b
Step-by-step explanation:
Answer:
48
Step-by-step explanation:
Area of a square = length of side squared
square root of 144 is 12
four equal sides in a square
12 * 4 = 48
675.00/1650.00 = 0.4090...
(0.4090)(100) = 40.9
The answer is C. 40.9%.
2x + 3y = 12 (1st)
5x − y = 13 (2nd) ---> y = 5x - 13
Substitute y = 5x - 13 into (1st) equation
2x + 3(5x - 13) = 12
2x + 15x - 39 = 12
17x - 39 = 12
17x = 51
x = 3
substitute x = 7 into y = 5x - 13
y = 5x - 13
y = 5(3) - 13
y = 15 - 13
y = 2
Answer
solution x = 3 and y = 2
