Answer:It equals 0.

Step-by-step explanation:

Because the 56 in parenthesis is a negative so when you add it equals nothing.

Answer:

Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.

The cost of 4 hamburguers can be represented with this expression:

4x4x

And the cost of 6 soft drinks  can be represented with this expression:

6y6y

Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:

4x+6y=344x+6y=34   [Equation 1]

 The following expression represents the the cost of 3 soft drinks:

3y3y

According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:

4x+3y=254x+3y=25 [Equation 2]

Therefore, the Equation 1 and the Equation 2 can be used to determine the price of a hamburger and the price of a soft drink

Answer:

3x + 6y = 27

3x + 3y = 18

x = $3, y = $3

Step-by-step explanation:

I will solve by using the elimination method.

3x + 6y = 27

3x + 3y = 18

Subtract top equation by bottom.

3x + 6y = 27

- (3x + 3y = 18)

_____________

  0 +  3y  =  9

3y = 9

y = 3

Plug y in for three

3x + 6*3 = 27

3x + 18 = 27

3x = 9

x = 3

So, your solution is x = $3, y = $3

Answer:

6 different wallpapers

Step-by-step explanation:

Given

[tex]Colours = 27[/tex]

[tex]Textures = 14[/tex]

[tex]Total = 2268[/tex]

Required

Determine the number of different wallpapers he can choose from

From the question, he can choose 1 from 27 colors;

The number of ways is:

[tex]Colours = ^{27}C_1 = \frac{27!}{(27 - 1)!*1!} = \frac{27!}{26!*1!} = = \frac{27*26!}{26!*1} = 27[/tex]

From the question, he can choose 1 from 14 textures;

The number of ways is:

[tex]Textures = ^{14}C_1 = \frac{14!}{(14 - 1)!*1!} = \frac{14!}{13!*1!} = \frac{14*13!}{13!*1} = 14[/tex]

Assume the total number of wallpapers is x and he can only select 1.

The number of ways of selection is:

[tex]Wallpapers = ^{x}C_1 = \frac{x!}{(x - 1)!*1!} = \frac{x* (x - 1)!}{(x - 1)!*1!} = x[/tex]

So, the total selection is:

[tex]Colours * Textures * Wallpapers = Total[/tex]

[tex]27 * 14* x= 2268[/tex]

[tex]378* x= 2268[/tex]

Divide both sides by 378

[tex]\frac{378* x}{378}= \frac{2268}{378}[/tex]

[tex]x= \frac{2268}{378}[/tex]

[tex]x= 6[/tex]

Hence, the number of different wallpaper is 6

Step-by-step explanation:

Answer:

Cost of pizza = 1.25x + 11.99

Step-by-step explanation:

Since Toppings cost the same and the pizza orders are of same size :

Alto ordered for 3 Toppings + pizza = 15.74

Brian ordered for 2 toppings + pizza = 14.49

Hence the cost per topping and pizza could be found :

Cost per topping :

15.74 - 14.49 = 1.25

Hence, slope = 1.25

The intercept, c represents the cost of pizza alone :

Cost of pizza + 2 Toppings = 14.49

Cost per topping = 1.25

Cost of pizza = 14.49 - 2(1.25)

Cost of pizza = 14.49 - 2.50 = 11.99

Expressing in slope - intercept form :

y = mx + c

m = slope ; c = intercept

Cost of pizza = 1.25x + 11.99

Answer:

a squared + b squared = c square

Step-by-step explanation:

In this formula c represents the length of the hypotenuse a and b are the legnths of the other two sides. if two sides of a right triangle are known you can subsitute these values in the formula to find the missing side

Answer:

120 apples

Step-by-step explanation:

Given data

Total amount= $72

Cost per apple = $0.60

The number of apples = Total amount/Cost per apple

substitute

The number of apples= 72/0.6

The number of apples= 120 apples

Hence he will buy 120 apples

It should be noted that since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.

A number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values. From the previous problem, the total distance covered by the rabbit is given by:

Total distance = 4 units + 2 units + 1 unit

Total distance = 7 units.

Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:

Total distance = 10 units + 7 units

Total distance = 17 units.
