Ellie is going to a carnival that has games and rides. Each game costs $2.50 and each ride costs $3.50. How much would Ellie have to pay if she wanted to play 5 games and go on 7 rides? How much would Ellie have to pay if she wanted to play xx games and go on yy rides?5 games and 7 rides:
Answers
1 game (x) = 2.50
1 ride (y) = 3.50
5x + 7y
5(2.50) + 7(3.50)
12.50 + 24.50
37
Ellie would have to pay $37 to play 5 games and go on 7 rides.
Hope this helps!! :)
Answer:
$37
Step-by-step explanation:
You are given the prices of the games and the rides.
First you find the games. Since there are 5 games, you do 2.50 * 5. This gives you 12.5. She would have to have $12.50 to spend.
Next, you do the rides. There are 7 rides, each for 3.50, so you do 3.50 * 7, giving you 24.50. She would have to have $24.50 to spend on rides.
Now the question asks how much she would have to pay to do both. This means you add your values:
12.5 + 24.5 = $37.

Please help I'm desperate...Solve the systems:a. y=50+3x y=100-2xb. x+3y=9 -3x+2y=8Thanks for helping (will give brainliest <3)
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why?
(4, 14), because one of the lines passes through this point
(4, 14), because the point lies between the two axes
(5, 17), because both lines pass through this point
(5, 17), because the point does not lie on any axis
Answers
x+12 = y = y = 3x+2
x+12=3x+2 |-2
x+10=3x |-x
10=2x |/2
5=x
x+12 = y => 5+12 = y =>y = 17
(x,y) => (5,17)
Answer:
5,17
Step-by-step explanation:
9(x2 + 6x) = 7
9(x2 + 6x + 9) = 7 +.?
Answers
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
9x2 +54x = 7
2. Make sure that the coefficient of the x^2 term is 1.
9(x2 + 6x) = 7
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
9(x2 + 6x + 9) = 7 + 81
9(x+3)^2 = 88
Answer:
? = 81

Answer:
-32 :) is the answer just think about it as your adding the sum of these numbers then putting a negative in front of it.
Step-by-step explanation:
Equation 2: 3m = 4 + 4n
Step 1:
−3(m) = −3(8 + 2n) [Equation 1 is multiplied by −3.]
3m = 4 + 4n [Equation 2]
Step 2:
−3m = −24 − 6n [Equation 1 in Step 1 is simplified.]
3m = 4 + 4n [Equation 2]
Step 3:
−3m + 3m = −24 − 6n + 4n [Equations in Step 2 are added.]
Step 4:
0 = −24 − 2n
Step 5:
n = −12

Answer:
Step 3
Step-by-step explanation:
Hello
the student made a mistake in the step number 3.
let´s see
in the step number 1 he multiplied by -3 in order to add this new equation with equiation 2 and then eliminate the terms with m
Step one
-3(m)=-3(8+2n)
-3m= -24 - 6 n, it is ok
in step two he simplified, he did it well.
in the step 3 he added the equations
-3m = -24-6n
3m = 4 +4n
_____________
0 = -20-2n
he did not add properly -24+4, here , he made his first mistake.
step 4 is already wrong
continuing..to find n
0= -20-2n
20=-2n
n=-10
Have a great day
