M∠2 = 180 - m∠1 = 180 - 3x   [supplementary angles<span>]

</span>In a triangle, the three interior angles always add to 180° ⇒
m∠2 + m∠3 + m∠5 = 180 <span>
180-3x + 2x+20 + 30 = 180
230 - x = 180
x = 230 - 180
x = 50</span>

Solve the equation 3x + 2 = 4x + 5 using algebra tiles. Which tiles need to be added to both sides to remove the smaller coeffic
Anastasy [175]

Answer:

Step-by-step explanation:

Given the expression

3x + 2 = 4x + 5

1. The smaller coefficient of x is 3

to remove the smaller coefficient

we need to add - 3x to both sides

3x +2 + (-3x) = 4x +5 (-3x)

3x + 2 - 3x = 4x + 5 - 3x

Collecting like terms we have

3x-3x+2= 4x-3x+5

2 = x+ 5

2. The constant on the right side is

5,to remove the constant from the right side of the equation we need to add - 5 to both sides

3x + 2+ (- 5) = 4x + 5 +(-5)

3x+ 2-5 =4x +5-5

3x-3 = 4x

(Need 3 answers) An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n) =
Strike441 [17]

Answer:

  • See below

Step-by-step explanation:

<u>According to the model, the equation is:</u>

  • P(n) = 3450*bⁿ

Based on the equation, the initial number of insects is 3450

<u>If b = 1.75, daily growth rate is:</u>

  • 1.75 - 1 = 0.75 = 75%

<u>If  we get P(4) = 55200, find the value of b:</u>

  • 55200 = 3450*b⁴
  • b⁴ = 55200/3450
  • b⁴ = 16
  • b⁴ = 2⁴
  • b = 2
