2x + 5y = 26....multiply by 3
3x + 4y = 26...multiply by -2
------------------
6x + 15y = 78 (result of multiplying by 3)
-6x - 8y = - 52 (result of multiplying by -2)
-----------------add
7y = 26
y = 26/7 (or 3 5/7)
2x + 5y = 26
2x + 5(26/7) = 26
2x + 130/7 = 26
2x = 26 - 130/7
2x = 182/7 - 130/7
2x = 52/7
x = 52/7 * 1/2
x = 52/14 which reduces to 26/7 (or 1 5/7)
solution is : (26/7, 26/7)
Answer:
16
Step-by-step explanation:
Simplify the following:
4 + 3×2^3/2
3×2^3/2 = (3×2^3)/2:
4 + (3×2^3)/2
Combine powers. (3×2^3)/2 = 3×2^(3 - 1):
4 + 3×2^(3 - 1)
3 - 1 = 2:
4 + 3×2^2
2^2 = 4:
4 + 3×4
3×4 = 12:
4 + 12
4 + 12 = 16:
Answer: 16
Answer:
160°
Step-by-step explanation:
1/2 (Major arc AB - Minor arc AB) = 20°
Major arc AB = 200°
Minor arc AB = 160°
central angle = minor arc AB = 160°
