Answer:

Sandwich costs $7.70 and the soda costs $2.20

Step-by-step explanation:

First create a ratio:


The sandwich cost 3.5 more than the drink therefore the ratio is 3.5:1


Then add the two sides of the ratio together to get the total parts of the ratio

3.5+1 = 4.5


Now that we know the total parts of the ratio we can solve for one part by dividing the total cost $9.90 by the total parts of the ratio 4.5+


$9.90/4.5 = 2.20


Since we know that each part of the ratio is 2.20 we multiply both sides of the ratio by 2.20


3.5 *2.20 = 7.70

1 * 2.20 = 2.20

A softball team played 149 games. The team won 8 more than two times the number of games they lost. How many games did they lose
BlackZzzverrR [31]

The number of game the softball team lose is 47 games.

<h3 /><h3 /><h3>The softball team played 149 games. </h3>

Total games played = 149 games

The team won 8 more than two times the number of games they lost.

Let

the number of games they lost = x

Therefore,

  • number of game won = 8 + 2x

The number of game they lose can be calculated as follows:

8 + 2x + x = 149

8 + 3x = 149

3x = 149 - 8

3x = 141

x = 141 / 3

x = 47

Therefore, the team lost 47 games.
