Step-by-step explanation:
<u>Arithmetic Sequences
</u>
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:

Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:

Operating:


Answer: D
Answer:
Riding 2 miles = $6.50
Riding m miles: C = 1.25m + 4
Step-by-step explanation:
(1.25)*(2) + 4 = $6.50
So since the shipping box is 3 / 3 1/4 you can fit 6 1/4 ÷ 2/4
Answer:
x = 11
Step-by-step explanation:
<u><em>Theorem:</em></u>
<em>The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.</em>
Angle ABC is an exterior angle of the triangle.
Angles D and C are its remote interior angles.
m<ABC = m<D + m<C
12x - 2 = 57 + 7x - 4
Combine like terms on the right side.
12x - 2 = 7x + 53
Subtract 7x from both sides.
5x - 2 = 53
Add 2 to both sides.
5x = 55
Divide both sides by 5.
x = 11
Answer: x = 11
