Answer:

150 - 7.50x = 112.50

x = 5

Step-by-step explanation:

Spent in x days: 7.50x

Initial - spent = remaining

150 - 7.50x = 112.50

If x is also to be found:

150-112.5 = 7.5x

37.5 = 7.5x

x = 37.5/7.5

x = 5

Answer:

5 Days

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

150 - 7.50x = 112.50

<u>Step 2:  Solve the expression for x</u>

150 - 7.50x = 112.50

150 - 7.50x - 150 = 112.50 - 150

-7.50x / -7.5 = -37.5 / -7.5

x = 5

Answer:  5 Days

sweet-ann [11.9K]

Answer:

Step-by-step explanation:

Well. There are many possibilities. There are 26 letters in the alphabet. Take the K and W out. You have 24. So, just go through every letter. Putting  them together to make a name, it could be anything really. It might take a while, but write out the alphabet, and see what names you can make starting with K and W. I hope this helped!! :)

Solve the equation 3x-2y =7, x+2y= -3​
swat32

Answer:

  • x=1
  • y= -2

Step-by-step explanation:

  • 3x-2y =7
  • x+2y= -3
  • 4x=4
  • x=4/4
  • x=1
  • 3x-2y=7
  • 3(1)-2y=7
  • 3-2y=7
  • -2y=7-3
  • -2y=4
  • 2y=-4
  • y=-4/2
  • y= -2
  • Verify solution
  • x+2y= -3
  • 1+2y= -3
  • 2y=-3-1
  • 2y= -4
  • y= -4/2
  • y= -2

Answer: 2x^{2} + 5x -3

Step-by-step explanation:

Find the quotient of  \frac{16x^4+40x^3-24x^2}{8x^2}

Step 1: Break down the polynomial equation

\frac{16x^4}{8x^2} + \frac{40x^3}{8x^2} - \frac{24x^2}{8x^2}

Step 2: Divide each piece by dividing the coeffients and subtracting the variables.

16 ÷ 8 = 2

x^{4} - x^{2} = x^{2} → 2x^{2}

40 ÷ 8 = 5

x^{3} - x^{2} = x → 5x

- 24 ÷ 8 = - 3

x^{2} - x^{2} = 1 → - 3

Step 3: Put the polynomial together

2x^{2} + 5x - 3

Part 1:
The pattern for the first sequence goes by the multiples of 12 and you can show your work by adding 12 to the following number. Example:

12 + 12 = 24
24 + 12 = 36
36 + 12 = 48

and go on...

The pattern for the second is one is that you have to multiply by 2. Example:

3 × 2 = 6
6 × 2 = 12
12 × 2 = 24

Part 2:
You would do the same steps shown above. Add twelve to the following number which is 60. So, 60 + 12 = 72. 

You would also need to multiply 2 and 96 since its the given number. 96 × 2 =192.

Part 3: 
The first sequence is an arithmetic sequence because the number 12 is constantly being added.

The second sequence is a geometric sequence because 2 is constantly being multiplied.

I hope this helps!
