To make A the subject in the equation w = 3(2a + b) - 4, the rearranged equation is: a = (w + 4 - 3b) / 6.

To rearrange the equation w = 3(2a + b) - 4 to make A the subject, we need to isolate A on one side of the equation. Here's how we can do it step by step:

Step 1: Distribute the 3 to the terms inside the parentheses:

w = 6a + 3b - 4.

Step 2: Move the 3b and -4 terms to the other side of the equation:

w + 4 = 6a + 3b.

Step 3: Rearrange the terms to isolate a:

6a = w + 4 - 3b.

Step 4: Divide both sides of the equation by 6 to solve for a:

a = (w + 4 - 3b) / 6.

Now, a is the subject of the equation. We have successfully rearranged the equation to express a in terms of w and b.

The probable question maybe:

rearrange w=3(2a+b)-4 to make A the subject in the equation.

The rearranged equation solving for [tex]\( a \)[/tex] is : [tex]\[ a = \frac{{w + 4}}{6} - \frac{{b}}{2} \][/tex]

This equation expresses [tex]\( a \)[/tex] as a function of [tex]\( w \)[/tex] and [tex]\( b \)[/tex], where [tex]\( w \)[/tex] is multiplied by [tex]\( \frac{1}{6} \) and \( b \)[/tex] is subtracted and then divided by [tex]\( 2 \)[/tex]. This equation can be used to calculate the value of [tex]\( a \)[/tex] given [tex]\( w \) and \( b \).[/tex]

To rearrange the equation [tex]\( w = 3(2a + b) - 4 \)[/tex] to solve for [tex]\( a \)[/tex], the first step is to isolate the term containing [tex]\( a \)[/tex] on one side of the equation.

1. Start by distributing the [tex]\( 3 \)[/tex] on the right side:

[tex]\[ w = 6a + 3b - 4 \][/tex]

2. Next, move the constants to the other side of the equation by adding [tex]\( 4 \)[/tex] to both sides:

[tex]\[ w + 4 = 6a + 3b \][/tex]

3. Now, to isolate [tex]\( a \)[/tex], divide both sides by [tex]\( 6 \):[/tex]

[tex]\[ \frac{{w + 4}}{6} = a + \frac{{3b}}{6} \][/tex]

4. Simplify:

[tex]\[ \frac{{w + 4}}{6} = a + \frac{{b}}{2} \][/tex]

5. To solve for [tex]\( a \)[/tex], subtract [tex]\( \frac{{b}}{2} \)[/tex] from both sides:

[tex]\[ \frac{{w + 4}}{6} - \frac{{b}}{2} = a \][/tex]

So, the rearranged equation solving for [tex]\( a \)[/tex] is:

[tex]\[ a = \frac{{w + 4}}{6} - \frac{{b}}{2} \][/tex]

The side lengths that model a rectangle with an area of x^2 + 3x – 10 are x + 5 and x – 2, obtained by factoring the quadratic expression.

To find the side lengths of a rectangle that model an area of x2 + 3x – 10 square units, we need to factor this quadratic expression. Factoring involves finding two binomials that when multiplied together, give the original quadratic expression. The factors of -10 that add up to 3 (the coefficient of the middle term) are 5 and -2. Therefore, the factored form of x2 + 3x – 10 is (x + 5)(x – 2), meaning the side lengths that can be used to model this rectangle are x + 5 and x – 2.

Answer:

The Answer is 5 1/8

Step-by-step explanation:

Answer: 2 and 4/5

Step-by-step explanation: To write an improper fraction as a mixed number, divide the denominator into the numerator.

[tex]\sqrt[5]{14}[/tex] = 2 with a remainder of 4

Therefore, 14/5 can be written as the mixed number 2 and 4/5.

The fraction 14/5 written as a mixed fraction is equivalent to 2 4/5

Given the expression below:

14/5

Since 5 can go in 14 twice, the whole number of the mixed fraction will be 2.

Given the remainder as 4, the numerator will be 4 and the denominator will be the same that is 5 as shown below:

14/5 = 2 4/5

Hence the fraction 14/5 written as a mixed fraction is equivalent to 2 4/5

Answer:

Value of 5×198 is:

990

Step-by-step explanation:

We have to find the value of  5 x 198 with the help of distributive property that includes multiplication and subtraction

Distributive property says that if a,band c are three numbers

then,  a(b-c)= ab-ac

5 x 198= 5(200-2)

           = 5×200 - 5×2

           = 1000-10

           = 990

Hence, Value of 5×198 is:

Answer:  The correct option is (C) [tex]\dfrac{1}{4}.[/tex]

Step-by-step explanation:  We are given to find the common ratio for the following geometric sequence :

64,   16,   4,   1,   .   .    .

