a student bought 34 pencils for school. if he sharpened 16 of the pencils before school, what is his ratio of unsharpened pencils to sharpened pencils?

Answers

34 - 16 = 18

18 : 16 

I think that's the answer? 
TO find unsharpened pencils, subtract 34 by 16 and you'll get 18. The answer to the question is 18/16, if you want to simplified it, it will be 9/8 or 9:8.

8(t+2)-3(t-4=6(t-7)+8

Answers

8(t+2)- 3(t-4)  = 6(t-7)+8.   Looks like a lot of distributing.
8t+16 - 3t+12 = 6t-42 + 8. Now we can combine like terms.
         5t + 28 = 6t - 34.     Just solve normally.
                28 = t - 34.        Add 34 to both sides.
                   t = 62.

What is the GCF for 26 48 and 62 plese help

Answers

It's 2, the only factors 26 has is 1,2,13, and 26. So it has to be 2 since none of the other factors relate to the other numbers.
All three numbers are even there for can all be divided by 2.
If you divide 26 by 2 you get 13
48 by 2 you get 24
and 62 by 2 you get 31
the GCF is 2

A rectangular garden has an area of 800 m. If it is 25 meters wide, find the cost of fencing it at $12 per meter.

Answers

Here, we need to find out what is the length of the rectangle. To do this, we'll divide 800 by 25:   800/25 = 32

So we now know that the length is 32 m and the width is 25 m. So we can now find the perimeter:

(32 + 32) + (25 + 25) =
64 + 50 = 114

The perimeter is 114 m. To find how much is will cost to fence 114 meters, we'll multiply the number of meters by the cost per meter: 114 * $12 = $1368

It will cost $1368.
