1)before simplifying, how many terms are there in the expression 2x - 5y + 3 + x? 3 4 5 6 2) which of the terms cannot be combined with the others? 3a a 5b -2a 3) which of the terms cannot be combined with the others? -3x 4x 2 x 11x 4) all of the following are equivalent except 7x 2 4x + 3x (4 + 3)x 7x 5) which of the following is not equivalent to x - y + z? x + z - y z + x - y y - x + z z - y + x

1. Option B, i.e., 4

2. Option C, i.e., 5b

3. Option B, i.e.,

4. Option A, i.e,

5. Option C, i.e., y - x + z

Step-by-step explanation:

1.

The given expression is

We need to find the number of terms in the given expression.

Here, the terms are 2x, -5y, 3 and x.

Therefore, the number of terms is 4. Option B is correct.

2.

If two or more terms have same variable of same degree, then they are called like terms.

3a, a and -2a are like terms but 5b is not a like term.

Therefore, 5b cannot be combined with the others. The correct option is C.

3.

Similarly,

-3x, x and 11x are like terms but is not a like term because the degree of x is 2.

Therefore, cannot be combined with the others. The correct option is B.

4.

The given expressions are

It can be rewritten as

It means expression 4x+3x, (4+3)x and 7x are equivalent.

Therefore, All of the following are equivalent except . Option A is correct.

5.

The given expression is

x - y + z

It can be rewritten as

x + z - y

z + x - y

z - y + x

All of the following are equivalent except y - x + z. Therefore, option C is correct.

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
