Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
Answer:
12.000
Step-by-step explanation:
40000x6= 240000/100= 2400x5
2(5-6)<8f-130
(2x5)-(2x6)<8f-130
10-12<8f-130
-2<8f-130
-2+130<8f-130+130
128<8f
128/8<8f/8
16<f
f>16
