Answer:

-4 = ?

Step-by-step explanation:

<u>Step 1: Substitute -1 for x</u>

7x^3 + 5x^2 - 2 = ?

7(-1)^3 + 5(-1)^2 - 2 = ?

7(-1) + 5(1) - 2 = ?

Rom4ik [11]

Answer:

$S : T = 5 : 8$

Step-by-step explanation:

Represent the first half with F and the second with S

We have that:

$F = 9$ --- From the first statement

$S = 2F - 3$ --- From the next statement

Required

Determine the ratio of S to the total point

First, we need to determine the value of S

Substitute 9 for F in $S = 2F - 3$

$S = 2 * 9 - 3$

$S = 18 - 3$

$S = 15$

Next, we determine the total points

$Total = F + S$

$Total = 9 + 15$

$Total = 24$

The ratio of S to total is: (Represent total with T)

$S : T = 15 : 24$

Divide both ration by 3

$S : T = 15/3 : 24/3$

$S : T = 5 : 8$

<em>Hence, the ratio is 5 to 8</em>
