AleksAgata [21]

Answer:

Equation: 10+x= 15 +0.5x

Time: 10 days

Amount: 20$

Step-by-step explanation:

<u>Equation for Benito:</u>

  • 10 + x*1

<u>Equation for Tavon:</u>

  • 15 + x*0.5

<u>Since the sums equalize at some time, we get:</u>

  • 10+x= 15 +0.5x
  • x - 05x = 15- 10
  • 0.5x = 5
  • x= 5/0.5
  • x= 10 days

After 10 days, Juan will owe both Benito and Tavon $20

The weights of cars passing over a bridge have a mean of 3,550 pounds and standard deviation of 870 pounds. Assume that the weig
Annette [7]

Answer:

0.24315

Step-by-step explanation:

Using the z score formula to solve this question

z = (x - μ) / σ,

Such that:

x = raw score

μ = population mean

σ = population standard deviation.

From the question:

x = 3000

μ = 3550

σ = 870

z = (3000 - 3550) / 870

z = -550/870

z = -0.6962

Using the z score table as well as probability calculator(as requested in the question to find the z score)

The probability of having less than 3000 is obtained as:

P(x<3000) = 0.24315

Factor 140c + 28 - 14a to identify the equivalent expressions.
Feliz [49]

Answer:

The answer to your question are letters A, C and D.

Step-by-step explanation:

To factor this polynomial we need to look for the common factor of the three terms.

To find it, get the greatest common factor

                        140    28   14     2

                          70    14     7     2

                          35     7     7     5

                            7     7      7     7

                             1     1       1    

Greatest common factor = 2 x 7 = 14  

Factor the polynomial

140c + 28 - 14a = 14 ( 10c + 2 - a)

Factor only 7          7(20c + 4 - 2a)

Factor only 2          2 (70c + 14 - 7a)

What is the simplified form of the quantity of x plus 8, all over the quantity of 3x plus 7 + the quantity of x plus 7, all over
Temka [501]
\frac{x+8}{3x+7} + \frac{x+7}{x+4}  \\ = \frac{(x+8)(x+4)+(x+7)(3x+7)}{(3x+7)(x+4)}  \\ = \frac{ x^{2} +12x+32+3 x^{2} +28x+49}{3 x^{2} +19x+28}  \\ = \frac{4 x^{2} +40x+81}{3 x^{2} +19x+28}
