Answer: $10
Step-by-step explanation:
Let adults tickets be denoted by a
Let student tickets be denoted by s
On the first day of tickets sale, there were 10 adult tickets and 11 students tickets sold for a total of $190. This will be:
10a + 11s = 190
The second day, there were a total of $160 worth of tickets, 5 adult tickets and 12 student tickets. This will be:
5a + 12s = 160
We combine both equations
10a + 11s = 190 .......... equation i
5a + 12s = 160 ........... equation ii
Multiply equation i by 5
Multiply equation ii by 10
50a + 55s = 950 ....... equation iii
50a + 120s= 1600 ........ equation iv
Subtract equation iv from iii
50a + 55s = 950
- 50a + 120s= 1600
-65s = -650
65s= 650
Divide both side by 65
s = 10
The price for the student's ticket is $10.
16z^2 + 25
This polynomial is already in lowest terms.
Answer: Cannot be factored.
This happens with certain polynomials.
Answer:
D. No, because the differential equation does not have constant coefficients.
Step-by-step explanation:
The undetermined coefficient method cannot be applied to non homogeneous variables. The differential equation does not have constant variables therefore the method of undetermined superposition can not be applied. To complete a solution of non homogeneous equation the particular solution must be added to the homogeneous equation.
Answer:
Kilometers in 1cm=1/1,00,000
=0.00001
Therefore, Kilometers in 3 cm=3×0.00001
=0.00003km
