If 3x – 5y = 5 and x/x + y = 5/7, then what is the value of x – y ?
If √18x14xX=84 then x equals:
(3² * 4² * 5) ÷ 36 = (?)²-80
If a + b + c = 13, a2 + b2 + c2 = 69, then find ab + bc + ca.
If in a code, 52 – 36 = 97 and 46 – 78 = 1510, then how 53 – 62 can be encoded?
The value of 1001 + 11 of 13 is:
415% of 620 =?
(2√27-√75+√12) is equal to:
76% of (?) – (11)² = 525
9050 ÷ 40=?
