Answer:
No
Step-by-step explanation:
To solve this question,you will have to represent the variables with a specific letters so as to make the solving easier
Ok...let the soap be y and the lotion be x
2y+5x=20...(1)
6y+15x=50...(2)
Multiply (1) by 15
30y+75x=300...(3)
Multiply (2) by 5
30y+75x=250...(4)
If we should compare both (3) and (4) there is no way to eliminate any of these variables... because to solve this problem we will have to use elimination methods
Therefore it is not possible to get the actual price of any of them that is the soap and the lotion
Adults: $22
Children: $22 - $5 = $17
22a + 17c = t
22(12) + 17(15) = t
264 + 255 = $519
The total cost of admission is $519.
Hope this helped!
Answer:
a = 2.4
Step-by-step explanation:
The problem statement tells you ...
b/a = 6
b - a = 12
Using the first equation, we can write an expression for b:
b = 6a . . . . . . . multiply both sides by "a"
This can be substituted into the second equation to find a value for "a":
6a -a = 12
5a = 12
a = 12/5 = 2.4
The value of a is 2.4.
Answer:
it only has four solutions
Answer
x= -7, -1
Step-by-step explanation:
x^2= -7x- 8
x^2+ 7x+ 8 =0
x+7=0 x+1=0
x=-7 x=-1
