(2) + (2)
=> 8x - 6y = -46 ———(3)
(1) + (3)
=> 5x + 6y + (8x - 6y) = 20 - 46
=> 13x + (6-6)y = -26
=> 13x + 0y = -26
=> 13x = -26
=> x = -26/13
=> x = -2
=> 5(-2) + 6y = 20
=> 6y = 20 + 10
=> 6y = 30
=> y = 5
x = -2, y = 5 => C
Answer: 49.09 cm2
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Circumference of a circle = π x diameter = 3.14159x 3 1/8 = 9.81746 in
The circumference of the can is equal to the length of the rectangular label:
Surface area (S)= circumference(length) x height
Replacing with the values given:
S = 9.81746 x 5 = 49.09 cm2
Feel free to ask for more if needed or if you did not understand something.
The best answer is C : The sum of the measures of two angles os 180 degrees .
Interest = p times R times T
