4(3x – 2) + 6x(2 – 1)12x - 8 + 12x -6x18x - 8
answer is 18x – 8
(Y) me 30 minutes longer (X) brother
brothers total minutes read are equal to my minutes read plus 30 more minutes
X= Y+30
1:3 or 1 to 3. First write 12:36 and then simplify which gives you 1:3 or 1 to 3
0<x<1 and 0<y<1
x>0 so x is positive and y>0 so y is also positive.
When you multiply two positive numbers you always get a positive number, so the product of x and y must be positive, or greater than 0.
xy>0 - it must be true
xy<0 - it can't be true
Also when you divide a positive number by a positive number you always get a positive number, so the quotient of x and y must be positive.
x/y<0 - it can't be true
D and E can be true, but don't have to. It depends on the values of x and y. If x>y, then x-y>0 is true and x-y<0 isn't true; if x<y, then x-y>0 isn't true and x-y<0 is true.
Therefore, only A <u>must</u> be true.
