Answer:

y=2

Step-by-step explanation:

multiply each side by 27 to get rid of the denominator

3(3y-6)= -9(4-2y) is what is left

solve

9y-18=-36+18y

9y=18

y=2

You can also plug in 2 to the equation to check.

All the angles of a triangle add up to 180 degrees.

30+39+<4= 180

69+<4= 180

Subtract 69 on both sides.

<4= 111 degrees

<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.

111+<1= 180

<1= 69 degrees

I hope this helps!

What is a surface area of the cuboid with 4,5 and 9

Anettt [7]

Answer:

SA = 202

Step-by-step explanation:

Surface area = Sum of all 6 areas of each side of the cuboid

SA = 2 (4·5 + 5·9 +9·4), because there are 2 of each kind of sides

SA = 2 (20+ 45 + 36)

SA = 2·101
