Sheila is going to the arcade with only 15 dollars to spend. The cost of each game is 75 cents and the price of admission into the arcade is 5 dollars. Which inequality can be used to solve for g, the number of games that she can play, and what is the maximum number of games she can play?

A - 5g + 0.75 <_ 15, 13 games
B - 0.75g + 5 <_ 15, 14 games
C - 0.75g + 5 <_ 15, 13 games
D - 5g + 0.75 <_ 15, 14 games

Answers

Answer:

C

Step-by-step explanation:

It is 75 cents a game plus 5 dollars admission. You should automatically subtract 5 dollars for admissions. That would give you ten dollars. You would just multiply how many games by how much they cost.

(You can also find the number of games first, and then solve the two inequalities that match that number backwards)

(5x+6) over 2 = 3 (4x+12)

Answers

x= -66/19

Multiply 2 on both sides:

2*(5x+6)/2=3(4x+12)*2

Simplify:

5x+6=24x+72

Subtract 6 from both sides:

5x+6-6=24x+72-6

Simplify:

5x=24x+66

Subtract 24x from both sides:

5x-24x=24x+66-24x

Simplify:

-19x=66

Divide both sides by -19

-19x/-19=66/-19

Simplify:

x= -66/19

The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x + 4 represent the third integer.

Which equation can be used to find the first integer?




3x + 126 = 2x + 6

3x + 6 = 126

2x + 6 = 126

3x = 2x + 6

Answers

Answer:

3x + 6 = 126

Step-by-step explanation:

If you add all of them

x + x+2 + x+4 = 126

simplify the left-side

3x+6=126

subtract 6 from both sides and you get

3x = 120

divide both sides by 3

x=4
