Mathematics
1 answer:
Effectus [21]4 years ago
3 0

Answer:

B y is 3/4 of (x+y)

Step-by-step explanation:

a : is the same thing as a division sign or a fraction bar

so 1 : 3 = 1/3

this ratio says that for every 1 of x, there are 3 y's.

so 1x = 3y or y = 1/3x

x = 1; y = 3

x + y = 4

y / (x+y)

3 / 4

y is 3/4 of (x+y)

Rama09 [41]

Answer:

x = 7

Step-by-step explanation:

Since BD is the angle bisector of ∠ABC, then

∠ABD = ∠CBD, that is

2x + y = 14 + y ( subtract y from both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Which equations are correct?
stepan [7]

Answer:

3y^5(2y^3+3)=−6y^8−9y^5

−2c^6(5c^3+6)=−10c^9−12c^6

are the correct equations.

Step-by-step explanation:

If you simply all these equations you will get following equations :

when bases are same and are in multiplication we add the exponents.

−4b^4(5b^2+6)=−20b^6−24b^4

−5x^3(3x^3+2)=−15x^6−10x^3

−3y^5(2y^3+3)=−6y^8−9y^5

−2c^6(5c^3+6)=−10c^9−12c^6

so equation 3 and 4 are correct.
