Answer:
-2.23, -2 2/5, -0.95
Step-by-step explanation:
-15/16 = -0.9375 (greater than -0.94)
0.24 (greater than -0.94)
-2.23 (less than -0.94)
97% = 0.97 (greater than -0.94)
-2 2/5 = -2.4 (less than -0.94)
-0.95 (less than -0.94)
Answer:
34 years
Step-by-step explanation:
f = s + 28 Eq. 1
f+8 = 3(s+8) Eq. 2
f = father age
s = son age
replacing Eq. 1 on Eq. 2
(s+28) + 8 = 3(s+8)
s + 36 = 3*s + 3*8
s + 36 = 3s + 24
36 - 24 = 3s - s
12 = 2s
12/2 = s
s = 6
from the Eq. 1
f = 6 + 28
f = 34
Check
from the Eq. 2
34+8 = 3(6+8)
42 = 3*14
