PLEASE HELPTH ME (MODERATORS STOP I REPEAT STOP REMOVING MY QUESTIONS BRO)

Answer:

X=75

Y=110

Step-by-step explanation:

A straight line is 180, so add the equations that make a line and set them equal to 180

x+20+x+10=180

Combine like terms

2x+30=180

Subtract 30 from both sides

2x=150

Divide by 2

X=75

Same for y

y+y-40=180

2y-40=180

Add 40 to both sides

2y=220

Divide by 2

Y=110

Divide (-3х + 4 + 18х^2 )by (5 + 6x)

Leokris [45]

Answer:

The division will be represented as:

$\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}$

Step-by-step explanation:

1) Let's find a number with a variable that multiplied by 6x gives as 18x². It will be 3x, because (6x+5)3x=18x²+15x.

Now, let's subtstract:

$(18x^{2}-3x+4)-(18x^{2}+15x)=-18x+4$

2) Let's find a number with a variable that multiplied by 6x gives as -18x. It will be -3, because (6x+5)(-3)=-18x-15.

Now, let's subtstract:

$(-18x+4)-(-18x-15)=19$

Therefore, the division will be represented as:

$\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}$

I hope it helps you!

Solve for n. then find the value of m for each value of n<br> 8n=-3m+1

Eva8 [605]

Basically, solve for n, then find aanother tha is solve for m

8n=-3m+1
divide both sides by 8
n=-3/8m+1/8

and find m
8n=-3m+1
minus 1 both sides
8n-1=-3m
divide both sides by -3
-8/3n+1/3=m
m=-8/3n+1/3
