeter just do 150 plus 150 plus 400 plus 400
Answer:
The equation is;
y = -1/4x + 607.5
Step-by-step explanation:
Let us have the number of drops as y axis while the number of minutes is x axis
The points to use are;
(30,600) and (130,575)
The slope can be calculated using;
m = (y2-y1)/(x2-x1)
= (575-600)/(130-30) = -25/100 = -1/4
So the equation as we model using the normal equation of a straight line (y = mx + c, m is slope and c is the intercept)
y = -1/4x + c
To get c, we simply substitute one point
Let us use (30,600)
We have
600 = -1/4(30) + c
600 + 7.5 = c
c = 607.5
So the equation is ;
y = -1/4x + 607.5
Answer:
v = 55
Step-by-step explanation:
Plug in the values provided into the equation
v = u + at
v = 23 + 8 * 4
Solve
v = 23 + 8 * 4
v = 23 + 32
<u>v = 55</u>
