Step 2: -2x - 3 = x - 18
Step 3: -3 = 3x - 18
A. Addition Property of Equality
B. Subtraction Property of Equality
c. Multiplication Property of Equality
D. Division Property of Equality

Answer:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Answer:

825

Step-by-step explanation:

Calculation for what The frequency in this interval is equal to:

Using this formula

Frequency=Population size*Relative frequency interval

Let plug in the formula

Frequency=5,500 observations*0.15

Frequency=825

ThereforeThe frequency in this interval is equal to:825

The frequency in this interval is equal to 825.

Given

A population is of size 5,500 observations.

When the data are represented in a relative frequency distribution, the relative frequency of a given interval is 0.15.

The frequency is defined as the product of population size and relative frequency interval.

The following formula is used to calculate frequency in this interval is;

[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\[/tex]

Substitute all the values in the formula;

[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\Frequency= 5500\times 0.15\\\\Frequency= 55\times 15\\\\Frequency= 825[/tex]

Hence, the frequency in this interval is equal to 825.

Answer:

Step-by-step explanation:

Coordinates of the given rectangle are,

A → (3, 3)

B → (6, 3)

C → (6, 1)

D → (3, 1)

Translation of the given rectangle by the vector [tex]\binom{-1}{5}[/tex] means, shifting of rectangle by 1 unit to the left and 5 units up.

So the rule which defines the translation of the vertices by the given vector is,

(x, y) → (x - 1, y + 5)

By this rule, after translation vertices of image rectangle will be,

A(3, 3) → A'(2, 8)

B(6, 3) → B'(5, 8)

Answer:

1. Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)

2.Exact solution x = -0.376

Step-by-step explanation:

Solution:

First we have to write the Expanded Form of [tex]a^{2} . b^{3}[/tex], Let's do it.

1) [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)

Hence,

Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)

2) [tex]4^{5x} = 3^{x-2}[/tex]

Now, we have to find out the exact solution of the above equation:

In order to equate the exponents, we need to make sure the bases are same. Or we simply can use logarithm to solve the above equation.

So,

We are using logarithm to solve this equation.

Let's break this down:

[tex]4^{5x} = 3^{x-2}[/tex]

Taking log on both sides.

log[tex]4^{5x}[/tex] = log[tex]3^{x-2}[/tex]  

[tex]5xlog(4)[/tex] = [tex](x-2)log(3)[/tex]

Dividing both sides by log(4)

[tex]5x[/tex] = (x-2) [tex]\frac{log(3)}{log(4)}[/tex]

value of log(3) = 0.4771

value of log(4) = 0.6020

[tex]5x[/tex] = (x-2) [tex]\frac{log(0.4771)}{log(0.6020)}[/tex] =

5x = (x-2)0.792

5x = 0.792x - 1.584

by rearranging the equation, we get:

0.792x - 5x = 1.584

x(0.792 - 5) = 1.584

x(-4.208) = 1.584

x = -1.584/4.208

x = -0.376

Exact solution x = -0.376

Answer:

x = − 4 .y = − 1

Step-by-step explanation:

Given :

Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill.

To Find :

If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk.

Solution :

Time taken to walk one mile uphill is :

[tex]t_1 = \dfrac{1}{3}\ hours[/tex]

Time taken to walk two mile on flat land( one on going and one or returning ) is :

[tex]t_2 = \dfrac{2}{4}\ hours\\\\ t_2 = \dfrac{1}{2}\ hours[/tex]

Time taken to walk one mile downhill is :

[tex]t_3 = \dfrac{1}{5}\ hours[/tex]

Total time taken :

[tex]T = t_1 + t_2 + t_3 \\\\T = \dfrac{1}{3} + \dfrac{1}{2}+\dfrac{1}{5}\\\\T = \dfrac{10 + 15 + 6}{30} \\\\T = \dfrac{31}{30}\ hours = \dfrac{31}{30}\times 60 \ minutes\\\\T = 62\ minutes[/tex]

Therefore, time taken un 62 minutes.

Answer: Becky will have to spend £ 9.6 .

Step-by-step explanation:

The ratio of their ages will be:

Melissa : Becky : Daniel = 13 : 12 : 10

Total amount share = £42

Share of Becky = [tex]\dfrac{12}{12+13+10}\times42[/tex]

[tex]=\dfrac{12}{35}\times42\\\\= 14.4[/tex]

Hence, Becky's share = £14.4

Becky decided to save a third of her share.

Then, Amount she spend = [tex]14.4-\dfrac13 \times 14.4[/tex]

[tex]=14.4-4.8\\=9.6[/tex]

hence, Becky will have to spend £ 9.6 .

Answer:

Width = 54.3 inches

Step-by-step explanation:

We solve this question using the Pythagoras Theorem

Width² + Height² = Diagonal²

From the above question

Width= ??

Height = 30 inches

Diagonal = 62 inches

Width² + 30² = 62²

Width² = 62² - 30²

Width = √62² - 30²

Width =✓2944

Width = 54.258639865 inches

Approximately

Width = 54.3 inches

Hence, the new television was 54.3 inches wide.
