Three less than three times a number is 5/6. What is one more than twice the number

dimaraw [331]

Answer:

32/9

Step-by-step explanation:

Translating the word problem into a symbolic equation yields:

3n - 3 = 5/6

Solve this for the number (n):

Multiplying both sides of this equation by 6 clears out the fraction term:

18n - 18 = 5

Adding 18 to both sides isolates 18n: 18n = 23

Then the number is n = 23/18, and:

one more than twice this number n is 2(23/18) + 1, or:

46/18 + 18/18, or 64/18, or (reducing this result)

32/9

Find the area of triangle jkl above if the vertices are j(2,2), k(3,5), and L(6,2)

tankabanditka [31]

Answer:

$Area=6\:units^2$

Step-by-step explanation:

Given the vertices $(x_1,y_1)=J(2,2)$ , $(x_2,y_2)=K(3,5)$ and

$(x_3,y_3)=L(6,2)$ . The area of triangle JKL is given by:

$Area=\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|$

We substitute the values to get:

$Area=\frac{1}{2}|2(5-2)+3(2-2)+6(2-5)|$

This simplifies to

$Area=\frac{1}{2}|2(3)+3(0)+6(-3)|$

$Area=\frac{1}{2}|6+0-18|$

$Area=\frac{1}{2}|-12|$

$Area=\frac{1}{2}*12$

$Area=6\:units^2$

Find mDCAˆ. the question says that the angle is 3x+19 the smaller arc is 91 and the bigger is 17x-3 it is one of those problems

valina [46]

Answer: Option C.

Step-by-step explanation:

Let as consider the below figure is attached below.

We know that angle between tangent and secant is half of difference of major and minor arcs.

$\angle ABC=\dfrac{arc(AD)-arc(AC)}{2}$

$3x+19=\dfrac{17x-3-91}{2}$

Multiply both sides by 2.

$6x+38=17x-94$

$38+94=17x-6x$

$132=11x$

Divide both sides by 11.

$12=x$

The value of x is 12.

$arc(AD)=17(12)-3$

$arc(AD)=204-3$

$arc(AD)=201^{\circ}$

Now,

$arc(DCA)=360^\circ-arc(AD)$

$arc(DCA)=360^\circ-201^{\circ}$

$m\widehat {DCA}=159^{\circ}$

Therefore, the correct option is C .
