Answer:

Step-by-step explanation:

x+2/3=2

multiply by 3

3x+2=6

3x=6-2

3x=4

x=4/3

if it is (x+2)/3=2

multiply by 3

x+2=6

x=6-2=4

Answer:

[tex]x=\frac{4}{3}[/tex]

Step-by-step explanation:

[tex]x+\frac{2}{3}=2[/tex]

to find the value of x we subtract 2/3 on both sides

[tex]x+\frac{2}{3}-\frac{2}{3}=2-\frac{2}{3}[/tex]

taking LCM AS 3

[tex]x=\frac{2*3}{1*3}-\frac{2}{3}[/tex]

[tex]x=\frac{6}{3}-\frac{2}{3}[/tex]

[tex]x=\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

(3 + 1)/(-2 - 4) = 4/-6 = -2/3

y + 1 = -2/3(x -4)

y + 1 = -2/3x + 8/3

y + 3/3 = -2/3x + 8/3

y = -2/3x + 5/3

2x + 3y - 5 = 0 is the standard form

The required equation of the line that passes through (4, -1) and (-2, 3) is 2x+3y-5 = 0

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, A line is passing through points (4, -1) and (-2, 3)

We know that, the equation of a line passing through two points is given by, (y-y₁) = (y₂-y₁)/(x₂-x₁)(x-x₁)

y+1 = (3+1)/(-2-4)(x-4)

y+1 = -2/3(x-4)

3y+3 = -2x+8

2x+3y-5 = 0

Hence, The required equation of the line that passes through (4, -1) and (-2, 3) is 2x+3y-5 = 0

(x+3) *x = 2x*(6x-6)

Divide each side by x

x+3 = 2(6x-6)

Distribute

x+3 = 12x-12

Subtract x from each side

x+3-x = 12x-x-12

3  = 11x-12

Add 12 to each side

3+12 = 11x-12+12

15 = 11x

Divide each side by 11

15/11 =x

Answer:

15/11

Step-by-step explanation:

(x + 3) *x = 2x * (6x - 6)

x^2 + 3x = 12x^2 - 12x

x^2 - 12x^2 = - 12x - 3x

- 11x^2 = - 15x

11 x * x = 15 * x

Like terms cancel out

11x = 15

= 15/11

Answer:

30° and 110°

55° and 85°

70° and 70°

Step-by-step explanation:

Given that:

[tex]\angle B = 90^\circ[/tex]

To find the possible values for the other two angles [tex]\angle A\ and\ \angle C[/tex].

Property of a triangle is that the sum of all three angles is always equal to [tex]180^\circ[/tex].

OR

[tex]\angle A +\angle B +\angle C = 180^\circ\\\Rightarrow \angle A + 40^\circ + \angle C = 180^\circ\\\Rightarrow \angle A + \angle C = 180^\circ - 40^\circ\\\Rightarrow \angle A + \angle C = 140^\circ[/tex]

So, the sum of [tex]\angle A\ and\ \angle C[/tex] should be [tex]140^\circ[/tex]. We can select our answers according to this condition.

Option 1: 20° and 30°: the sum is [tex]50^\circ \neq 140^\circ[/tex] hence, not correct.

Option 2: 30° and 110°: the sum is [tex]140^\circ[/tex] hence, correct.

Option 3: 55° and 85°: the sum is [tex]140^\circ[/tex] hence, correct.

Option 4: 60° and 90°: the sum is [tex]150^\circ \neq 140^\circ[/tex] hence, not correct.

Option 5: 70° and 70°: the sum is [tex]140^\circ[/tex] hence, correct.

Hence, the possible answers can be:

30° and 110°

55° and 85°

70° and 70°

Step-by-step explanation:

You have to multiply both terms from the first one by both term in the second on, it'll look like this:

[tex](x-9)*(2x-7)=(x*2x)+(x*-7)+(-9*2x)+(-9*-7)\\(x-9)*(2x-7)=(2x^2)+(-7x)+(-18x)+(63)[/tex]

Once you combine like terms it'll be the final answer:

Answer:

Step-by-step explanation:

The geometric mean has a set up it must follow in order to "work". If you look at #3, x is a side of the smaller triangle that has a base of 3, but it's also a side of the large triangle that has a base of 3 + 8 which is 11.  That means that x is your geometric mean. Setting up the geometric mean will look like this:

[tex]\frac{3}{x}=\frac{x}{11}[/tex]

where x is the geometric means and the 3 and the 11 (the positions they are in) are the geometric extremes.

Now we cross multiply to solve for x:

[tex]x^2=33[/tex] and

[tex]x=\sqrt{33}[/tex]

That's the length of x in #3.

For #4, x is the side of the small triangle with the base of 7 and it's also the side of the large triangle with the base of 7 + 13 which 20. That means that x is the geometric mean. Setting up like above:

[tex]\frac{7}{x}=\frac{x}{20}[/tex] and

[tex]x^2=140[/tex] so

[tex]x=\sqrt{140}[/tex]

Answer:

The distance between park and museum is 12km.

Step-by-step explanation:

Given that the map shows 1cm represents 3km. In this question, the distance between park and museum is 4cm so in order to find the real-life distance, you have to multiply by 4 :

[tex]1cm = 3km[/tex]

[tex]4cm = 3km \times 4[/tex]

[tex]4cm = 12km[/tex]

Hence, the real-life distance between the park and the museum is [tex]12km[/tex].

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Here is a map of a town.The map shows a centimetre ruler [tex]1[/tex] cm represents [tex]3[/tex] km.

In a map it is mentioned that [tex]1[/tex]cm which represents the [tex]3[/tex] km. So, the distance between park and museum is

[tex]1+3=4[/tex]cm

So for the real-life distance, we multiply by [tex]4[/tex]

then,

[tex]1cm=3km\\\\4cm=3(4)km\\\\4cm=12km[/tex]

Hence, the real-life distance between the park and the museum is [tex]12km[/tex].

Answer:

v = -1

Step-by-step explanation:

First, you will need to solve it step-by-step:

(4v − 9)(1 + v) = 0

Next, you need to simplify both sides of the equation:

4v(2) − 5v − 9 = 0

Now, factor the left side of equation:

(4v − 9)(v + 1) = 0

The last thing you need to do is to set all of the factors to equal to zero:

4v − 9 = 0 or v + 1 = 0

So, that means that you answer:

v=9/4 or in your case, v = −1

Answer:

The angle is 53.13 degrees

Step-by-step explanation:

In this question, we are to calculate the angle to which a ladder is to be set to get to a window.

Now, looking at this, we can picture a triangle where the length of the ladder represents the the hypotenuse while the angle we are considering makes the height of the room from the floor.

Please check attachment for picture of triangle

Since we are considering the hypotenuse and the opposite, the mathematical term we would be using is the sine.

Sine of an angle = length of opposite/length of hypotenuse

Sine angle = 8/10

since angle = 8/10

angle = arc sin 0.8

angle = 53.13 degrees

Answer:

Step-by-step explanation:

The number of gift baskets Nikki can make varies directly with the amount of time she spends making the baskets .

Let n be the number of baskets and let t be the mount of time it takes to make the basket. This means that:

n α t

=> n = kt

where k = constant of proportionality

She can make 4 baskets in every 1/2 hour.

This means that:

4 = k * 1/2

=> k = 4 * 2 = 8 baskets per hour

The time is now 5 hours (t = 5). Therefore:

n = 8 * 5 = 40 baskets

She can make 40 baskets in 5 hours.
