A triangle has one angle measuring 3X degrees a second angle measures 2X +20°

Lena [83]3 years ago

Answer : x = 20

Explanation :
3x + 2x +20 + 4x - 20 = 180

(3+2+4=9)

9x + 20 - 20
The 20s cancel each other out because one is positive and the other is negative

9x = 180

9x/9 = 180/9

X = 180 divided by 9

X = 20

Slope =<br> ; y-intercept = -3
Goshia [24]

Question is incomplete Let assume the Slope = 2

Answer:

Therefore the Equation of line is

y=2x -3

Step-by-step explanation:

Given:

Slope = 2 ( Assumption )

y-intercept = -3

To Find:

Equation of Line in Slope-intercept form

Solution:

Equation of Line in Slope-intercept Form is given as

y=mx+c

Where,

m=Slope\\c=y-intercept

So, substituting Slope =2 and y-intercept = -3 in above we get

y=2\times x -3 Which is the Required Equation of line

Therefore the Equation of line is

y=2x -3

10(1+3x)=-20 and -5x-8(1+7x)=-8 <br> With steps
SOVA2 [1]

(1)

10(1+3x)=-20

Cross multiply.

10+30x=-20

Isolate x on one side. So you would subtract 10 on each side. and one side will cross each other out. leaving you with,

30x=-20-10

Subtract 10 from -20.

30x=-30

Divide each side by 30 to get x.

30x÷30=-30÷30

Therefore,

x=-1

(2)

-5x-8(1+7x)=-8

Cross multiply -8(1+7x)

-5x-8-56x=-8

Isolate all x's on one side. So you would add 8 on each side. and one side will cross each other out. leaving you with,

-5x-56x=-8+8

Add 8 to -8.

-5x-56x=0

Subtract -56x from -5x

-61x=0

Divide each side by -61

-61x÷-61=0÷-61

Therefore,

x=0
