83 less than a number n

Answers

The answer could be anything. If there is no number for n, then you probably need to make one up. For example, 83 less than 123 is 40. So, if it did give you a number, comment it and I will help you further. Hope this helps. :)

d)

Answers

Answer: A

Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added or subtracted.

Notice that in the the first sequence shown, we add 4 to reach the next term in the sequence which means this is arithmetic.

The others are not arithmetic because the difference

between the terms does not remain constant.

there are 33 students in the band there are more 5th grade students than 3rd grade students there is an equal number of 3rd grade and fourth grade students how many third grade students are in the band

Answers

Use A for third graders, B for fourth graders, and C for fifth graders.

33 = A + B + C

Since there are 3 variables, you need to come up with two other equations to substitute in.

C = 6 + A Since there are six more fifth graders than third graders.

A = B Since there is an equal amount of third and fourth graders.

Since A is in both equations, then lets put each variable in terms of A.

B = A

C = 6 + A

So:

A + A + A + 6 = 33

A + A + A = 27 Since you subtract 6 from both sides.

3A = 27 Since you combine all three A's.

A = 9 Since you divide both sides by three.

Therefore, since A is a number of third graders, there are 9 third graders.

(Sorry if there's any typos.

Answer:

there are 9 third graders

Answers

Even if I and M looks parallel... they are not.

To be parallel, the internal alternate angles must be equal. (hope this is the name...)

So, 124≠118 => I and M aren't parallel

Line I and Line M both are NOT parallel to each other because angles 124 and 118 are different.
