one is the biggest common multiple. multiplying into 2 twice and 3 three times.
Answer:
15 cm
Step-by-step explanation:
Circumference of circle= 2πr, where r us the radius of the circle.
Given that the circumference of circle is 60πcm,
60π= 2πr
Divide by 2 on both sides,
15π= πr
Divide by π on both sides,
15= r
Thus, radius of circle= 15cm.
One clock of any type costs $3.20. a clocks cost 3.2a. w clocks cost 3.2w.
Add 3.2a to 3.2w to find the total cost.
T = 3.2a + 3.2w
T = 3.2(a + w)
Both expressions above are correct answers.
Answer: See below
Explanation:
1a.
-4 • 1 = 8(y-5)
-4 = 8y - 40
-8y = -40 + 4
-8y = -36
Y = -36/-8
Y = 9/2
1b.
3c - 6 = -6 + 9(c+9)
3c - 6 = -6 + 9c + 81
3c - 9c = 75 + 6
-6c = 81
C = 81/-6
C = 27/-2
2a.
6(p-2) = -2 + 3
6p - 12 = 1
6p = 13
P = 13/6
2b.
3x - 4 = -3 + 4(x - 3)
3x - 4 = -3 + 4x - 12
3x - 4x = -15 + 4
-x = -11
X = 11
