In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10. What is the value of x?

Answers

Answer: The value of x= 18

Step-by-step explanation:

Given: In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10.

The sum of all angles of a triangle is 180°.

Therefore, in triangle EFG

∠E + ∠F +∠G= 180°

⇒ 8x-16 +x+8+ 2x-10 =  180

⇒ 11x-18= 180

⇒ 11x = 180+18

⇒11x=198

⇒ x= 18   [Divide both sides by 11]

Hence, the value of x= 18

Given:

The table of values.

v and x are in direct proportion.

To find:

The formula connecting v and x.

Solution:

(a)

v and x are in direct proportion.

[tex]v\propto x[/tex]

[tex]v=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

Putting v=13.6 and x=32.64, we get

[tex]13.6=k(32.64)[/tex]

[tex]\dfrac{13.6}{32.64}=k[/tex]

[tex]\dfrac{5}{12}=k[/tex]

Putting the value of k in (i), we get

[tex]v=\dfrac{5}{12}x[/tex]

Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].

(b)

Putting v=n and x=8.16, we get

[tex]n=\dfrac{5}{12}(8.16)[/tex]

[tex]n=3.4[/tex]

Therefore, the value of n is 3.4.

What are credit cards and their uses?

A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.


Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.

Answer:

[tex]y = \frac{7}{6} x[/tex]

Step-by-step explanation:

Slope-intercept form is

[tex]y = mx + b[/tex]

Where m = slope,

and b = y-intercept.

The problem states that the slope is [tex]\frac{7}{6}[/tex], and it also states that one point on the line is the origin. (0, 0)

Because the origin crosses the y-axis at point 0, we know that the y-intercept is 0.

All that's left to do is plug these values into the slope formula.

[tex]y = \frac{7}{6} x + 0[/tex]

We can then simplify the equation even more.

[tex]y = \frac{7}{6} x[/tex]

Which equation is equivalent to 10x+15y=−90 when it is solved for y? y=−23x−6 y=23x−6 y=−32x−6 y=32x−6

Answers

Answer:

Step-by-step explanation:

10x + 15y = -90

15y = -10x - 90

y = (-10/15)x - 90/15 = -⅔x - 6

The required equation is -(2/3)x - 6 which is equivalent to the given equation 10x + 15y = −90, which is the correct answer that would be option (A).

What is the equation?

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

The equation is given in the question

10x + 15y = -90

We have to determine whether the equation is equivalent to 10x+15y=−90 when it is solved for y

As per the given equation,

⇒ 10x + 15y = -90

Rearrange the term of variables and solve for y

⇒ 15y = -10x - 90

Divided by 15 into both sides of the above equation,

⇒ y = (-10/15)x - 90/15 =

Reduce the fraction to the simplest form,

⇒ y = -(2/3)x - 6

Therefore, the required equation is -(2/3)x - 6 which equivalent to given equation 10x + 15y = −90.
