-1/2x < -12
Divide both sides by -1/2
Also because you are dividing by a negative number you need to reverse the inequality sign.
X > 24
The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
If m and n are parallel, then that's like saying 3x-10 is equal to 5x-30 (or 3x-10 = 5x-30).
If that's the case, then You'll need to format the problem so you can solve for x. In order to solve this equation, we need to group all the variable terms on one side, and all of the constant terms on the other side of the equation.
So the -10, will be moved to the right side and the 5x will be moved to the left side. Also as each term that moves, it causes their signs to change.
So we now have the problem of 3x-5x=10-30. Now we can start to simplify the problem by combining like terms.
So 3x-5x = -2x and 10-30=-20 or more simply -2x=-20
Now we need to isolate the variable x so it's on a side by itself.
The easiest way to do this is simply divide both sides by 2, which gives us 2x/2=20/2 or more simply, x=20/2.
So we're down to the simple problem of x=20/2 which equals 10. So x=10.
It would be A because 1/2 of 2000 is 1000 not 900
