Answer:
28 x 48 = 1344 - 5X43=170
1344-170=1174
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
Answer:
1- 3(BDE)
2- 37.18 (83.36 - 46.18=64)
3- 64 (83.36 - 19.36)
4- 140.2 (56.84 + 83.36=140.2)
Answer:
Step-by-step explanation:
<u>The function in vertex form:</u>
<u>x- intercepts are 15 and 35:</u>
- 0 = a(15 - 25)² + 32 or 0 = a(35 - 25)² + 32
- 0 = a*100 + 32
- 100a = - 32
- a = -32/100
- a = -8/25 or -0.32
