Step-by-step explanation:

Tonya is twice Kevin's age. In three years, Tonya will be 17. And in another three years, Uncle Rob will be three times Tonya’s age.

Answers

Kevin is 7 years, Tonya is 14 years and uncle rob is 54 years

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Tonya is twice Kevin's age

In three years, Tonya will be 17.

t+3=17

t=14

tonya is now 14 years.

As Tonay is 2 times kevin

t=2k

Substitute t value in above equation.

14=2k

divide both sides by 2

7=k

kevin is 7.

And in another three years, Uncle Rob will be three times Tonya’s age.

17+3, rob is 3 times Tonya

20(3)=60 years.

60, that is in 6 years, so 60-6=54

Kevin is 7 years

Tonya is 14 years

unclerob is 54 years

Hence, Kevin is 7 years, Tonya is 14 years and uncle rob is 54 years

#SPJ3

t=age now of tonya
t+3=age in 3 years
t+3=17
minus 3
t=14

tonya is now 14
tonay is 2 times kevin
t=2k
14=2k
divide 2
7=k
kevin is 7



in another 3 years (3+3=6) so t+6, or 17+3, rob is 3 times tonya
20*3=60
60, that is in 6 years, so 60-6=54


kevin is 7
tonya is 14
uncle rob is 54

The altitude of an equilateral triangle is 18 inches. Find the length of a side

Answers

Let the length of equilateral triangle be x.

Each of the angle in an equilateral triangle is = 60°

The opposite to the 60° is the 18 inches. Hypotenuse is the side.

Sin 60° = 18 / Hypotenuse

Hypotenuse = 18 / Sin60°.                      Sin60° = √3 / 2

 x = 18 / (√3 / 2)

                      =   18 / √3  *  2/1 =  36 / √3

              x       = 36 / √3

 Rationalize the surd = 36 / √3  * (√3 / √3 ) = 36√3 / 3

                                   x = 12√3 ≈ 12 * 1.732 ≈ 20.784

Length of side, x = 12√3 ≈ 20.784 inches.

I would do this by X times g but first figure out what x is than to did his you have to figure out what what the answer is to what it equals and the answer to that is the same for the first expression than divide the answer by what x is and if it gives you g than that's your answer

Can you plz help me on this?

Answer:

B 2x-31 = -2x-31

Step-by-step explanation:

A is exactly the same on the left side as the right so it has infinite solutions

B 2x-31 = -2x-31

 Add 2x on each side

2x+2x-31 = -2x+2x-31

4x -31 = 31

Add 31

4x =62

This has one solution

C 2x+31 = 2x-31

Subtract 2x from each side

31 = -31

This is never true so it has no solutions

D 2x-2 = 2x-31

Subtract 2x from each side

-2 = -31

This is never true so it has no solutions

Answer:

B)

Step-by-step explanation:

2x - 31 = -2x - 31

4x = 0

x = 0

x = 0 is the only solution
