hi <3

lets call the unknown number 'x' for now and form an equation from what we know

1/3(x-9) = 15

now multiply both sides by 3

x - 9 = 45

add 9 to both sides

x = 54

hope this helps :)

Answer:

Look in explanation

Step-by-step explanation:

I will assume that you're trying to solve for "x".

For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.

Now, 131 = 5x+1

        -1            -1

         130 = 5x

         /5      /5

Now, we isolate the x to get x=26.

Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.

Now, combine the like terms to get 11x+15=180 so we now isolate x.

                                                              -15   -15

                                                            11x=165

                                                            /11    /11

                                                               x=15

Now, try the rest and set the terms to 180.

5x+1+8+4x=180

2x+1+x-10=180

6+x+5x=180

x+2+153=180(This is similar to #1)

Hence 2/7>1/21

Answer:

First equation

from definition of acceleration:

[tex]a = \frac{change \: in \: velocity}{time} \\ \\ a = \frac{v - u}{t} \\ \\ at = v - u\\ { \boxed{v = u + at}}[/tex]

Second equation

from displacement:

[tex]s = (average \: velocity) \times time \\ s = ( \frac{v + u}{2} ) \times t \\ \\ 2s = (v + u)t[/tex]

but v is u + at :

[tex]2s = \{(u + at) + u \} \times t \\ \\ 2s = (2u + at)t \\ 2s = 2ut + {at}^{2} \\ s = \frac{2ut}{2} + \frac{a {t}^{2} }{2} \\ \\ { \boxed{s = ut + \frac{1}{2} {at}^{2} }}[/tex]

third equation

from displacement:

[tex]s = ( \frac{v + u}{2} )( \frac{v - u}{a} ) \\ \\ 2as = (v + u)(v - u) \\ 2as = {v}^{2} - {u }^{2} \\ \\ { \boxed{ {v}^{2} = {u}^{2} + 2as }}[/tex]

s » displacement

v » final velocity

u » initial velocity

a » acceleration

t » time

Answer:

x= 2

Step-by-step explanation:

3x – 5 = 1

Add 5 to each side

3x – 5+5 = 1+5

3x = 6

Divide by 3

3x/3 = 6/3

x= 2

Answer:

[tex]3x - 5 = 1 \\ 3x = 1 + 5 \\ 3x = 6 \\ x = \frac{6}{3} \\ x = 2 \\ thank \: you[/tex]

Answer:

  130°

Step-by-step explanation:

The angle sum theorem applies.

  ∠WXY = ∠WXZ +∠ZXY

  ∠WXY = 110° +20°

  ∠WXY = 130°

Answer:

JH = 15

Step-by-step explanation:

KJ = 10

KI = 14

IH = 11

JH = ?

In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:

JH = JI + 11

In order to find JI, we need to subtract KJ from KI. Here's the equation:

14(KI) - 10(KJ) = JI

14 - 10 = 4

JI = 4

Now we plug in the numbers from our first equation:

JH = JI + 11

JH = 4 + 11

JH = 15

Step-by-step explanation:

The mid value of 3 and -5 is -1 because both x-coordinates are 4 units away.

The mid value of -2 and -6 is -4 because both y-coordinates are 2 units away.

Answer:

y = -3x - 4

Step-by-step explanation:

-3x - y = 4

~Add 3x to both sides

-y = 4 + 3x

~Divide -1 to everything

y = -4 - 3x

~Reorder

y = -3x - 4