We know that

if a(n) represents the n-th term of a geometric series, then the common ratio is given by

[tex]r=\dfrac{a(n+1)}{a(n)},~~~n=0,~1,~2,~~.~~.~~.[/tex]

For the given geometric sequence, we have

a(1) = 64,  a(2) = 16,  a(3) = 4,  a(4) = 1,  .  .  .

So, the common ratio r will be given by

[tex]r=\dfrac{a(2)}{a(1)}=\dfrac{a(3)}{a(2)}=\dfrac{a(4)}{a(3)}=~~.~~.~~.[/tex]

We have

[tex]\dfrac{a(2)}{a(1)}=\dfrac{16}{64}=\dfrac{1}{4},\\\\\\\dfrac{a(3)}{a(2)}=\dfrac{4}{16}=\dfrac{1}{4},\\\\\\\dfrac{a(4)}{a(3)}=\dfrac{1}{4},~~\cdots[/tex]

Thus, the required common ratio for the given geometric sequence is [tex]\dfrac{1}{4}.[/tex]

Option (C) is CORRECT.

Final answer:

The division of the complex numbers (3 - i) by (1 + 5i) results in the standard form -1/13 - 8/13i, by multiplying both the numerator and denominator by the conjugate of the denominator. The correct answer is option D.

Explanation:

To divide the complex number 3 - i by 1 + 5i, we should multiply numerator and denominator by the conjugate of the denominator to get rid of the imaginary part in the denominator:

(3 - i) * (1 - 5i) = 3 - 15i - i + 5i2

Since i2 = -1, it simplifies to:

3 - 16i - 5 = -2 - 16i

(1 + 5i) * (1 - 5i) = 1 - 5i + 5i - 25i2

Similarly, it simplifies to:

1 + 25 = 26

(-2 - 16i) / 26 = -2/26 - 16i/26

Simplify the fractions:

-1/13 - 8/13i

The standard form of the result is -1/13 - 8/13i, which corresponds to option D.

The rate of inflation from last year to this year is calculated by finding the 'change in CPI' which is then divided by the 'old CPI' and multiplied by 100 to convert it into percentage. The change in CPI is the new CPI minus the old CPI. By following the steps, we find that the rate of inflation is 10%.

To calculate the rate of inflation, we first need to determine the 'change in CPI', which will then be divided by the 'old CPI'. The formula is:

(New CPI - Old CPI) / Old CPI x 100%

The 'change in CPI' is the new CPI (this year's CPI) minus the old CPI (last year's CPI). This will be:

121 (this year's CPI) - 110 (last year's CPI) = 11

Now, we'll divide 'change in CPI' by old CPI, which is:

11 (change in CPI) / 110 (old CPI) = 0.1

To convert the value into percentage, we should multiply it by 100:

0.1 x 100 = 10

So, this year's rate of inflation is 10%.

Answer:

16 2/3

Step-by-step explanation:

The bicyclist's average speed was 16.67 miles per hour

The student asks about the average speed of a bicyclist who traveled for 1.5 hours and covered 25 miles. The average speed can be found using the formula v = d/t, which suggests speed (v) equals distance (d) divided by time (t). To solve for the bicyclist's average speed, we'll insert the given values into the formula.

Here's the step-by-step calculation:

Identify the given variables: d = 25 miles and t = 1.5 hours.

Substitute the values into the formula: v = 25 miles / 1.5 hours.

Calculate the quotient to find the average speed: v = 16.67 miles per hour (rounded to two decimal places).

Therefore, to find the bicyclist's average speed, divide the distance traveled, 25 miles, by the time spent, 1.5 hours, which yields an average speed of 16.67 miles per hour.

Final answer:

The Long family spent $38.62 for school supplies and $215.78 for new school clothes. To find the total amount spent, add the cost of school supplies and new school clothes. To calculate the sales tax, multiply the total amount spent by the sales tax rate.

Explanation:

To find the total amount spent, we need to add the cost of school supplies and new school clothes. The Long family spent $38.62 on school supplies and $215.78 on new school clothes, so the total amount spent is $38.62 + $215.78 = $254.40. Now, to calculate the sales tax, we need to find the percentage of the total amount spent. Let's assume the sales tax rate is 8%. To find the sales tax amount, we multiply the total amount spent by the sales tax rate as a decimal: $254.40 x 0.08 = $20.35.

Answer:

mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.

Step-by-step explanation:

The planet Mars has two moons Phobos and Deimos.

Mass of Phobos = 10.8 × 10¹⁵ Kilograms

Mass of Deimos = 2 × 10¹⁵ Kilograms

So the difference in the masses of the moons

= 10.8 × 10¹⁵ - 2 × 10¹⁵

= (10.8 - 2) × 10¹⁵

= 8.8 × 10¹⁵ Kilograms

Therefore, mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.
