The answer would be -8/27 I believe
Answer:
15
Step-by-step explanation:
Let the number of adult tickets be x while children ticket be y. Since the total tickets were 20 then we can form the equation
x+y=20
Making x the subject then x=20-y
Considering the cost of each ticket
15x+10y=225
Substituting x with 20-y then
15(20-y)+10y=225
300-15y+10y=225
Collecting like terms
300-225=15y-10y
75=5y
Y=75/5=15
To find x, we already know that x=20-y hence x=20-15=5
Therefore, children tickets are 15 while adult tickets are 5.
The question only needs us to know the children tickets, y which is 15
Yes cuz it's in y=mx+ b form, it makes straight line
Answer:
Is a right triangle
Step-by-step explanation:
step 1
Find the measure of angle C
Remember that
The sum of the internal angles of a triangle must be equal to 180 degrees
so

substitute the given values


therefore
The triangle is a right triangle, because has a internal angle of 90 degrees
Answer:
Step-by-step explanation:
For Mia:
distance,d = 100 yard
time, t = 2 min 33 sec = 153 s
Speed = distance / time
speed = 100 / 153 = 0.65 yard/s
For Larisa:
distance, d = 350 yard
time, t = 5 min 18 sec = 318 s
speed = 350 / 318 = 1.1 yard/s
So, the speed of Larisa is more than the speed of Mia.
