R + w = 50
r = 6w + 1
now we sub ..
6w + 1 + w = 50
7w + 1 = 50
7w = 50 - 1
7w = 49
w = 49/7
w = 7 <== white beads
r = 6w + 1
r = 6(7) + 1
r = 42 + 1
r = 43 <=== red beads
Answer:
2
Step-by-step explanation:
We know that the opposite sides of a parallelogram are equal so:
25x+1=7x+37
18x=36
x=2
Answer:
mass - 1395.28 g
Step-by-step explanation:
density = mass / volume
65.2 g/cm^3 = mass / 21.4 cm^3
65.2 g * 21.4 = mass (cm^3 cancels out)
1395.28 g = mass
