Answer:

6 − 4 x = 6 x − 8 x − 2 Since x

is on the right side of the equation, switch the sides so it is on the left side of the equation.

6 x − 8 x − 2 = 6− 4 x Subtract 8 x from 6 x . − 2 x − 2 = 6 − 4 x

Move all terms containing x

to the left side of the equation.

Tap for fewer steps...

Add 4 x

to both sides of the equation.

− 2 x − 2 + 4 x = 6 Add − 2 x and 4 x . 2 x − 2 = 6

Move all terms not containing

x to the right side of the equation.

Tap for fewer steps...

Add 2

to both sides of the equation.

2 x = 6 + 2 Add 6 and 2 . 2 x = 8

Divide each term by

2 and simplify.

Tap for fewer steps...

Divide each term in

2 x = 8 by 2 . 2 x 2 = 8 2 Cancel the common factor of

2 . Tap for more steps...

x = 8 2 Divide 8 by 2 .

x = 4

Let S = {4, 6, 8} and T = {3, 5, 7}. Use the set roster notation to write each of the following sets, and indicate the number of

allochka39001 [22]

Answer:

See explanation

Step-by-step explanation:

Definition: $S\times T=\{(s,t)|s\in S,\ t\in T\}$

Given: $S=\{4,6,8\},\ T=\{3,5,7\}$

1. Find $S\times T:$

$S\times T=\{(4,3),(4,5),(4,7),(6,3),(6,5),(6,7),(8,3),(8,5),(8,7)\}$

There are 9 elements.

2. Find $T\times S:$

$T\times S=\{(3,4),(3,6),(3,8),(5,4),(5,6),(5,8),(7,4),(7,6),(7,8)\}$

There are 9 elements.

3. Find $S\times S:$

$S\times S=\{(4,4),(4,6),(4,8),(6,4),(6,6),(6,8),(8,4),(8,6),(8,8)\}$

There are 9 elements.

4. Find $T\times T:$

$T\times T=\{(3,3),(3,5),(3,7),(5,3),(5,5),(5,7),(7,3),(7,5),(7,7)\}$

There are 9 elements.

Given points (0,0) and (3,6), find the point which partitions the segment into 3:2.

sertanlavr [38]

Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts

Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)

Find one part of the share for each axes, we do
$\frac{x_1+x_2}{5} = \frac{0+3}{5}= \frac{3}{5} =0.6$
$\frac{y_1+y_2}{5}= \frac{0+6}{5}= \frac{6}{5}=1.2$

Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4

The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)

Correct answer: A

The difference of two numbers is 16 the greater number is five less than four times a small number find the two numbers

Elis [28]

Answer:

The numbers are 23 and 7

Step-by-step explanation:

1. Set up the equations

Let x = the greater number

and y = the smaller number. Then

(1) x - y = 16

4y = 4 times the smaller number and

4y - 5 = 5 less than 4 times the smaller number. Then

(2) x = 4y - 5

You have a system of two equations:

$\begin{cases}(1) & x - y = 16\\(2) & x = 4y - 5\end{cases}$

2. Solve the equations

$\begin{array}{lrcll}(3) & 4y - 5 - y & = & 16 &\text{Substituted (2) into (1)}\\& 3y - 5 & = & 16 &\text{Simplified}\\ & 3y & = & 21 &\text{Added 5 to each side}\\(4) &y & = & \mathbf{7} &\text{Divided each side by 3} \\& x - 7 & = & 16 & \text{Substituted (4) into (1)}\\& x& = & \mathbf{23} & \text{Added 7 to each side}\\\end{array}$

The larger number is 23; the smaller number is 7.

3. Check

$\begin{array}{rclcrcl}23 - 7& = & 16 & \qquad &23&=&4(7) - 5\\16 & = & 16 & \qquad &23& = &28 - 5\\&&& \qquad &23& = &23\\\end{array}$

OK.

In transaction (C) on 5/10, the Fees Earned account is a(n)

love history [14]

Answer:

(B) Revenue account which increases

Step-by-step explanation:

Hello, my dear friend, I am sure the question you are intending should be corrected as follows:

In transaction (C) on 5/10, the Fees Earned account is a(n) A. Expense account, which increases B. Revenue account, which increases C. Revenue account, which decreases D. Asset account, which decreases

If that is the case, then please note that whatever amount you earn, is an amount that will always increase. If you have no earnings, then nothing decreases nor decreases.
