64=-4+4x
64+4=4x
68=4x
68/4=x
17=x
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
m + g + 30 = t
If m = 40 and t = 95,
g = t - m - 30 = 95 - 40 - 30 = 25.
A whole number? ok. 24x10^4. usually though you would use standard form so it would be 2.4x10^5
Answer is .47
Fourty seven hundredths in standard form is .47,
