3/4x - 2.25 -3/4 = 0

3/4x -2.25 = 3/4

x - 2.25 = (3/4)/(3/4) or just 1

x = 2.25 + 1

x = 3.25

Mike spent half of his allowance playing acrade games his parents let him wash the gutters for 5.80 if he ended with 12.20 what is his weekly allowance

Answers

Answer:

Weekly allowance (W) = 12.80

Step-by-step explanation:

Given:

Ended amount = 12.20

Amount for guitar wash = 5.80

Find:

Weekly allowance (W)

Computation:

W + 5.80 - W/2 = 12.20

W + 5.80 - 0.5W = 12.20

0.5 W = 6.4

Weekly allowance (W) = 12.80

Line m passes through points (10, 10) and (2, 1). Line n is perpendicular to m. What is the
slope of line n?

Answers

Answer:

-8/9

Step-by-step explanation:

my work is in the picture above. lmk if you'd like me to explain more

The slope of line [n] would be -8/9.

What is the general equation of a Straight line?

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

(y - y₁) = m(x - x₁)                               {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁)     {Two point - slope form}x/a + y/b = 1                                        {intercept form}x cos(β) + y sin(β) = L                        {Normal form}

We have line [m] passes through points (10, 10) and (2, 1).

We can write the equation of line [m] as follows.

slope of line [m] = a = (1 - 10)/(2 - 10) = -9/-8 = 9/8

a = 9/8

slope of line [n] -

m[n] x a = - 1

m[n] = -1/a

m[n] = -8/9

Therefore, the slope of line [n] would be -8/9.

Step-by-step explanation:

The formula of a midpoint of the segment AB:

We have A(7, -2) and B(1, -10). Substitute:

[tex]M_{AB}\left(\dfrac{7+1}{2};\ \dfrac{-2+(-10)}{2}\right)\\\\M_{AB}\left(\dfrac{8}{2};\ \dfrac{-12}{2}\right)\\\\M_{AB}(4;\ -6)[/tex]

Midpoint = average of x and y

Draw triangle ABC by first drawing segment BC six inches long. Then draw a 60° angle at vertex B and a 60° angle at vertex C. Extend the segments so that they intersect at point A.

Answers

Answer:

Step-by-step explanation:

Given that segment BC is the base of the triangle, this drawing shows that triangle ABC is an equilateral triangle.

Since;

<B = <C = 60°

Then,

<A + <B + <C = [tex]180^{o}[/tex]

<A + 60° + 60° = [tex]180^{o}[/tex]

<A = [tex]180^{o}[/tex] - [tex]120^{o}[/tex]

    = 60°

Thus,

AB = BC = AC = 6 inches

The construction is attached to this answer.

Step-by-step explanation:

Since the dilatation is centred at the origin, then multiply each of the coordinates of the point by the scale factor, that is

Determine the mass of an object, if it requires a force of 6,000 kg: m/s2 to accelerate at the rate of 2 m/s^2

Answers

Answer:

The answer is 3000 kg

Step-by-step explanation:

The mass of an object can be found by using the formula

[tex]m = \frac{f}{a} \\ [/tex]

f is the force

a is the acceleration

From the question we have

[tex]m = \frac{6000}{2} \\ [/tex]

We have the final answer as

3000 kg

Hope this helps you

[tex] \boxed{ \red{AnswEr:-}}[/tex]

Mass = 3000 kg

GivEn :-

Force = 6000 kg • m/s^2Acceleration = 2 m/s^2

To Find :-

The value of mass

Solution :-

From Newton's 2nd law of motion we get the equation,

[tex]{ \boxed{ \red{ \sf{F =

m \times a}}}}[/tex]

where,

F = Force m = mass of the objecta = acceleration

[tex] \implies \sf \: m = \dfrac{F}{a} [/tex]

Putting the values,

[tex] \implies \sf \: m = \dfrac{6000}{2} [/tex]

[tex] \implies \red{\sf \: m = 3000}[/tex]

Therefore, mass of the object = 3000 kg

Bethany scored 5 more points than Adam.
They scored a total of 72 points.
Find the number of points that Adam, Bethany and Charles each scored.

Answers

....................

Points scored by Adam, Bethany and Charles are 25, 17 and 30 respectively.

What is algebra?

Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.

Given that,

Adam scored 8 more points than Charles,

And Bethany scored 5 more points than Adam.

Also, total score is 72.

Let points scored by Adam is x,

Then point scored by Charles = x-8,

And point scored by Bethany = x+5.

Since, total score = 72

x + x-8 + x+5 = 72

3x - 3 = 72

3x = 75

x = 25

Points scored by Adam is x = 25,

Point scored by Charles = x-8 = 17,

And point scored by Bethany = x+5 = 30.
