Step-by-step explanation:

4: To <em>evaluate </em>an algebraic equation, replace each variable with the given number, and carry out the computation.

-This is basically explained the steps of evaluating an equation. You are receiving a number for x, so you then simplify and find if ?=? is true.-

<em>8 more than a number.</em>

<em>A number increased by 8.</em>

<em />

24. 8-y

<em>(Just the opposite.)</em>

<em>A number less than 8.</em>

<em>8 decreased by a number.</em>

<em />

<em>34. (I don't see the problem for this one.)</em>

Answer:

127 degrees

4.5, 9, 13.5, 18...
Sladkaya [172]

Answer:

a) Arithmetic

b) 22.5

c) 4.5

d) a_n = 4.5 + 4.5(n - 1)

e) a_15 = 67.5

Step-by-step explanation:

a) Subtract one term by the term right before it, and the difference will be the common difference.

9 - 4.5 = 4.5

13.5 - 9 = 4.5

18 - 13.5 = 4.5

Therefore, the common difference is 4.5.

b) Since the common difference is 4.5, add 4.5 to the 18 (which was the last value given). The result is 22.5.

c) We have already figured out that the common difference is 4.5.

d) The explicit formula would be a_n = a1 + d(n - 1). The first term is 4.5 and d is also 4.5, so the explicit formula is a_n = 4.5 + 4.5(n-1).

e) Plug 15 into our explicit formula for n. a_15 = 4.5 + 4.5(14). The result is 67.5.
