Write an equation from word problem: Juan and his friends decided to go to the Chihuahuas game. Each person paid $44.00 for their ticket and $10 for parking. They spent $186.00. How many people went to the game?

Answers:

44x + 10 = 186

x = 4

Writing the equation:

Look at the equation carefully. What numbers do we know already to put into the equation?

Well, we know that the total number that they all spent was $186, so that's the number we're trying to get the equation to equal. (Where I got = 186 from)

We also know that there was an extra $10 spent on parking, so we add the + 10 to the equation.

Lastly, we know that each person spent $44 on a ticket. However, we don't know how many people were there. That's where the variable (x) comes into play, making your equation 44x + 10 = 186

Solving the equation:

To solve the equation, you have to break it apart.

We know that there were 10 extra dollars spent, therefore, you have to subtract 10 from the total money spent, or in other words, move the constant to the right hand side and change it's sign (44x = 186 - 10). After solving the subtraction part, that will leave you with a new equation, 44x = 176.

Finally, you divide both sides by 44, and that will get you your answer of x = 4.

4 people went to the game.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
