Greg added 3 hundreds plus 2 tens and got 32. What did he do wrong?

Divide $62.50 by 5, and your answer will be $12.50 per ticket.

100 + 10m = 15m

5m = 100

m=20 movies

20 is the amount of movies to make it cost the same.

To find the number of movies at which the cost of both movie clubs would be the same, you set the cost equations for both clubs equal to each other and solve for the number of movies, m. The result is m=20.

The subject here is essentially figuring out where the total cost of each movie club is equal. In this case, we can define two equations representing the total costs of each movie club. For the first club, which charges a $100 membership fee and $10 per movie, that equation is C1 = 100 + 10m . For the second club, which charges no membership fee but $15 per movie, the equation is C2 = 15m. Setting these two equations equal to each other gives us 100 + 10m = 15m. Solving for m (the number of movies) we subtract 10m from both sides to get 100 = 5m, then divide both sides by 5, to find that m = 20.

Therefore, if you plan to buy 20 or more movies in a year, the first club would be more cost effective. If you plan to buy less than 20 movies, the second club would be the better option.

Answer:

[tex]x \leq 40 / 0.25\\ x \leq 160\\[/tex]

Step-by-step explanation:

If the spending limit is $ 40 and making each beads costs $ 0.25, then the amount of accounts you must do  multiplied by the manufacturing cost should not exceed $ 40.

Then the inequation that this restriction would represent is:

[tex]0.25x\leq 40\\[/tex]

Where x is the number of beads made.

This could also be written more specifically:

[tex]x \leq 40 / 0.25\\ x \leq 160\\[/tex]

Therefore the number of beads must be less than or equal to 160

The first step is to figure out what angle DEB is equal to. Check out the attached image. I've marked this as angle y and it is shown in purple.

Note how the purple angle y and the orange 160 degree angle form a straight angle (180 degrees). So the two angles add to 180. Let's solve for y

(orange angle) + (purple angle) = straight angle

(angle CEB) + (angle DEB) = angle CED

y+160 = 180

y+160-160 = 180-160 ... subtract 160 from both sides

y = 20

----------------------------------

Now we can use this to figure out angle x. The three angles x, 115, and 20, combine to 180 degrees as they all glue together to form a straight angle. Let's solve for x:

x+115+y = 180

x+115+20 = 180 ...replace y with 20

x+135 = 180 ......... combine like terms

x+135-135 = 180-135 ...... subtract 135 from both sides

x = 45

Therefore, the final answer is 45

The interval you use when finding the rate of change of a proportional relationship does matter because the behavior of the relationship could vary within different intervals. To illustrate this, consider a proportional relationship where y is directly proportional to x. If we calculate the rate of change for different intervals, we might get different results. Therefore, it is important to specify the interval when finding the rate of change to accurately represent the behavior of the relationship within that interval.

The interval you use when finding the rate of change of a proportional relationship does matter. The rate of change represents how a quantity changes with respect to another quantity. If you use different intervals, you may get different rates of change because the behavior of the relationship could vary within different intervals. Let me provide an example to illustrate this:

Suppose we have a proportional relationship where y is directly proportional to x:

y = kx

If we calculate the rate of change for different intervals, we might get different results. For example, if we consider the interval from x = 1 to x = 5, the rate of change would be (y2 - y1) / (x2 - x1) = (5k - k) / (5 - 1) = 4k / 4 = k. However, if we consider the interval from x = 3 to x = 7, the rate of change would be (y2 - y1) / (x2 - x1) = (7k - 3k) / (7 - 3) = 4k / 4 = k. In both cases, the rate of change is the same within each interval, but it may differ between intervals.

Therefore, it is important to specify the interval when finding the rate of change of a proportional relationship to accurately represent the behavior of the relationship within that interval.

An equivalent ratio of 64:60 is 16:15.

To get an equivalent ratio, you are going to simplify it like you would a fraction. An equivalent ratio would be 32:30. Then, just keep dividing both sides by the same number until both sides can't be divided by the same number. i.e. 9:6 -> 3:2 Both sides were divided by three.

Answer:

Due to decrease in production of tomatoes price will increase.

Step-by-step explanation:

Whenever a commodity whose demand is there in market produce in limited number, it price increases.

