Answer:

Solution given;

let dogs be d and cats be c.

according to the question

3 d +5 c =$365........[1]

5d+3c=$491.............[2]

By doing elimination method

multiplying equation 1 by 5 and equation 2 by 3 and subtracting

we get

15d+25c=$365*5

15d+9c=$491*3

Answer:

-4 ≤ x ≤ 6

Step-by-step explanation:

Firstly, let us have a random number between the two digits

We can call this random number x

So now, we have to position x between these two numbers

So to ensure that the two numbers are in the range of our values, we have to use an equality statement that will cover both

So by using lesser than or equal to we can incorporate the two extremes

The inequality here is thus ;

-4 ≤ x ≤ 6

Step-by-step explanation:

Answer:

Let the three consecutive numbers be x,x+1,x+2 . The numbers are: 23,24,and25 and the smallest one is 23

Step-by-step explanation:

Answer: (x-1) + (x) + (x+1) = 72; smallest number is 23.

Step-by-step explanation:

The numbers are consecutive, meaning they sit next to each other on a number line. For example 4, 5, 6.

Because they are three consecutive numbers, their average will be the value of the middle one. For example the average of 4, 5, 6 is 5.

Knowing this, we can divide 72 by three to get the value of the middle number.

72/3 = 24, so the middle number is 24.

The numbers that fall either side of 24 on the number line are 23 and 25, so the three consecutive numbers are 23, 24, 25.

You can also set up and solve the equation: (x-1) + (x) + (x+1) = 72 because the numbers are consecutive.

To solve, combine like terms. The (-1) and (+1) cancel out and the equation becomes 3x = 72.

72/3 = 24, so x = 24, and the smallest term, (x-1) = 23.

Answer:

Part A: 299 + 45A + 30B + 50c

Part B: 569 (or 570 if you round it up)

Step-by-step explanation:

Part A:

Because there is no variable for the number of PlayStation 4s, let's assume that there is only one. That will be 299.

If A is the number of wireless controllers and each wireless controller is worth 45 dollars each, the price for the wireless controller(s) is 45A.

If B is the number of wireless controller charging stations and each wireless controller charging station cost 30 dollars, then the price of the wireless controller charging station(s) is 30B

If C is the number of games and each game cost 50 dollars, then the price of the game(s) is 50C

Put that all together, and we get 299 + 45A + 30B + 50c.

Part B:

Let's plug the numbers into the formula.

A = 2

B = 1

C = 3

[tex]299 + 45A + 30B + 50c = 299 + 90 + 30 + 150 = 569\ dollars[/tex]

Answer:

Step-by-step explanation:

Answer:

Angle 1 - 51

Angle 2 - 39

Angle 3 - 90

Angle 4 - 51

Angle 5 - 17

Angle 6 - 129

Step-by-step explanation:

Angle 1 = 180 - 90 - 39 = 51

Angle 2 = 90 - Angle 2 (51) = 39

Angle 3 = 90

Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51

Angle 5 = 180- 90 - 34 -39 = 17

Angle 6 = 180 - Angle 4 (51) = 129

Step-by-step explanation:

|3x - 4| = 6

3x-4 = 6 or 3x-4 = -6

3x=6+4 3x=-6+4

3x=10 3x = -2

x= 10/3 x = -2/3

so, x1= 10/3 or x2 = -2/3

Answer:

Step-by-step explanation:

that what a is (x-8, y+5)

Answer:

A. √(e + 14)

Step-by-step explanation:

[tex]\frac{dy}{dx} = \frac{e^{x} - 1}{2y}[/tex]

separating the variables, we have

2ydy = ([tex]e^{x}[/tex] - 1)dx

integrating, we have

∫ydy = ∫([tex]e^{x}[/tex] - 1)dx

∫ydy = ∫[tex]e^{x}[/tex]dx - ∫1dx + C

2y²/2 = [tex]e^{x}[/tex] - x + C

y² = [tex]e^{x}[/tex] - x + C

when x = 0, y = 4

So,

y² = [tex]e^{x}[/tex] - x + C

4² = [tex]e^{0}[/tex] - 0 + C

16 = 1 + C

16 = 1 + C

C = 16 - 1

C = 15

So,

y² = [tex]e^{x}[/tex] - x + 15

when x = 1, we find y

y² = [tex]e^{1}[/tex] - 1 + 15

y² = e + 14

y = √(e + 14)
