Step-by-step explanation:
<u>Arithmetic Sequences</u>
The arithmetic sequences are identified because 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 first terms of a sequence:
-12, -28, -44,...
Find the common difference by subtracting consecutive terms:
r = -28 - (-12) = -16
r = -44 - (-28) = -16
The first term is a1 = -12. Now we calculate the term n=61:



Answer:
Evidently, without the calculating 5 1/5 times 2/5 would be larger than 5 1/5 since you are already gonna multiply 2/5 and that would make it larger.
Hope this helps!
Branliest would be appreciated :DD
Step-by-step explanation:
Answer: 288
Workings : 16 x 12 =192 (for bottom rectangle bit) 12x 16 =192 then divide 192 by 2 =96 add them together and its 288
Answer:
.85 times the cost to make the shirt
Step-by-step explanation:
Let x represent cost to make the shirt.
Today, the shirt is in a 15 percent discount from its normal price.
Discount = 15/100 * x = 0.15x
Current cost = Original cost - discount
Current cost = x - 0.15x = 0.85x
The answer is;
.85 times the cost to make the shirt
Based on the calculations, the unknown number is equal to 
- Let the unknown number be x.
