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.
2=4(-3) + b
2= -12 + b
14= b
Y=4x + 14
Marie because if you put a 0 behind .4 that equals .40 and then you compare .25 and .40 therefore .25 is closer
