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.
The equation of a cirecle with radius r and center at (h,k) is
(x-h)^2+(y-k)^2=r^2
r=10
center=(-2,-4)
(x+2)^2+(y+4)^2=10^2
(x+2)^2+(y+4)^2=100
(x,y)

4.5 the finest in a wide range is to make the best choice of
150 minutes : 3 1/2 hours
3 1/2 hours = 3.5 hours = 3.5 * 60 = 210 minutes
150 minutes : 3 1/2 hours = <span>150 minutes : 210 minutes
</span>
= 150:210
= 15 : 21
= 5 : 7
The range is 10 to 40 and then the rest .
