((6+x))/(3)=(x)/(4)+4

mr Goodwill [35]

Answer:

x = 24

Step-by-step explanation:

$\frac{6+x}{3}$ = $\frac{x}{4}$ + 4 Multiply though by 12 to clear the fraction

4(6 + x) = 3x + 48 Distribute the 4)

24 + 4x = 3x + 48 Subtract 3x from both sides of the equation

24 + x = 48 Subtract 24 from both sides.

x = 24

The number of rows in an auditorium can be represented by the function f(x) = 80x. The number of seats in each row can be repres

rusak2 [61]

Answer:

$h(x) = 80x^2 + 560x$

Step-by-step explanation:

To find the function h(x), that represents the total number of seats, we just need to multiply the functions f(x) (number of rows) and g(x) (number of seats per row):

$h(x) = f(x) * g(x)$

$h(x) = 80x * (x+7)$

$h(x) = 80x*x + 80x*7$

$h(x) = 80x^2 + 560x$

So the function that represents the total number of seats is:

$h(x) = 80x^2 + 560x$
