Answer:
B. x≥-3
Step-by-step explanation:
To solve this problem, first you have to isolate it one one side of the equation.
First, multiply -1 from both sides.
(-9x)(-1)≥27(-1)
Solve.
27*-1=-27
9x≥-27
Next, divide by 9 from both sides.
9x/9≥-27/9
Then, solve.
-27/9=-3
Therefore, the correct answer is x≥-3.
Answer:
original width= 9.6 feet
original length = 38.4 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the formula
P =2w +2 L
Where:
P=perimeter
W= width
L = length
Since the field is 4 times as long as it is wide
L= 4W
So, if the length is decreased by 10 feet and the width is increased by 2 feet, the perimeter will be 80 feet.
Mathematically speaking
80= 2 (W+2) + 2(L-10)
Simplifying:
80 = 2w+4 +2L-20
Replacing the value of L by 4W
80 = 2W +4 +2(4W)-20
Solving for W:
80=2W +4 +8W-20
80-4+20= 2W+8W
96= 10W
96/10 =W
W= 9.6 feet
Replacing the value of W in the Length equation:
L =4W
L = 4 (9.6)
L = 38.4 feet