Since demand of the tomatoes will remain as usual but limited number of tomatoes will be there in the market so price of the tomatoes will increase. In this way consumer who can afford the price of tomatoes will purchase it and those consumer who can't afford it will not purchase it.

Let’s first know what y=mx+b is.

M= slope

B=y-intercept

Since the problem gives us the slope, we can add it in already, which helps us a lot.

y=4x+b

This problem gives us a coordinate. We can substitute the numbers with the values.

3=4(1)+b

3=4+b

-b=4-3

-b=1

b=-1

Now that we have the y-intercept, we now have the hard parts done and now all we do is put it together.

Answer: y=4x-1

To see if it is correct, we can substitute numbers in (like the coordinate) to see if it was right.

There is your answer!

In mathematics, the absolute value of a number represents its distance from zero on the number line. If X is a rational number and Y is the opposite of X, their absolute values are the same because they are the same distance from zero, regardless of direction.

In the realm of mathematics, rational numbers have a property called absolute value. The absolute value of a number is its distance from zero on the number line, regardless of direction. So, if X is a rational number, Y being its opposite means it is the same distance from zero, but in the other direction.

For example, if X = 3 (a rational number), then Y = -3 (the opposite of X). Despite X and Y being opposites, their absolute values are the same: |3| = |-3| = 3, as both are 3 units away from zero.

Hence, no matter what values X and Y may have, if Y is the opposite of X (either positive or negative), their absolute values will always be equal because they are the same distance from zero.

The perimeter of the rectangular pattern, formed by arranging 16 squares with an area of 16 square units in a 4x4 layout, is 16 units.

To determine the perimeter of a rectangular pattern formed by arranging 16 squares, each with an area of 16 square units, in a 4x4 layout, we can follow these steps.

First, we know the area of each square is 16 square units, which means the side length of each square is the square root of 16, which is 4 units.

Now, when these squares are arranged in a 4x4 pattern, you have 4 squares along the length and 4 squares along the width. The length and width, in terms of these squares, are both 4 squares.

The perimeter of a rectangular shape is calculated using the formula: Perimeter = 2 × (Length + Width).

Plugging in the values:

Perimeter = 2 × (4 + 4) = 2 × 8 = 16 units.

So, the perimeter of the resulting figure is 16 units. This means, when you trace the outline of this 4x4 arrangement of squares, the total distance around the shape is 16 units. Each side contributes 4 units, and there are four sides, giving us a total perimeter of 16 units. This calculation follows the basic principles of perimeter for rectangular shapes and applies them to the given arrangement.

Explanation:

Solving Linear Equations Using Substitution Method

To solve the system of linear equations 6y - 5x = 5 and x = 2y + 7 using the substitution method, we first take the second equation, which gives us an expression for x, and substitute it into the first equation.

Step 1: Write the second equation x = 2y + 7.

Step 2: Substitute x in the first equation: 6y - 5(2y + 7) = 5.

Step 3: Expand and simplify: 6y - 10y - 35 = 5 ⇒ -4y = 40 ⇒ y = -10.

Step 4: Now that we have y, we substitute it back into the second equation to find x: x = 2(-10) + 7 ⇒ x = -20 + 7 ⇒ x = -13.

Therefore, the solution to the system of equations is x = -13 and y = -10.

Answer:

The ordered pair that satisfies the equation is (7, -1)

Step-by-step explanation:

In order to find this, we can solve by subtracting. Start by stacking the two equations on top of one another and subtracting like terms.

3x + 3y = 18

(-) 2x + 3y = 11

--------------------

x = 7

Now that we have the value for x, we can plug in to either equation to find y.

2x + 3y = 11

2(7) + 3y = 11

14 + 3y = 11

3y = -3

y = -1

Final answer:

By applying the method of subtraction to eliminate one variable, we find that the solution to the system of equations 2x + 3y = 11 and 3x + 3y = 18 is x = 7 and y = -3.

Explanation:

Solving a System of Linear Equations

The two linear equations given are:

To find the solution, we can follow a method similar to the one described for solving simultaneous linear equations. We can subtract the first equation from the second to eliminate the variable y:

This gives us x = 7. Now we can substitute x back into either equation to get the value of y:

2(7) + 3y = 11

By solving this, we get y = -3.

The solution to the system of equations is x = 7 and y = -3.

Note the equal sign. What you do to one side, you do to the other.

First, combine like terms

-7x + -7x = -14x
