Answer: 92
Step-by-step explanation: diagonally across would also be 88 so 88+88 is 176 and the total needs to be 360 so 360-176=184 so 184 divided by 2 is 92 which is your answer
Let his total money be x.
He spent (3/7)*x of his money.
He gave 1/4(x-3/7x) to his sister.
which is : (1/4)*(4/7)*x = (1/7)*x
Now,
How much money he have in the beginning =
(3/7)*x+(1/7)*x+120=x
(4/7)*x+120=x
120=x-(4/7)*x
120=(3/7)*x
x=120*7/3 [cross multiplication]
x=280.
So, Alex had $280 in the beginning.
21160000

5p= -12
5p/5= -12/5
p= -12/5
