Lyrx [107]

Answer: 29, 30, 35, 36

Step-by-step explanation:

As per your info about first page.

The paper containing 64 has following other pages

On the back of 29, it is 30. The pages are such that for each page p, 65-p will be also on the same page.

Then,

65-29= 36

65-30 = 35

So the four pages in this sheet are 29, 30, 35, 36.

Please help with 8 and 10 ..
Natalka [10]

Answer:

8) Parallelogram.

10) Point W.

Step-by-step explanation:

8) Give another name of plane V.

As shown the plane represents A flat shape with 4 straight sides where opposite sides are parallel and also opposite sides are equal in length.

So, plane V represents parallelogram

10) Name a point that is not coplanar with R, S and T.

Coplanar points are the points which all lie in the same plane.

So, as shown:

R, S and T are coplanar points, they all lie in the plane V

So, the point which doesn't lie in the plane V is the point W

So, <u>the point W</u> is not coplanar with R, S and T.

13. 3(x-6)-8=-2 (you have to plug in x-6 as x in the equation

3x-18-8=-2 (distribute 3)

3x-26=-2 (combine like terms)

3x=24 (subtract 26 to both sides)

x=8 (divide 3 to both sides)

14. -2(3(5y+5)=-4

-2(15y+5)=-4

-30y-10=-4

30y=6

y=1/5

15. (3x-5) +2x = 90

16. Let m be the number of minutes

0.75m+32 = 47

Using this equation you can find the number of minutes.

0.75m = 15 ( subtract 32 to both sides)

m= 20 (divide 0.75 to both sides)

Vera called 20 minutes beyond her allowed minutes.


Here I hope that this helped you out hon :)
