Answer:

1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x

2. +3a+2a also equals +5a

3. - 5 is left alone and there is no other similar expression

Put them together the answer becomes

-3x+5a-5

It doesn't have to be the same order of format but the numbers must be as such

The students at a community center are participating in a bike riding fundraiser at a local park. A local company is donating $1

Oksi-84 [34.3K]

Answer:

This can not be properly answered, because we do not have the length of each trail.

The first step here will be find the length, in miles, for each of the four trails.

As students choose all four trails, the number of miles that each student will bike is equal to the addition of the lenght of the four trails.

Suppose this number is N.

So each student bike N miles, and the company donates $1.75 per mile. Then the amount of money that a single student is N times $1.75, or N*$1.75

When dealing with little odds you must know one part and the whole part. For number 1 a fraction , 7 is a part of a 11 which is the whole. For 2 a percent, 6% part and 100% whole, here you had to know that for 6% to exist there had to be a 100% . For 3 a ratio, the first number is part (2) and the second is whole (7). Look at pic for all work.
