Answer:
The price of the admission is 15.
Step-by-step explanation:
From the information given, you can write the following equations:
a+3e=45 (1)
a+5e=65 (2), where:
a is the admission cost
e is the exhibition cost
First, you can solve for a in (1):
a=45-3e (3)
Second, you can replace (3) in (2):
45-3e+5e=65
45+2e=65
2e=65-45
2e=20
e=20/2
e=10
Finally, you can replace the value of e in (3):
a=45-3e
a=45-3(10)
a=45-30
a=15
According to this, the price of the admission is 15.
Answer:
d
Step-by-step explanation:
Part A The area is L times W so (6x^2+3x-2)(x^3-2x+5) so you times like terms since 6x^2 and x^3 has no like terms it ends up like this x^3+6x^2-6x-10 that is the area Part B and Part C i dont know im sorry
Answer:
its 2•8
u add all together then divide it number of times e.g 2+3+4+5+0+1+3+3+4+3=28
so 28/10= 2•8
24a ^ 2-6a-9.
you should do in this case is to see the terms that are repeated in the expression.
WE have then that the terms are a and the multiples of 3.
Making a common factor we have:
24a ^ 2-6a-9.
3 (8a ^ 2-2a-3).
3 (a (8a-2) -3)
Answer:
The equivalent expression is:3 (a (8a-2) -3)
