Answer:

x=30

Step-by-step explanation:

you distribute the negative to 2x and 19

3x+4-2x-19=15

then you combine like terms

x-15=15

you add 15 to both sides

x=30

Answer:

<em>x = 20</em>

Step-by-step explanation:

We are given the equation ( 3x + 4 ) – ( 2x + 9 ) = 15;

( 3x + 4 ) - ( 2x + 9 ) = 15 ⇒ Take ( ) out, through distribution of - 1,

3x + 4 - 2x - 9 = 15 ⇒ Subtract 4 from either side,

3x - 2x - 9 = 11 ⇒ Combine like terms,

x - 9 = 11 ⇒ Add 9 on either side,

<em>Solution; x = 20</em>

Answer:

  • D. 24736 people and 29 years

Step-by-step explanation:

<u>The model given is:</u>

  • P = 16581*e^(0.02t)

<u>Population in 2020, t = 20</u>

  • P = 16581*e^(0.02*20) = 24736 people (rounded)

<u>Population of 30000:</u>

  • 30000 = 16581*e^(0.02t)
  • e^(0.02t) = 30000/16581
  • e^(0.02t) = 1.80929
  • ln e^(0.02t) = ln 1.80929
  • 0.02t = 0.5929
  • t = 0.5929/0.02
  • t = 29.645 ≈ 29 years

Correct choice is D

Use formulas to find the lateral area and surface area of the prism.
TiliK225 [7]

Step-by-step explanation:

Finding surface area

To find the surface area of a prism, use the formula SA=2B+ph, where SA stands for surface area, B stands for area of the base of the prism, p stands for the perimeter of the base, and h stands for the height of the prism. Since this is a triangular prism, substitute the area formula of a triangle for B.

A numerical data set has 9 values. How many of these values does the data
Paraphin [41]
I think it’s D) 9 because when you find the mean of a set of values you are taking into account and adding all of the numbers, and then dividing them by how many numbers there is, so the mean would be summarizing all of them, hope this helps
