Answer:122° I think
Step-by-step explanation:
58+58=116
360-116=244
244/2=122°
3745(.0625/12)+1045(.1025/12)

Answer:
(4, 4 )
Step-by-step explanation:
Given the 2 equations
- 6x + 6y = 0 → (1)
9x - 8y = 4 → (2)
Multiplying (1) by 3 and (2) by 2 and adding will eliminate the x- term, that is
- 18x + 18y = 0 → (3)
18x - 16y = 8 → (4)
Add (3) and (4) term by term to eliminate x, then
2y = 8 ( divide both sides by 2 )
y = 4
substitute y = 4 into either of the 2 equations and solve for x
Substituting into (2)
9x - 8(4) = 4
9x - 32 = 4 ( add 32 to both sides )
9x = 36 ( divide both sides by 9 )
x = 4
Solution is (4, 4 )
8(7) = 56
7(6) = 42
6(5) = 30
5(4) = 20
4(3) = 12
3(2) = 6
∴ 3 = 6
