Answer:

x=6

y=5

Step-by-step explanation:

15x=90 (corresponding angles)

x=90/15

x=6

Now

5x+12y=90(vertical angles)

5(6)+12y=90

30+12y=90

12y=90-30

12y=60

y=5(dividing both sides by 12)

1 - (2n + 9) = 4(1-2)
Vikki [24]

Answer:

n=-2

Step-by-step explanation:

1−(2n+9)=4(1−2)

1+−1(2n+9)=4(1−2)

1+−1(2n)+(−1)(9)=4(1−2)

1+−2n+−9=4(1−2)

1+−2n+−9=−4

(−2n)+(1+−9)=−4

−2n+−8=−4

−2n−8=−4

−2n−8+8=−4+8

−2n=4

Divide both sides by -2

-2n/2=4/-2

n=-2

Divide this please urgent!
Sergeeva-Olga [200]

Answer:

3y² / x⁴z⁶

Step-by-step explanation:

12xy³z⁶ / 4x⁵yz¹² = 12/4 * x/x⁵ * y³/y * z⁶/z¹²

                           = 3 * 1/x⁴ * y² * 1/z⁶

                           = 3y² / x⁴z⁶
