Divide 15 in the ratio 3:2

1 answer:

7 0

One way of approaching this would be to add up 3 and 2, obtaining 5, and then multiplying 15 by 3/5:

15(3/5) = 9

Then write and solve the equation of ratios:

3 9
-- = ------
2 x

Then 3x=18, and x=6. Thus, 15 divides into 9 and 6, which has the ratio 3:2.

Find the measure of arc YX in the inscribed angle C in the circle below

klasskru [66]

Answer:

Arc YX = 104°

Step-by-step explanation:

Arc YX + Arc YZ + Arc XZ = 360° (full circle = 360°)

Substitute

Arc YX + 110° + 146° = 360°

Arc YX + 256° = 360°

Arc YX = 360° - 256°

Arc YX = 104°

12x−5y=−20 y=x+4 x=x=x, equals y=y=y, equals

aksik [14]

Answer:

The solution is (0, 4)

Step-by-step explanation:

Please pay attention to the first two equations and drop the last two:

12x−5y=−20 y=x+4 x=x=x, equals y=y=y should ideally be:

12x−5y=−20

y=x+4

Let's find x. Substitute x + 4 for y in the first equation, obtaining:

12x - 5(x + 4) = -20

Carrying out the indicated multiplication, we get:

12x - 5x - 20 = -20, or 7x = 0

If x = 0 then y must be 0 + 4, or 4.

The solution is (0, 4)
