Answer:
x = 8 and y = 10
Step-by-step explanation:
Since the figures are congruent:
Angle PQR = EFG
6y + x = 68
Segment QR = FG
2x - 4 = 12
Solving that:
2x - 4 = 12
2x = 16
x = 8
Replacing x in 6y + x =68
6y + 8 = 68
6y = 60
y = 10
The formula for the circumference is 2πr.
The diameter d is given, which is 2 times the radius r (d = 2r)
So you have to calculate π d = 3.142×1.8 ≈ 5.7
Answer:
Infinite
Step-by-step explanation:
3x+15=2x+10+x+5
grouping
3x+15=3x+15
If you have a equation where both sides are the exactly the same, the solutions are infinite. This is written as: x€ℝ
Answer:
3x
Step-by-step explanation:
coefficient is the number before the variable
