Answer:
x +y =24
Step-by-step explanation:
(x - 8) 2 + (y + 2) 2 = 64
2x - 16 +2y+4 =64
2x + 2y =64-16
2x+2y = 48
divide both side with 2 we get
2x/2 +2y/2 =48/2
simplify
x + y =24
hence equation is x +y =24
Answer:
M=6

Answer:
5 km.
Step-by-step explanation:
We have to calculate the distance if we apply the speed formula that would be the distance in a given time:
v = d / t
therefore, if we solve for distance it would be:
d = v * t
Now the speed is 6 km / h but the time must be calculated, it leaves at 9:15 and returns at 10:05, that is, there is no exact time but 50 minutes, one hour equals 60 minutes, therefore:
50 min * 1 h / 60 min = 0.833 h, that is, the child took 0.833 hours to get to school, now if we replace:
d = 6 * 0.8333
d = 5
In other words, the distance between the school and the house is 5 km.
This is very simple, you can use tally marks to find the amount of birthdays. Then divide it by 100. Good luck !
