T - Shirts = $10
SweatShirts = 15$
24 *15 =360$
105 - 24 = 81
81 * 10 = 810$
810 + 360 = 1170$
T shirts = 81
Sweat= 24. /A\is the correct Answer
A = 1/2bh = 1/2(23)(7) = 80.5
answer
D. 80.5
Numbers with negative numbers become smaller such as decimals. Numbers with positive exponents become bigger in quantity
-50 + 17 = - 33
-33 + 17 = -16
- 16 +17 =1
This is arithmetic sequence, where 1st term is -50,
and common difference is 17.
Formula for the term of arithmetic sequence
a(n) = a(1) +d(n-1) = -50 +17(n-1) = -50 +17n - 17 = -67 +17n
So, we can write a formula
a(n) = -67 +17n
