2.645 squared equals 7. Save --------- Unclear what you're asking: If x=7, then x^2 (that is, "x squared") equals 49. or If x^2=7, then x equals the square root of 7, or about 2.64575
21.65640 x 21.65640
67% of x = 67 0.67 x = 67 x=67/0.67 x=100
x = 100
67 x 1 = 67
7 out of 67 equals 10.44776%

1 x 67
no, 7 times 7 equals 49 67 is a prime number and therefore does not have any other factors other than 1 and 67
Let me see:1) x + y + z = 7 y = 7 - x- z2) 2x + 3y- z = -23) -x + 3z = 36 x = 3z - 36Subst. 3) into 2):2(3z-36)+3y -z = -2Subst 1) into 3):2(3z-36) +3(7-x-z) - z = -2Subst 3) into 2) again:6z-64 + 3(7-(3z-36) - z) -z = -2z= 67/7Subst answer into 3) -x + 3(67/7) = 36x = -51/7Subst answers into 1):-51/7 + y + 67/7 = 7y = 33/7therefore x = -51/7, y = 33/7, z = 67/7
