7+n=−5 18=−3y−6 3/5x=18

Keith_Richards [23]

Answer:

1) n=-12

2) y=-8

3) x= 1/30

Step-by-step explanation:

1) 7+n=-5

7+n-7=-5-7

n=-12

2) 18=-3y-6

-3y-6=18

-3y-6+6=18+6

-3y=24

-3y/-3 = 24/-3

y= -8

3) 3/5x=18

3/15 X 5x= 18 X 5x

3=90x

90x/90= 3/90

x= 1/30

Y=<br> Pls help solve for

miss Akunina [59]

Answer:

$y=39\degree$

Step-by-step explanation:

The given triangle is a right angle triangle .

The known sides of the triangle that is opposite to angle y is 8 units while the side adjacent is 10 units.

The value of y can be calculated using the tangent ratio.

$\tan(y)=\frac{8}{10}$

We solve for y to get,

$y=arctan(\frac{4}{5})$

We evaluate to obtain,

$y=38.66$

$y=39\degree$ to the nearest degree

Point R lies on the directed line segment from L (-8,-10) to M (4,-2) and partitions the segment in the ratio 3 to 5. What are t

Dvinal [7]

Answer:

R = (- 3.5, - 7 )

Step-by-step explanation:

Using the Section formula

$x_{R}$ = $\frac{3(4)+5(-8)}{3+5}$ = $\frac{12-40}{8}$ = $\frac{-28}{8}$ = - 3.5

$y_{R}$ = $\frac{3(-2)+5(-10)}{3+5}$ = $\frac{-6-50}{8}$ = $\frac{-56}{8}$ = - 7

Thus coordinates of R = (- 3.5, - 7 )
