A system of equations is shown. x = 10 3x + 5y = 20

A System Of Equations Is Shown. X = 10 3x + 5y = 20

Answers

Answer 1

Answer:

(10, - 2 )

Step-by-step explanation:

x = 10 → (1)

3x + 5y = 20 → (2)

Substitute x = 10 into (2)

3(10) + 5y = 20

30 + 5y = 20 ( subtract 30 from both sides )

5y = - 10 ( divide both sides by 5 )

y = - 2

solution is (10, - 2 )

B. Perform the step to have the variables (circles) alone on one side.
C. Write the resulting step.
D. Divide the variables (circles) and numbers (squares) into equal groups.
E. Show the value of one group.

Answers

The value of x in the equation, 3x + 2 = 5 is 1.

In order to solve this equation: 3x + 2 = 5, take the following steps:

Combine similar terms together:

3x = 5 - 2

Add the similar terms together

3x = 3

Divide both sides of the equation by 3 in order to make x the subject f the formula

3x / 3 = 3 /3

x = 1

You plan on joining a gym. The joining fee is $30 and you must pay $12 a month fee. If you have $100, how many months can you use the gym? Write and solve an inequality to represent the solution.

I need the process for this otherwise I won't get credit for it!!

Answers

Answer:

Inequality: 30+12x < 100

x ≈ 5 months

Step-by-step explanation:

To solve, first create the inequality. In this problem, 30 dollars is the flat fee for joining the gym and thus a constant. Additionally, 12 is the monthly payment and thus the coefficient for a variable because it changes with the number of months. Finally, 100 is the most that can be spent (the max), so it should be on the other side of the inequality and the sign should be less than or equal to 100.

This makes the inequality: 30+12x < 100

To find the number of months solve the inequality for x.

30+12x<10012x<70x<5.8

So, the inequality equals x<5.8. However, the question asks for the number of full months. And, no more than 100 dollars can be spent. So, while you would normally round up. In this case, you must round down to 5 months.

Kolby decided he wanted to go to the amusement park. The amusement park charges $8.00 for entry and $1.40 for each ride.
Part A Write an expression to represent this scenario where r represents the number of rides.
Part B Create and solve an equation to determine how many possible rides Deniss can ride if his parents gave him $26.00Show your work.

Answers

Answer:

He pays $8.00 regardless and $1.40 for each ride. When we see for each, we typically want to multiply.

A. $8.00 + $1.40 * r

If his parents gave him $26.00, then that is the most Kolby can spend.

$8 + $1.40 * r = $26

Subtracting 8 from both sides:

$1.40 * r = $18

Dividing both sides by 1.40:

r = 12.86

B. Since you can't ride part of a ride, Kolby can only ride 12 rides.

Step-by-step explanation:

Answer:

An expression to represent this would be 1.40x+8.00= R

1.40x+8=26

       -8   -8

1.40x=18

/1.40    /1.40

x=11 total rides

If you had $26.00 you would first spend $8.00 on the entry leaving you with $18.00. Then you would divide the $18 by $1.40 for each ride to get 12.8... It doesn't make sense to go on a fraction of a ride so you just round down to 11 rides

andre is solving the inequality 14x+3 is less than or equal to 8x+3.he first solves a related equation

14x+3=8x+3 this seems strange to Andre. He thinks he probably
14x=8x made a mistake.What was his mistake?
8=14

Answers

Answer:

14x+3=8x+3

14x+3 -3 = 8x+3 -3

Cancels out the 3

14x = 8x

14x - 8x = 8x -8x

Cancels out the 8x

14x = 0

x = 0

Step-by-step explanation:

Andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Inequality expression

Given the inequality expression solved by andre expressed as:

14x + 3 ≤ 8x + 3

Simplify to have:

14x - 8x ≤ 3-3

6x ≤ 0

x ≤ 0

Hence andre should have collected the like terms in order to have all the variables x on one side before taking the difference.
