Admission to Indianapolis children's museum cost five dollars more for an adult then for a child. Admissions to the museum for B
Sergeeva-Olga [200]

Answer:

The admission cost of each adult is $11.5 and that of each children is $6.5.

Step-by-step explanation:

Let the admission cost for children to the museum is $x.

So, the admission cost for adults to the museum is $(x + 5) {As per given condition}

Now, given that admission to the museum for Barbara and Jeff Johnson and their five children cost fifty-five dollars and fifty cents.

Hence, 2(x + 5) + 5x = 55.5

⇒ 7x = 45.5

⇒ x = $6.5  

So, $(x + 5) = $11.5

Therefore, the admission cost of each adult is $11.5 and that of each children is $6.5. (Answer)

What is a simpler form of the expression?<br><br> (2n^2 + 5n +3)(4n - 5)
coldgirl [10]

Answer:

8n³ + 10n² - 13n - 15

Step-by-step explanation:

Distribute the factors by multiplying each term in the first factor by each term in the second factor, that is

4n(2n² + 5n + 3) - 5(2n² + 5n + 3) ← distribute both parenthesis

= 8n³ + 20n² + 12n - 10n² - 25n - 15 ← collect like terms

= 8n³ + 10n² - 13n - 15
