Step-by-step explanation:

1. 5/3x-3=2/3x+12

x=15 once you combine like terms

2. 5x+35-3x+12=7x+2

2x+47=7x+2

5x=45

x=9

3. 12x+20-3=9x-7

12x+17=9x-7

3x=-24

x=-8

Help me solve this please 33+15w=3w-w+4w
hichkok12 [17]

Answer:

33+15w=3w-w+4w

33+15w - 15w=3w-w+4w -15w

33 = 2w + 4w -15w

33 = 6w -15w

33 = -9w

33/9 = -9/9w

3.66 = w

Step-by-step explanation:

33+15w=3w-w+4w

33+15w - 15w=3w-w+4w -15w

33 = 2w + 4w -15w

33 = 6w -15w

33 = -9w

33/9 = -9/9w

3.66 = w

ohan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. which explains whether his solut
klio [65]
-2 | 8-x| - 6 = -12...add 6 to both sides
-2 |8-x| = -12 + 6
-2 |8-x| = - 6...divide both sides by -2
|8-x| = -6/-2
|8-x| = 3

8 - x = -3          -(8 - x) = -3
-x = -3-8           -8 + x = -3
-x = -11              x = -3 + 8
x = 11                x = 5

A monitor measures 10.6 inches by 16.8 what is the length of the diagonal
Ludmilka [50]

Step-by-step explanation:

We will use pythagoras' Theorem for this question

{c}^{2}  =  {a}^{2}  +  {b}^{2}

where c is the longest side (in this case, the diagonal)

a and b are the 2nd and 3rd longest side (interchangeable)

given a = 10.6, b = 16.8,

{c}^{2}  =  {10.6}^{2}  +  {16.8}^{2} \\  {c}^{2}   = 112.36 + 282.24 \\  {c}^{2}  = 394.6 \\ c =  \sqrt{394.6} \\  =  \frac{ \sqrt{9865} }{5}  inches
