Step-by-step explanation:
R' = (-2,0)
E' = (-2,2)
F' = (4,4)
42 (1- 25/100) = 63/2 = 31.5 dollars
answer is $31.50
hope it helps
To answer the question above, we let s be the cost of a shirt and h be the cost of each hat such that the equations that would best represent the given are:
10s + 20h = 490
20s + 30h = 860
The system of equations is the answer to the first question and the values of s and h are $25 and $12, respectively.
The answer is A. 88.8 cm2
Work:
74 x 2 = 148
14.8 = 29.6
Add them = 177.6
then
