1 tenths is equal to 1/10. let x be the unknown number of tenths, then: (1/10)*x = 5 x/10 = 5 x = 50 Therefore, 50 tenths equals 5.
0.06 x 5 = 3/10
To convert tenths to thousandths, you multiply by 100. Therefore, 2 tenths is equal to 2 x 100, which equals 200 thousandths.
5-x equals 7 = -2
x=2*5 x=10
2/5 x 2/2 = 4/10 1/2 x 5/5 = 5/10 4/10 + 5/10 = 9/10 9 tenths
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
2= x + 5 2 - 5 = -3 x= -3
2+5 = 7
x/y = 5/(y^2) and y/x = 5/(x^2). So x/y + y/x = 5/(y^2) + 5/(x^2), which equals 5x^2/(x^2 y^2) + 5y^2/(x^2 y^2) equals 5(x^2 + y^2)/25 equals (x^2 + y^2)/5. x^2 = 25/y^2, so you get (25/y^2 + y^4/y^2)/5 equals ((25 + y^4)/y^2)/25, which shows that your math teacher is on crack. Seriously, I'm not sure that's true.
If x=2, then 7x = 14 and if y=5 then 4y=20.
