Answer: she played 5 games and went on 8 rides

Step-by-step explanation:

Let x represent the number of games that Sydney played.

Let y represent the number of rides that Sydney went on.

Each game cost $1.25 and each ride cost $2.25. If Sydney spent $24.25 altogether at the carnival, then the expression is

1.25x + 2.25y = 24.25- - - - - - - - - - -1

If the number of rides that she went on is 3 more than the number of games that she played, the expression would be

y = x + 3

Substituting y = x + 3 into equation 1, it becomes

1.25x + 2.25(x + 3) = 24.25

1.25x + 2.25x + 6.75 = 24.25

3.5x = 24.25 - 6.75

3.5x = 17.5

x = 17.5/3.5

x = 5

y = x + 3 = 5 + 3

y = 8

How can you use division to find the decimal equivalent of a rational number ?
Naily [24]

Answer:

Rational numbers' decimal representations either finish or repeat a pattern. Divide the top by the bottom, the numerator by the denominator to convert fractions to decimals, and if the division doesn't come out evenly, round off after a specific number of decimal places.

Please help STRUGGLING with math few math questions! Ty
-BARSIC- [3]

Question 1:


F(x) and g(x) are like variables, just plug into the equation.


f(x) + g(x) = (x + 6) + (12x - 7)


x+6+12x-7 = 13x-1


Question 2: f(3) + g(-1)


You plug in the x-values into the equation, and then take the answer and add them together.


f(3) = 3+4

g(-1) = 12(-1)-6


f(3) = 7

g(-1) = -18


7 + (-18) = -11


Question 3:


This is similar to question 1, plug in the variables and simplify.


9x - (7x+3)


Remember to distribute the "-"


9x - 7x - 3

2x - 3

A pharmacist has 80 milileters of a 25 percent saline solution. Which expression can be used to find the percentage of the conce
Thepotemich [5.8K]

Answer:


Step-by-step explanation:

Final concentration % = [grams of salt / mililiters of solution] * 100


grams of salt = grams of salt from solution 1 + grams of salt from solution 2


grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g


grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x


mililiters of final solution = mililiters from solution 1 + mililiters from solution 2


mililiters of final solution = 80 mililiters + x mililiters


=> Final concentration, %  =  [0,10x + 20 g] / [x + 80 mililiters] * 100
