The ratio of games won at to the games lost for a basketball team is 3:2. The team won 18 games. How many games did the team los

schepotkina [342]

A ratio of 3:2.

The easiest way to go about this is to divide the actual number of wins (18) by its corresponding element in the ratio.

So:

$\frac{18}{3}= 6$

This means every element on the ratio has a value of 6.

The amount of element in the ratio that correspond to losses is 2.

Multiply the actual amount of matches per element in the ratio by the number of elements that represents the losses in the ratio.

$6*2=12$

Your answer:

"The team lost 12 games."

Complete the table using the equation y = 9x + 8.

Volgvan

Answer:

$Y = ( -1) | 8 | 17 | 26 | 35|$

Step-by-step explanation:

$y = 9x + 8 \\ \\ \\ x = ( - 1) \\ y = 9( - 1) + 8 \\ y = - 9 + 8 = - 1 \\ \\ x = 0 \\ y = 9(0) + 8 \\ y = 0 + 8 = 8 \\ \\ x = 1 \\ y = 9(1) + 8 \\ y = 9 + 8 = 17 \\ \\ x = 2 \\ y = 9(2) + 8 \\ y = 18 + 8 = 26 \\ \\ x = 3 \\ y = 9(3) + 8 \\ y = 27 + 8 = 35 \\ \\ \\ Y = ( - 1) | 8 | 17 | 26 | 35|$
