I think it’s -6/5 because you need to get the same denominator which you would multiply 3 on the left top and bottom & the right by 5 top and bottom. You get -30/15 but you simply and get -6/5

Answer:

-30/15 or -2

Step-by-step explanation:

2+8 = 10

3+2 = 5

14-2 = 12

4-1 = 3

10/5 - 12/3

(Find GCF)(GCF = 15)(5 times 3)

30/15 (10/5 times 3)

60/15 (12/3 times 5)

30/15 - 60/15 = -30/15 --> -2(simplified to 2)

The ratio of the measure of the vertex angle to the base angle of an isosceles triangle is 8:5. Find the measure of the vertex a
Pie

Answer:

Step-by-step explanation:

The two base angles are equal.

The vertex angle is 8x

The two base angles are 5x + 5x

The sum of all three angles = 180 degrees (all triangles make 180 degrees when their interior angles are added).

5x + 5x + 8x = 180

18x = 180

x = 180/18

x = 10

Therefore the vertex angle is 8*10 = 80 degrees

One of the base angles = 10* 5 = 50 degrees

The other base angle = 50 because the triangle is isosceles.

What two integers have a sum of -31 and a difference of -55?
nekit [7.7K]

Answer:

Integer 1 is x

Integer 2 is y

x + y = -31

x - y = -55

Add:

2x = -86

x = -43

Substitute:

-43 + y = -31

y = 12

Therefore, the two integers are: 12 and -43

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6? Drag each choice into t
sesenic [268]

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?

Parallel, slope is the same, perpendicular slope is opposite and reciprocal

so

line n, with slope −6 , same slope -----> Parallel

line p, with slope 1/6 , opposite and reciprocal  -----> Perpendicular

line q, with slope −1/6 , -----> Neither

line  m, with slope 6, -----> Neither
