To start you need to get rid of the denominator so you add -4 by 8 to get 4 then multiply both sides by 4 to remove the denominator giving you -8= 5-y1. After that subtract 5 from both sides giving you -13= -y1, dividing by -1 you then get y1= 13

20/12=15/x find x plz help

Ganezh [65]

Answer:

$x = 9$

Step-by-step explanation:

To find x, we first have to solve the equation given in the question:

$\frac{20}{12} = \frac{15}{x}$

$20x = 15 \cdot 12$

$x = \frac{180}{20}$

$x = 9$

Therefore, x = 9.

Hope this helped!

Without graphing, classify the following system as independent, dependent, or inconsistent. y=-3x+4 and 6x+2y=8

forsale [732]

Answer:

Dependent

Step-by-step explanation:

$y=-3x+4$ and $6x+2y=8$

Lets solve the second equation for y and then substitute it in first equation

$6x+2y=8$

Subtract 6x on both sides

$2y=-6x+8$

Divide by 2 on both sides

$y=-3x+4$

Now we plug it in first equation for y

$-3x+4=-3x+4$

Add 3x on both sides

$4=4$

Both sides are same, they are equal. the system has infinite solutions.

They are said to be dependent

I’ll give you best answer and a thanks plsplspls help i’m legit freaking out i keep getting decimals

First, find R angle at TRS = 180-(10x+13)
then you know that total angles of a triangle is 180 so
TRS+RST+STR
180-(10x+13) + 8x+1 + 34 = 180
180-10x-13+8x+1+34 = 180
-13+1+34 = 10x-8x
22 = 2x
then x = 11
