Pretty, pretty, pretty please help!!!Which proportion models this problem?

1 answer:

8 0

8 of 19 players said that they had 2 or more siblings.

8 out of 19 is equal to what out of 570

8/19 = x/570

This proportion can be written in different ways.

8/19 = x/570 cross multiplies to 19*x = 8*570

The task is to find a proportion among the answer options that cross multiplies to the same equation.

Option C is x/570 = 8/19. That cross multiplies to 19*x = 8*570 and is the correct answer.

Given ƒ(x) = 14x + 42, find x when ƒ(x) = 35. A) − 12 Eliminate B) −1 C) 1 D) 3

balandron [24]

Step-by-step explanation:

$f(x)=14x+42$

$f(x)=35$

Given the information above, we can simply set up an equation so we can find the value of x.

$14x + 42 = 35$

Subtract 42 on both sides.

$14x=-7$

Divide 14 on both sides.

$x=-\frac{1}{2}$

So, the value of x is equal to -1/2 when f(x) is 35.
