Inga [223]

None of the options give the same fees for a session of x hours.

Given,
x + 20/2 = 3x
when two tutoring services with different rate plans charge the same fees for a session of x hours.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements.

x + 20/2 = 3x
x + 10 = 3x

A) x= 10
10 + 10 = 3*10
20 ≠ 30

B) x=4
4 + 10 = 3 * 4
14 ≠ 12

C) x= -14
-14 + 10 = 3 * -14
-4 ≠ 42

D) x=-17
- 17 + 10 = 3 * - 17
-7 ≠ -51

Here, none of the options give the same fees for a session of x hours.

Thus, none of the options give the same fees for a session of x hours.

Jim sells used drones for 70% of the original manufacturer's purchase price of a new drone. Jim also sells new drones for 15% mo

adell [148]

The function for the amount saved if they purchase a used drone rather than a new drone from Jim's store is f(x) = 0.45x

He sells used drones at 70% of the price (x).

So, the selling price of a used drone is:

$\mathbf{Used = 70\% \times x}$

Express percentage as decimal

$\mathbf{Used = 0.7 \times x}$

$\mathbf{Used = 0.7x}$

Also, he sells new drones at 15% more of the price (x).

So, the selling price of a new drone is:

$\mathbf{New= (1 + 15\%) \times x}$

Express percentage as decimal

$\mathbf{New= (1 + 0.15) \times x}$

$\mathbf{New= 1.15 \times x}$

$\mathbf{New= 1.15x}$

The amount saved is the difference between the prices of the drones.

So, we have:

$\mathbf{Saved =New - Old}$

This gives

$\mathbf{Saved =1.15x- 0.7x}$

Subtract

$\mathbf{Saved =0.45x}$

Express as a function

$\mathbf{f(x) = 0.45x}$

Hence, the function for the amount saved is f(x) = 0.45x

svp [43]

He solved 30 questions.
He solved one question in one minute.
This if he continued at the speed and there are 40 minutes to solve the test and he leaves 10 minutes earlier. He is left with 30 minutes and one minutes per question . Therefore, he solved 30 question.

Heidi solved the equation 3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below: 3x + 12 + 2 = 2 + 5x – 20 3x + 14 = 5x – 18 14 = 2x

MArishka [77]

Given equation: 3(x + 4) + 2 = 2 + 5(x – 4).

<em>First step is to distribute 3 on left side and 5 on right side of the equation,</em> we get

3x + 12 + 2 = 2 + 5x – 20

<em>Second step is combining like terms, 12+2=14 and 2-20=-18.</em>

We get

3x +14 = 5x -18.

<h3>Third step, we need to get rid 18 from right side and 3x from left side.</h3>

<em>Adding 18 on both sides and subtracting 3x from both sides</em>, gives

32 = 2x.

<h3>Fourth step , we need to get rid 2 from right side from 2x.</h3>

<em>We need to divide both sides by 2</em>, we get

16=x.
