Answer:

X=150

Step-by-step explanation:

30+x=180

30+(-30)+x=180+(-30)  Get x by itself by subtracting -30 to both sides.

x=180-30

x=150

Let t = time in hrs for both to go 32 mi

Let s = Carl's speed in mi/hr

s + 2 = Caits speed in mi/hr

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

Carl's equation:

(1) 24 = s · t

Cait's equation:

(2) 32 = (s+2) · t

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

(2) 32 = s · t + 2t

and

(1) s = 24/t

Plug (1) into (2)

(2) 32 = (24/t) · t + 2t

(2) 32 = 24 + 2t

(2) 2t = 8

(2) t = 4

and

(1) s = 24/4

(1) s = 6

The speed of Cait is 8 mph

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to different addition, subtraction, multiplication, and division arithmetic operations.

Let x be the time in hours for both to go 32 miles

Let y be Carl's speed

Then Caits speed  is = y+ 2

So, Carl's equation:

x y= 24

and, Cait's equation:

32 = (y+2) · x

32 = xy + 2x...............(1)

and, y = 24/x

Put the above value in equation (1)

(24/x) x + 2x = 32

2x+ 24 = 32

2x= 8

x=4

Also, y= 24/x= 24/4 = 6

Hence, speed of Cait is 8 mph

Answer:

Negative: (-∞,-3] and [1/2,-∞)

Positive: [-3,1/2]

Step-by-step explanation:

The derivative is the instantaneous rate of change at any given point for a function. Given this we know that anywhere the function is in the positive or negative direction, the derivative will also be in the positive or negative direction. We also know that wherever there is a peak or a trough, there will be no slope and it signifies a change in direction. For this function, this means the direction changes at -3 and 1/2.

Answer:

Q 1) 7$ Q 2) 50 Q 3) 15$

Step-by-step explanation:

1) The cost of 1 claypot = $7

2) Total amount sold to yield the given profit = $1100

3) Amount to sell each pot to make the given profit = $22

We are given that;

Cost of 50 pots = $350

Cost of 1 clay pot = 350/50 = $7 per clay pot

This means amount she sold in order to make the profit will be;

$350 + $750 = $1,100

1100/50 = $22 per pot

Answer: An unopened can of Diet Dr. Pepper is the least dense.

Step-by-step explanation:

For a solid object to float in a liquid, it must be less dense.

Let's associate the density of Diet Dr. Pepper with x, Dr. Pepper with y, and lake water with z.

Because of the above fact, x < z, and y > z.  Thus, x < z < y, and x < y.

Answer:

  x² +2/3x -1/9 = 0

Step-by-step explanation:

The quadratic with roots p and q can be written as ...

  (x -p)(x -q) = 0

  x² -(p+q)x +pq = 0

For p=(-1-√2)/3 and q=(-1+√2)/3, we have ...

  p +q = (-1-√2)/3 +(-1+√2)/3 = -2/3

  pq = ((-1-√2)/3)((-1+√2)/3) = (1 -2)/9 = -1/9

Then the quadratic is ...

  x² +2/3x -1/9 = 0

Answer:

Step-by-step explanation:

The relation you're supposed to apply here is ...

  an exterior angle of a triangle is equal to the sum of the remote interior angles.

__

The exterior angle is 17x+7, and it is equal to the sum of the two marked angles inside the triangle.

  17x +7 = 13x +3 +40

  4x = 36 . . . . . . . . . . . . . subtract 13x+7 from both sides

  x = 9 . . . . . . . . . divide both sides by 4

Step-by-step explanation:

-x/3 < -4

-x < -12

x > 12

5x +11 ≤ -4

5x ≤ -4-11

5x ≤ -15

x ≤ -3

therefore, the solution is

x ≤ -3 or x > 12

Step-by-step explanation:

Answer:

p = - 5, q = 10

Step-by-step explanation:

If f(x) is divisible by (x - h) then f(h) = 0

Here

f(x) = [tex]x^{4}[/tex] + x³ - 7x² + px + q

dividing by (x - 1) with h = 1 , then

[tex]1^{4}[/tex] + 1³ - 7(1)² + p + q = 0, that is

1 + 1 - 7 + p + q = 0

- 5 + p + q = 0 ( add 5 to both sides )

p + q = 5 → (1)

Dividing by (x + 2) with h = - 2 , then

[tex](-2)^{4}[/tex] + (- 2)³ - 7(- 2)² - 2p + q = 0 , that is

16 - 8 --- 28 - 2p + q = 0

- 20 - 2p + q = 0 ( add 20 to both sides )

- 2p + q = 20 → (2)

Subtract (1) from (2) term by term, thus eliminating q

- 3p = 15 ( divide both sides by - 3 )

p = - 5

Substitute p = - 5 into (1) and solve for q

- 5 + q = 5 ( add 5 to both sides )

q = 10

Answer:

Part A: $13.76 saved. Part B: $55.04

Step-by-step explanation:

Part A: Set a proportion up d/68.8 = 20/100

100·d=100d 68.8·20=1376

100d/100 cancels out

1376/100=13.76 so $13.76 was saved

Part B: 68.80-13.76= 55.04 so $55.04 was what he paid.

Got it! Here you go!

Step-by-step explanation:

It seems you already know that you need to do 17-2/3(not two thirds, just over 3.)

The horizontal line means divide, so you will be dividing by 3. First, though,, you do...

17-2(which is 15)

and then divide it by 3.

15/3=5

Your answer is 5.
