Answer:
x = 1
Y = 1
Step-by-step explanation:
A. 3(2x-3y= - 1)
6x-9y=- 3
B. -2(3x-4y= - 1)
- 6x+8y=2
Add both equations:
(6x-9y= - 3) + (- 6x+8y=2)
-y= - 1
3x - 4(1) = - 1
3x-4= - 1
3x = 4 - 1
= 3/3 = 1
Answer:
3. 14 cm
Step-by-step explanation:
Solve for radius first using the equation for circumference:
C = 2πr
44 = 2πr
44/2π = r
r = about 7 cm
d = 2r
d = 2*7
= 14 cm
They can make the numbers 13, 46, 45, 64, 65, 64, 41, 43, 14, 15, 16, 34, 35, 36, 32, 62, 42, 12, 51, 52, 53, 54, 55, 56.
