Answer:
Michael is 21 years old while Jean is 7 years old.
Step-by-step explanation:
Given that Micheal is three times as old as Jean, but in seven years he will be twice old as she will be, to determine how old are they both at this time, the following calculation must be performed:
M = 3J
M + 7 = 2J + 7
7 = 1/3
7 x 3 = 21
21 + 7 = 28
7 + 7 = 14
21 / 7 = 3
28 / 14 = 2
Therefore, Michael is 21 years old while Jean is 7 years old.
Answer:
D is 90 E is 81 F is 99
Step-by-step explanation:
D is 90 because a straight angle equals 180 degrees. E is 81 because it is directly across from 81. F is 99 because 180-81 is 99
Circles follow ghe equations
(x-h)^2 + (y-k)^2 =r^2
with center (h,k) and radius r
for this circle it would be
(x-7)^2 + (y-4)^2 = 100
