Solve for x:2/5 (x - 2) = 4x

Answers

Answer 1

Answer:

x= -2/9

Step-by-step explanation:

2(x-2)/5=4x

2(x-2)=4x*5

2(x-2)=20x

x-2=20x/2

x-2=10x

-2=10x-x

9x= -2

x= -2/9

Step-by-step explanation:

£50 is divided between Krutika, Natasha & Richard so that Krutika gets twice as much as Natasha, and Natasha gets three times as much as Richard. How much does Krutika get?

Answers

Answer:

£30

Step-by-step explanation:

→ Model the situation in terms of x

Richard = x, Natasha = 3x and Krutika = 6x

→ Now put the values into ratio form

6x : 3x : x = 50

→ Collect the x terms

10x = 50

→ Divide both sides by 10 to isolate

x = 5

→ Substitute x = 5 into Krutika

6 × 5 = 30

Answer:

£30

Step-by-step explanation:

Let's break down the information given to help us find how much Krutika gets.

"Natasha gets three times as much as Richard" - We can express the value that Natasha gets as [tex]3r[/tex] in terms of what Richard gets.

"Krutika gets twice as much as Natasha" - We can express this as [tex]2(3r)[/tex] which equals [tex]6r[/tex].

We know that the total money is £50, so we can write the equation:

[tex]r+3r+6r=50[/tex]

[tex]10r = 50[/tex]

[tex]r=5[/tex]

∴ Richard gets £5.

Since the money Krutika gets can be expressed as [tex]6r[/tex]:

[tex]6(5) = 30[/tex]

∴ Krutika gets £30.

A rectangular computer monitor is measured by the length and width of its display resolution. Three different monitors are described below. Monitor A has a display resolution of 640 pixels by 480 pixels. Monitor B has a display resolution of 800 pixels by 600 pixels. Monitor C has a display resolution of 1,280 pixels by 800 pixels. Which of the monitors are similar, based on their display resolution

Answers

Answer: Monitors A and B

Step-by-step explanation:

The similar monitors based on display resolution are those with similar ratios.

Take the ratios to their simplest forms to see which are similar.

Monitor A

= 640 : 480

= 16 : 12

= 4 : 3

Monitor B

= 800 : 600

= 8 : 6

= 4 : 3

Monitor C

= 1,280 : 800

= 32 : 20

= 8 : 5

Monitors A and B are similar as they have the same display ratio.

Using a layaway plan, Bill bought a set of golf clubs for $1700. He has 6 months to pay off his balance after paying a down payment. The store does not charge a fee for their program. If Bill makes payments of $201 a month, how much did he need to use as a down payment in order to pay for the clubs

Answers

Answer:

$494

Step-by-step explanation:

Given that:

Cost of golf club = $1700

Number of months taken to balance payment after down payment = 6 months

Amount paid per month = $201

The down payment made :

Cost of golf clubs - (monthly payment * number of months)

$1700 - ($201 * 6)

$1700 - $1206

= $494

Hence, the downpayment made = $494

The temperature in Quebec City was 5 degrees Celsius at 4 pm. By midnight, the temperature dropped 15 degrees. A number line has points negative 20, blank, A, B, 0, 5, C, blank, D. Which point is a representation of the colder midnight temperature in degrees Celsius?

Answers

Answer: Point A

Step-by-step explanation:

The temperature at midnight is;

= 5 - 15

= -10°C

Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.

With point A being -10°C, it represents the colder midnight temperature.

Answer:

Point A

Step-by-step explanation:

We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).

We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

solve for x- 5(x+4)=30​

Answers

Answer: x= -12.5

Step-by-step explanation:

Start with distributing-5(x+4) or you get

x-5x-20=30

Add x and -5x to get -4x

Thank you add 20 to each side and get

-4x = 50

Divide by -4 on each side to get x=-12.5

Answer:

x=-25/2 is the answer.

Step-by-step explanation:

Below are the steps for solving the equation:

Step 1: Simplify, combine like terms, and distribute:

x−5(x+4)=30

x+(−5)(x)+(−5)(4)=30

x+−5x+−20=30

(x+−5x)+(−20)=30

−4x+−20=30

−4x−20=30

Add 20 to each side:

−4x−20+20=30+20

−4x=50

Divide each side by -4:

-4x/-4=50/-4

x=-25/2, which is -12.5 as a decimal.

So, your answer is x=-25/2 as a fraction, which is also -12.5 as a decimal.

Write an equation in point slope form of the line that passes through the point (2,-8) and had a slope of 4

Answers

Point slope: y - y1 = m(x - x1)
Plug those in
Solution: y + 8 = 4(x - 2)

The equation of a line in point-slope form is  (y + 8) = 4(x - 2).

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A line passes through the point (x₁, y₁) ⇒ (2,-8) and had a slope of 4.

We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).

∴ The equation of this line is (y + 8) = 4(x - 2).
