Answer: 12a=48
Step-by-step explanation:
4a+6b=10
4a=10-6b
a=(10-6b)/4
a=(5-3b)/2
2a-4b=12
2((5-3b)/2)-4b=12
(5-3b)-4b=12
5-7b=12
-7b=7
b=-1
2a-4b=12
2a-4(-1)=12
2a+4=12
2a=8
a=4
a=4, b=-1
12a=48
The Pythagorean theorem tells you that distance is
.. √((-24)^2 +32^2)) = √(576 +1024) = √1600 = 40
Answer:
An imaginary line would need to be drawn at any angle to the center of the side opposite the angle to reflect across an axis of symmetry so that a regular pentagon can carry onto itself. Hope this answer helps.
Answer:
∠PQS= 3(x +5)
Step-by-step explanation:
∠PQR = 5x + 25
∠SQR+∠PQS= 5x+25
∠PQS = ∠PQR-∠SQR
∠PQS= (5x + 25 )-(2x + 10)
∠PQS = 5x+25 -2x-10
∠PQS= 3x +15
∠PQS= 3(x +5)
So you would just have to divide 20/7 to get the percentage of it.
The answer would be 2.85%.
