How can you use 2, 3, 5 and 8 to get 104?
Tamiku [17]
Salma showed me how to do it.

Here are two ways:

8 times (5·3 - 2)  =  8 times (15 - 2)  =  8 times 13  =  104 .

8 times (5·2 + 3)  =  8 times (10 + 3)  =  8 times 13  =  104.

Thank you, Salma.

If AB=x+4, BC=2x-10, and AC=2x+1, then find the value for AC.
brilliants [131]
If AB and BC are equal then AC should be 29

How did I get this?
x+4=2x-10
14=x

Plug it in
AC= 2(14)+1
AC=28+1
AC=29

KEEP IN MIND THIS WILL MOSTLY LIKELY ONLY WORK IF IT SAYS AB AND BC ARE EQUAL
