square root of 4, 6.5, 6 and 2 thirds, 7, square root of 50, and 630%
(-3)^3, - square root if 65, -8.2, -8 and 2 fifths, - square root of 78, and -(3)^2
Let M be the age of Maggie and B the age of her younger Brother:
Rewrite the problem from English language to Math's:
B = 2.M - 10 (1)
and M + B = 29 (Given) OR B = 29 -M (2)
Plug 2) into 1):
29 -M = 2.M -10
29 + 10 = 3 M →→3M = 39 and M = 39/3 = 13
Replace M by 13 and you will find B =6
Then Maggie = 13 year old and her brother B = 6 year old
