Answer:
The vale of x=4
Step-by-step explanation:
We know that the sum of angles of a triangle = 180°
Given
Thus, the equation becomes
(3x+13) + (8x+14) + 109° = 180°
11x + 27 + 109° = 180°
11x = 180°- 109° - 27
11x = 44
x = 4
Thus, the vale of x=4
The answer to 1 is common multiple. And the answer to 2 is common denominator
Answer:
1648.5
Step-by-step explanation:
20cm radius - 10
50cm radius- 25
area = 3.14×10²
3.14×100
=314
area= 3.14× 25²
3.14×625
= 1962.5
1962.5
- 314
_________
1648.5
They are 7 points away from each other.
Answer:
It has a single solution x=-3 y=26
Step-by-step explanation:
The ratios of coefficients of x and y are different, so the pair of equations has one solution. It is easy to tell the first offered solution (15, 17) does not satisfy the first equation, so that choice is eliminated.
Fortunately, the second offered solution, (x, y) = (-3, 26), satisfies both equations.
The equations have a single solution: (x, y) = (-3, 26).
