The answer is
D.1
because even though there is not a number in front of X, we are to assume it is 1.
Answer: x ≥ 6
Step-by-step explanation:
So 6 - 20 would equal -14 which is greater than -15 making it our inequality equal to or greater then 6
Yes because it has 0 in it
In short, let x be the height of the Light House
2.5/36 = 1.5/X
===> X= (36 x 1.5)/2.5 = 21.6 meters
Let the unknown number be y.
We can list the equation out by the clues given.
5y + 12 = 52
Then solve this as simple algebra!
Shift +12 to the other side and be - 12
5y = 52-12
5y = 40
Shift x5 to the other side and be ÷5
y = 40 / 5
y = 8
Therfore the unknown number is 8.
