Multiply the equations to get the coefficients Greatest Common Factor:
3(2x+4y=11)
2(3x+6y=17)
6x+12y=33
6x+12y=34
Then you subtract them:
0x+0y=-1 0=-1
Or in other words no solutions
Answer:
75 miles
Step-by-step explanation:
cross multiply
1/30 = 2.5/x
x= 2.5 * 30
x=75
r = 9 yd
C = 2 π r ≈ 2 (3.14) (9 yd) = 56.52 yd
A = π r² ≈ (3.14) (9 yd)² = 254.34 sq yd
Answer: Circumference: 56.52 yd Area: 254.34 sq yd
