Answer:

x = 2

Step-by-step explanation:

\rm Solve \:  for \:  x: \\  \rm  \longrightarrow 4 (3 x - 1) = 20 \\  \\  \rm Divide  \: both  \: sides \:  of  \: 4 (3 x - 1) = 20  \: by  \: 4: \\  \rm  \longrightarrow  \dfrac{4(3x - 1)}{4}  =  \dfrac{20}{4}  \\  \\  \rm \dfrac{4}{4}  = 1: \\  \rm  \longrightarrow 3 x - 1 =  \dfrac{20}{4}  \\  \\  \rm \dfrac{20}{4} = 5: \\  \rm  \longrightarrow 3 x - 1 = 5 \\  \\  \rm Add \:  1  \: to  \: both  \: sides: \\  \rm  \longrightarrow 3 x + (1 - 1) = 1 + 5 \\  \\  \rm 1 - 1 = 0: \\  \rm  \longrightarrow 3 x = 5 + 1 \\  \\  \rm 5 + 1 = 6: \\  \rm  \longrightarrow 3 x = 6 \\  \\  \rm Divide \:  both  \: sides \:  of  \: 3 x = 6 \:  by \:  3: \\  \rm  \longrightarrow  \dfrac{3x}{3}  =  \dfrac{6}{3}  \\  \\  \rm \dfrac{3}{3}  = 1: \\  \rm  \longrightarrow x =  \dfrac{6}{3}  \\  \\  \rm \dfrac{6}{3}  = 2 : \\  \rm  \longrightarrow  x = 2

A scientist is studying wildlife. She estimates the population of bats in her state to be 326,000. She predicts the population t
kvasek [131]

The equation that models the population of bats is 326,000 x (1.014)^X = Y, so the correct answer is A.

<h3><u>Equations</u></h3>

Given that a scientist is studying wildlife, and she estimates the population of bats in her state to be 326,000, and she predicts the population to grow at an average annual rate of 1.4%, to create an equation that models the population of bats, Y , after X years, the following calculation must be made:

  • 326,000 x (1+ 1.4/100)^X = Y
  • 326,000 x (1 + 0.014)^X = Y
  • 326,000 x (1.014)^X = Y

Thus, in 3 years, the equation would operate as follows:

  • 326,000 x 1.014^3 = Y
  • 326,000 x 1.0425 = Y
  • 339,884.58 = Y

A 15-meter by 23-meter garden is divided into two sections. Two sidewalks run along the diagonal of the square section and along
Thepotemich [5.8K]

Solution:

We have re-drawn the given diagram, as we can see the given rectangle is actually divided into two parts.

one is Large square and the other one is a smaller rectangle.

Now we will apply the Pythagoras theorem in the larger triangle which is inside the square.

So we can write

Diagonal_1=\sqrt{15^2+15^2}= 21.213

Now we will apply the Pythagoras theorem in the smaller  triangle which is inside the smaller rectangle.

So we can write

Diagonal_2=\sqrt{15^2+8^2}= 17

The approximate sum of the lengths of the two sidewalks, shown as dotted lines=21.2+17=38.2 m

Hence the correct option is D
