Answer:
x = 68°
Step-by-step explanation:
∠ DCB = ∠ EDC = 27° ( alternate angles )
Thus ∠ ECB = 23° + 27° = 50°
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (62 + 50)° = 180° - 112° = 68°
1 + {[(1 * 0.5) x 12] x 3}
1 + {[0.5 x 12] x 3}
1 + {6 x 3}
1 + 18
19
I'm not sure if that's a 1.000 or 1,000 so:
1,000 + {[(1,000 * .5) x 12] x 3}
1,000 + {[500 x 12] x 3}
1,000 + {6,000 x 3}
1,000 + 18,000
19,000
43 billion in scientific notation is:
4.3 × 10^10
Answer:
yes
Step-by-step explanation:
Substitute x = 2 and y = 5 into the left side of the equations and if equal to the right side then they are a solution.
x + 2y = 2 + 2(5) = 2 + 10 = 12 ← True
3x + 6y = 3(2) + 6(5) = 6 + 30 = 36 ← True
Thus x = 2, y = 5 is a solution to both equations
Yes it is equivelant because if u use ditributive property is will give u the same answer
